Manager Dave Roberts said Wednesday that Yamamoto (triceps) is on track to return from the 60-day injured list and rejoin the Dodgers rotation sometime in mid-September, Jack Harris of the Los Angeles Times reports.

Roberts noted that he was impressed with Yamamoto's stuff during his two-inning simulated game Wednesday, and the right-hander will get stretched out to three innings when he throws another sim game next week. Assuming everything goes smoothly, he will then head out on a minor-league rehab assignment to continue building up to a starter's workload.

Manager Dave Roberts said Wednesday that Glasnow (elbow) has yet to begin playing catch, Jack Harris of the Los Angeles Times reports.

The skipper added that Glasnow likely won't be activated once he's eligible to come off the injured list Aug. 31, but the team's concern is still relatively low. A clearer return timeline for the 30-year-old right-hander may emerge once he's able to begin a throwing program.

Wicks (oblique) struck out four while allowing one hit and no walks over four scoreless innings in his rehab start Tuesday with Triple-A Iowa.

After being tagged for 10 earned runs while walking four batters in 3.2 innings over his first two rehab starts with Iowa, Wicks showed much improved command and control Tuesday while informing the Cubs afterward that he "felt great" during the outing, per Ryan Herrera of AllCHGO.com. After building up to 53 pitches Tuesday, Wicks will need at least one more outing in the minors to get fully stretched out before he returns from the 60-day injured list. Kyle Hendricks would seem to be most at risk of losing his spot in the rotation once Wicks is activated.

German allowed three hits and four walks over six scoreless innings in a no-decision Wednesday against the Rangers. He struck out four.

Making his first start this season, German was excellent, blanking the Rangers over six frames despite allowing at least one baserunner in five frames. The 31-year-old right-hander has allowed just two runs through 12 innings this year with the Pirates, posting a 1.00 WHIP with eight strikeouts. However, with Jared Jones (lat) nearing a return, German figures to head back to a swingman role in Pittsburgh.

Manaea allowed three runs on three hits over seven innings in a no-decision Wednesday against the Orioles. He struck out nine.

Manaea got off to a stellar start Wednesday, setting down the first 17 batters he faced. However, he hit Jackson Holliday with a pitch with two outs in the sixth inning before surrendering a two-run homer to Austin Slater, Baltimore's first hit of the game. Manaea has now gone seven innings in four of his last five outings, pitching to a 2.61 ERA in that span (31 innings). Overall, the left-hander is 9-5 on the year with a 3.48 ERA, 1.17 WHIP and 138:52 K:BB across 137 innings. Manaea is currently lined up for a road matchup with the Diamondbacks early next week.

Diamondbacks manager Torey Lovullo said Wednesday that Nelson is tentatively scheduled to start Friday's game against the Red Sox, Steve Gilbert of MLB.com reports.

Nelson will be available in relief Wednesday in Miami, if needed, but the Diamondbacks seemingly prefer to stay away from him so that he can take the hill Friday. Though Lovullo has previously stated that Arizona eventually plans to condense to a five-man rotation, Nelson has made it tough on the Diamondbacks to demote him to the bullpen. He's posted a 2.73 ERA and 55:11 K:BB over 56 innings since the beginning of July, and another strong outing Friday could prompt Arizona to keep him in the fold for another turn through the rotation.

Yamamoto (triceps) will throw a two-inning simulated game Wednesday, per MLB.com.

This will be Yamamoto's second sim game since he landed on the injured list in mid-June. In his first, the Japanese hurler threw 17 pitches in St. Louis on Aug. 16. Yamamoto is expected to follow Wednesday's simulated game with a three-inning sim game before heading out on a minor-league rehab assignment. He could return to the Dodgers' rotation in early September.

Assad (6-3) picked up the win Tuesday, allowing one run on six hits and a walk over 5.2 innings in a 3-1 victory over the Tigers. He struck out seven.

The seven Ks were the most for the right-hander since June 17, and Assad tossed 59 of 95 pitches for strikes as he fell just short of his fifth quality start of the season. He has yet to give up more than three runs in an outing since he recovered from a forearm strain and rejoined the Cubs' rotation just before the All-Star break, delivering a 3.30 ERA over his last 30 innings despite a worrying 20:17 K:BB and 1.60 WHIP. Assad will try to keep walking that tightrope in his next start, which lines up to come on the road this weekend in Miami.

Jones (lat) struck out 10 and allowed one hit and no walks over five scoreless innings Tuesday in his rehab start with Triple-A Indianapolis.

While making the third start of his rehab assignment for Indianapolis, Jones showed that he's likely ready to make his return from the 15-day injured list. The lone hit he allowed on the night was an infield single, and Jones generated 15 swings and misses among his 73 pitches (53 strikes) while throwing a fastball that averaged 97.6 miles per hour, per Jack McMullen of JustBaseball.com. Assuming the Pirates are comfortable with how Jones is feeling physically coming out of the rehab start, he could be activated from the 15-day injured list and rejoin the big-league rotation as soon as Monday's series opener versus the Cubs. Jones has been on the shelf since July 4 with a Grade 2 right lat strain.

Keller (11-7) picked up the win Tuesday in a 4-0 victory over the Rangers, scattering three hits over seven-plus scoreless innings. He struck out nine without walking a batter.

After getting hammered for 15 runs in 12 innings over his last two trips to the mound, Keller was razor-sharp Tuesday, firing 73 of 98 pitches for strikes and retiring the first 11 batters he faced. All three hits off the right-hander were singles, and none of the runners even managed to get to second base. The quality start was Keller's 13th of the year, while the nine strikeouts tied his season high. He'll take a 3.76 ERA, 1.21 WHIP and 134:40 K:BB through 148.1 innings into his next outing, which lines up to come at home early next week against the Cubs.
