The Rockies recalled Castano from Triple-A Albuquerque to serve as the 27th man for Sunday's doubleheader against the Mets.

Castano was claimed off waivers from Seattle on Tuesday and will now receive his first look in the majors with his new organization. The right-hander has allowed one earned run over 7.1 innings at Triple-A between Albuquerque and Tacoma.

Imai (arm) is slated to begin a minor-league rehab assignment with Double-A Corpus Christi on Tuesday, Chandler Rome of The Athletic reports.

Imai landed on the IL due to right arm fatigue April 13. Imaging came back clean, and the Japanese hurler has been building up his workload since, which included him tossing 45 pitches in a bullpen session Friday. Imai will now progress to game action with Corpus Christi and appears to be on track to rejoin the Astros in the first half of May.

Tampa Bay optioned Martin to Triple-A Durham on Sunday, Ryan Bass of Rays.tv reports.

Martin got his first call-up to the majors Monday and logged three appearances with the big-league club, allowing three earned runs on six hits while posting a 4:1 K:BB over 4.1 innings. He's headed back to Triple-A to make room on the active roster for Casey Legumina, who the Rays acquired in a trade with Seattle on Friday.

Miller (oblique) struck out six and gave up one hit and one walk over three scoreless innings Friday in a rehab start with High-A Everett.

After recording just five outs on 33 pitches in his first rehab appearance with Triple-A Tacoma on April 18, Miller moved down a couple levels for his second minor-league start and delivered a much more efficient performance. During Friday's outing, he spotted 35 of his 47 pitches for strikes and induced eight swings and misses while sporting a fastball that sat between 96 and 98 miles per hour. Per MLB.com, Miller is tentatively trending toward a return from the 15-day injured list May 17, which suggests he'll need three more rehab starts prior to being activated. The right-hander has been on the shelf all season while recovering from a left oblique strain.

Rea (3-1) took the loss against the Dodgers on Saturday, allowing six runs on six hits and four walks while striking out four batters over 3.1 innings.

Rea got through two scoreless frames before giving up a two-run homer to Max Muncy in the third inning. Things went even further south for the righty in the fourth -- he retired the first hitter he faced, then allowed four straight batters to reach base, all of whom eventually came around to score (two after his departure). Rea hurt himself by issuing four free passes in the loss after handing out no more than two walks in any of his first five outings. He came into Saturday on a three-game win streak and having given up no more than three earned runs across any of his first five appearances, so he'll look to return to that form in what's projected to be a home start against Arizona next week.

Misiorowski didn't factor into the decision Saturday against the Pirates, allowing three runs on six hits and a walk across six innings. He struck out nine.

Misiorowski has fanned at least nine in four of his six starts this season, and he continues to be a good source for punchouts even if he's not pitching super deep into games. The right-hander has worked at least six innings just twice in 2026, but he's yet to allow more than three earned runs in any outing this year. Misiorowski will carry his 3.31 ERA and 51:15 K:BB across 32.2 innings into a likely matchup against the Nationals on the road next weekend.

Flaherty (0-2) took the loss against Cincinnati on Saturday, surrendering six runs on five hits and two walks while striking out four batters over two innings.

Flaherty was staked to a 1-0 lead after half an inning, but he quickly fell behind by yielding two homers for four total runs in the bottom of the frame. The Reds got to him for another long ball in the second, and Flaherty wasn't allowed to return to the mound for the third. The three long balls were a season worst for Flaherty, who had given up just one homer over his five starts prior to Saturday. It's been an up-and-down campaign, as Flaherty holds a 5.33 ERA despite yielding one or no earned runs in three of his six outings. His next start is projected to be a home matchup versus Texas.

Singer (2-1) earned the win over Detroit on Saturday, allowing two runs on eight hits and no walks while striking out three batters over 5.1 innings.

Singer's outing didn't start out well, as he gave up a leadoff homer to open the contest. However, he was able to get through 5.1 innings with just one other run on his ledger, which also came via a solo homer. Beyond those two long balls, the other six hits Singer allowed were all singles, and he minimized additional damage by not walking any batters. The right-hander fell short of notching a third straight quality start, but he seems to be turning things around after posting a 7.71 ERA through his first three starts of the campaign.

Keller didn't factor into the decision Saturday against the Brewers, allowing three runs on five hits and two walks while striking out six across five innings.

Keller tossed 60 of his 93 pitches for strikes and ended just three outs away from recording a quality start -- a feat he's accomplished in four of his six outings in 2026. The six strikeouts were also a season-high mark for the right-hander, who has given up three or fewer runs in five of his first six starts. Keller has a 3.18 ERA across 34 innings this season, and he lines up for a road matchup with the Red next weekend.

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.
