Astros' Kai-Wei Teng: Sent down after Saturday's start
Rotowire
Teng was optioned to Triple-A Sugar Land on Saturday, Chandler Rome of The Athletic reports.
Teng made the start Saturday against Detroit and gave up five runs (four earned) on eight hits and a walk over 3.2 innings. That continued a rough June for the right-hander, who has given up at least four earned runs in four of his five starts this month. Teng's demotion to the minors makes room on the 26-man roster for reliever Miguel Ullola, who was recalled from Sugar Land on Saturday. However, Teng's spot in the rotation could soon be taken by Cristian Javier (shoulder), who tossed 75 pitches in his most recent rehab start Sunday and appears to be closing in on returning from the IL.

Astros' Kai-Wei Teng: Escapes with no-decision Saturday
Rotowire
Teng didn't factor into the decision Saturday in an 8-6 win over the Tigers, coughing up five runs (four earned) on eight hits and a walk over 3.2 innings. He struck out one.
A grand slam by Kerry Carpenter in the third inning accounted for most of the damage off Teng, but a late rally by Houston took the right-hander off the hook for his seventh loss of 2026. Teng has given up at least five runs in four of five June starts, and while some unearned runs have softened the blow to his ratios, he still carries a 7.77 ERA, 1.86 WHIP and 20:9 K:BB through 22 innings on the month. He's currently scheduled to make his next start at home next week against the Twins, but with Cristian Javier (shoulder) having built up to 75 pitches in his most recent rehab outing, Teng's time in the rotation may be about to end.

Astros' Kai-Wei Teng: Slated to start Saturday
Rotowire
The Astros announced that Teng would start Saturday's game against the Tigers, Matt Kawahara of the Houston Chronicle reports.
Cristian Javier (shoulder) appeared to be a candidate to come off the 60-day injured list to start Saturday in Detroit, but the Astros will instead give Teng another turn through the rotation while Javier continues to work his way back. Teng had a nice bounce-back outing against the Guardians in his last start Sunday, allowing just one run on four hits and one walk with four strikeouts over six innings to pick up his fourth win.

Astros' Kai-Wei Teng: Six strong innings in fourth win
Rotowire
Teng (4-6) earned the win Sunday against Cleveland, allowing one run on four hits and one walk in six innings. He struck out four.
Teng delivered one of his finest starts of the year, tying a season high in innings in his second quality start. The 27-year-old right-hander is still settling into his transition in Houston's rotation, logging a 5.13 ERA, 1.51 WHIP and 42:20 K:BB across 40.1 innings as a starter this year. Given that he sports a 1.80 ERA, 0.85 WHIP and 20:7 K:BB over 20 frames as a reliever, Teng could revert back to the bullpen once Cristian Javier (elbow) is ready to return to action.

Astros' Kai-Wei Teng: Posts another scoreless start
Rotowire
Teng (3-3) notched the victory over the Cubs on Saturday, allowing two hits and walking three batters while striking out six over six scoreless innings.
Teng tossed a season-high 89 pitches (56 strikes) while completing six frames for the first time as a major leaguer. The right-hander also recorded his second straight win and has now thrown 11 scoreless innings while allowing just four hits and registering a 13:7 K:BB over his past two starts. Teng has moved into Houston's six-man rotation this month and has gradually increased his pitch count with the aim of remaining a starter long term. He's tentatively stated to next take the mound at home versus Milwaukee.

Astros' Kai-Wei Teng: Tagged with loss Tuesday
Rotowire
Teng (1-2) took the loss Tuesday as the Astros fell 5-3 to the Orioles, giving up two runs on five hits over three innings. He struck out two.
Kicking off a bullpen day for Houston, Teng lasted a season-high 42 pitches (30 strikes) before being lifted, with Ryan Weiss piggybacking him for another 3.2 frames. Teng has provided useful innings so far on a patchwork staff, posting a 2.75 ERA, 1.02 WHIP and 18:6 K:BB over 19.2 innings in 12 appearances (one start), but his current role doesn't carry a lot of fantasy utility -- the 27-year-old right-hander has one win and one hold in that span. If the Teng/Weiss tandem takes another turn in the rotation, it lines up to come on the road this weekend in Boston. If the Astros look to Triple-A Sugar Land instead for a starter, Miguel Ullola would be on turn and threw 5.1 innings Tuesday, albeit with a 5:4 K:BB.

Astros' Kai-Wei Teng: Will be used as opener
Rotowire
Teng is slated to serve as an opening pitcher in Tuesday's game in Baltimore, Chandler Rome of The Athletic reports.
Teng has recorded more than three outs in seven of 11 relief outings this season, so he could cover more than one inning Tuesday. However, he's not stretched out enough to make a typical start, so Houston will be treating Tuesday's contest as a bullpen day. Ryan Weiss is a candidate to cover multiple innings in relief once Teng exits the game.

Astros' Kai-Wei Teng: Tapped for start Tuesday
Rotowire
Teng has been named the Astros' starting pitcher for Tuesday's game in Baltimore, Matt Kawahara of the Houston Chronicle reports.
Tuesday had been Ryan Weiss' turn in the rotation, but Weiss appears headed back to the bullpen. Teng has pitched well as a multi-inning reliever this season, collecting a 2.16 ERA, 0.90 WHIP and 16:6 K:BB across 16.2 frames. The right-hander made seven starts last season for the Giants and was deployed mostly as a starting pitcher in the minors, so he shouldn't require a lengthy period of time to get fully stretched out. However, with Tatsuya Imai (arm) poised to return from the injured list, Teng's stint in the rotation could be brief.

Astros' Kai-Wei Teng: Tagged with loss in relief
Rotowire
Teng (1-1) was tagged with the loss Saturday against the Yankees after allowing one run on two hits in one-third of an inning.
This was just the fourth run Teng has allowed this season, though it's worth noting that three of those have come via solo home runs. Despite being tagged with the loss and lasting just one-third of an inning Saturday, Teng has enjoyed a strong start to the campaign and sports a 2.16 ERA through 16.2 frames.

Astros' Kai-Wei Teng: Scoreless outing vs. A's
Rotowire
Teng threw 2.1 scoreless innings in Saturday's 11-0 win over the A's, allowing two hits while striking out three.
Teng has gotten off to a nice start this season, allowing just one run on four hits and one walk over 5.2 innings in his first three appearances. Teng, who posted a 6.37 ERA across 29.2 innings in a swingman role with the Giants last season, earned a spot in Houston's Opening Day bullpen as Bennett Sousa (oblique), Enyel De Los Santos (knee), Nate Pearson (elbow) and Josh Hader (biceps) all opened the year on the IL.

Giants' Kai-Wei Teng: Fans six in three-inning start
Rotowire
Teng allowed two runs on a hit and two walks while striking out six over three innings in a no-decision versus the Dodgers on Saturday.
Teng threw just 39 of 74 pitches for strikes but was able to limit the damage to a two-run home run by Max Muncy in the first inning. The Giants look to be limiting Teng's workload -- he's reached the five-inning mark in just two of his eight major-league appearances this season. He's at a 6.37 ERA, 1.55 WHIP and 39:17 K:BB through 29.2 innings with the big club. Teng could get one more appearance this season, which is tentatively projected to be at home versus the Rockies in the final series of the year.

Giants' Kai-Wei Teng: Records victory Monday
Rotowire
Teng (2-3) earned the win over Colorado on Monday, allowing two runs on nine hits and no walks while striking out eight batters over 5.1 innings.
Teng struggled with an 8.78 ERA over four starts in August prior to a brief minor-league demotion, but he looked like a different pitcher Monday. Not only did the right-hander limit the Rockies to two runs, he also fanned eight batters, doubling his previous season-best mark. Teng did allow traffic in all but one of his frames, but the Rockies didn't score on him until after he gave way for a reliever with one out in the sixth. Teng figures to get another turn in the rotation given this strong outing, and he lines up to face the Cardinals in St. Louis this weekend.

Giants' Kai-Wei Teng: Going back to minors
Rotowire
The Giants optioned Teng to Triple-A Sacramento on Thursday.
Teng has had an excellent season in the minors, but thus far that hasn't translated at the big-league level, as he's posted an 8.78 ERA and 12:9 K:BB over 13.1 frames covering three starts and one relief outing. He'll try to get back on track and earn another opportunity later this season.

Giants' Kai-Wei Teng: Rough day vs. Padres
Rotowire
Teng (1-2) took the loss Wednesday against San Diego, allowing seven runs (six earned) on four hits and four walks over 1.2 innings.
After tossing a scoreless first inning, Teng unraveled in the second, allowing six straight batters to reach after recording the first out. It's a disappointing showing from Teng, who held the Nationals scoreless over five innings in his previous appearance. With Landen Roupp (elbow) expected to rejoin the Giants' rotation Friday, Teng will likely head back to Triple-A or assume a bullpen role.

Giants' Kai-Wei Teng: Starting Wednesday
Rotowire
Teng will draw the start in Wednesday's contest against the Padres, Shayna Rubin of the San Francisco Chronicle reports.
Teng will return to the mound to make his second start of the season with San Francisco. The right-hander worked behind opener Matt Gage in Friday's win over the Nationals, tossing five scoreless innings while striking out four batters. Over two outings, Teng owns a 5.40 ERA and 1.32 WHIP with eight punchouts over 8.1 innings, and he'll look to step up to the challenge against an impressive Padres group.

Giants' Kai-Wei Teng: Works well behind opener
Rotowire
Teng (1-1) allowed three hits and a walk while striking out four over five shutout innings to earn the win over the Nationals on Friday.
Teng took the hill in the second inning after a perfect frame from opener Matt Gage. It was a good overall effort from the Giants' pitching staff, with Teng standing out with an efficient 64 pitches (42 strikes) during his outing. He rebounded from allowing five runs over 3.1 innings versus the Mets in his season debut last Saturday. Teng is likely to get another turn through the rotation, as Landen Roupp (elbow) is nearing a rehab assignment, which may consist of only one start. Should Teng get another turn, he's tentatively projected to face the Padres at home, though it's unclear whether he'll start or work behind an opener.

Giants' Kai-Wei Teng: Making first MLB start Saturday
Rotowire
Giants manager Bob Melvin said that Teng will start Saturday's game against the Mets at Citi Field, Susan Slusser of the San Francisco Chronicle reports.
Teng made four appearances out of the San Francisco bullpen in the opening month of the 2024 season, but he had pitched exclusively in the minors ever since then before the Giants called him up from Triple-A Sacramento on Friday. The right-hander had been limited to 1.2 innings in his most recent outing with Sacramento on July 25, but that was largely because the Giants wanted to keep him fresh for a potential start with the big club last week that ended up falling to Carson Whisenhunt. The Giants still had another opening in the rotation with Landen Roupp (elbow) recently landing on the injured list, so Teng will be needed for at least one start. Over 25 appearances (four starts) with Sacramento on the season, the 26-year-old righty owns a 3.67 ERA, 1.11 WHIP and 86:21 K:BB in 54 innings.

Giants' Kai-Wei Teng: Sent to minors camp
Rotowire
The Giants reassigned Teng to minor-league camp Wednesday, Justice delos Santos of The San Jose Mercury News reports.
Teng reached the big leagues for the first time in 2024 and made four ineffective relief appearances for the Giants before being non-tendered in November. The Giants re-signed him to a minor-league deal during the offseason, but since Teng is no longer a member of the 40-man roster, he'll likely face an uphill battle to resurface in the big leagues. Teng is expected to open the 2025 season at Triple-A Sacramento.

Giants' Kai-Wei Teng: Re-signs with San Francisco
Rotowire
The Giants re-signed Teng to a minor-league contract Nov. 29.
After being non-tendered last month, the right-hander has returned to the organization on a minor-league pact. Teng, 26, spent most of the 2024 season at Triple-A Sacramento, where he put up an 8.60 ERA and 1.81 WHIP over 75.1 innings.

Kai-Wei Teng: No contract from San Francisco
Rotowire
The Giants non-tendered Teng on Friday, Justice delos Santos of The San Jose Mercury News reports.
Teng was designated for assignment by the Giants on Tuesday, and the 25-year-old will now enter free agency. Teng spent most of the 2024 campaign with Triple-A Sacramento, where he struggled to an 8.60 ERA and 1.81 WHIP over 75.1 innings. He did manage to make his major-league debut in late March, and across four big-league outings he gave up 12 earned runs over 11 innings.
