Kolek (4-5) allowed two runs on four hits and three walks over six innings to pick up the win Sunday at St. Louis. He struck out two.

The San Diego righty limited the Cardinals offense to just one extra-base hit -- an Alec Burleson two-run homer in the sixth -- as he looked sharp in this 98-pitch appearance. This marks the fourth quality start of the season for Kolek, who should remain in the rotation for another turn given this performance. He'll carry a 4.18 ERA, 1.31 WHIP and 56:26 K:BB across 79.2 frames into a rematch with the Cardinals at home next weekend.

Ober (hip) is likely to return from the 15-day injured list to make his next start with the Twins sometime this week, Aaron Gleeman of The Athletic reports.

The right-hander made his second rehab start with Triple-A St. Paul on Friday and allowed one run across five innings while building up to 65 pitches, setting him up to rejoin Minnesota's rotation. Ober has been sidelined nearly a month due to a hip impingement and could have some minor workload limitations in his first outing back in the majors. The 30-year-old struggled in his last five starts before landing on the shelf with a 9.00 ERA and 14 home runs allowed over 30 innings.

The Royals placed Bubic (shoulder) on the 15-day injured list Sunday after he was diagnosed with a left rotator cuff strain.

Bubic complained of shoulder stiffness after Saturday's start, and the Royals quickly determined that he was dealing with an injury to his rotator cuff. According to Anne Rogers of MLB.com, manager Matt Quatraro said that Bubic will undergo further testing, but the left-hander is a good bet to miss more than the minimum 15 days. The loss of Bubic -- who earned his first All-Star nod after compiling a 2.55 ERA and 1.18 WHIP with 116 strikeouts in 116.1 innings over his first 20 starts this season -- is a devastating blow to a Kansas City rotation that has been missing Cole Ragans (shoulder) since early June.

Miller is transitioning to a relief role with Triple-A Oklahoma City, Fabian Ardaya of The Athletic reports.

It seems like forever ago that Miller was among the most promising young starters in the game, but after an impressive 2023 rookie campaign with the Dodgers he lost his major-league role in 2024 and has given up seven earned runs over just five frames across two appearances with the big club this season. Miller also hasn't been very good with OKC this year, posting a 5.58 ERA, 1.64 WHIP and 57:49 K:BB over 69.1 innings spanning 16 outings (14 starts). Converting Miller to a relief role could provide Los Angeles with a high-leverage option late in the campaign if he does well.

Bubic said after Saturday's 6-4 loss to the Guardians that "physically something's not right," adding that he's been pitching through shoulder stiffness "for a good portion of the season," Anne Rogers of MLB.com reports.

The left-hander's fastball has averaged 92.1 miles per hour this season, but he sat at 90.2 mph during his start Saturday while tying a season high with four walks over just 2.2 innings. Bubic will likely be evaluated throughout the week, and his availability for his next turn through the rotation -- which tentatively lines up for next weekend in Toronto -- is firmly up in the air. Regardless of whether he's available for his next start, the injury is worth monitoring since Bubic's workload this season (116.1 inning) is already approaching his career high of 130 innings from 2021.

Kolek is slated to start Sunday's game against the Cardinals in St. Louis.

Kolek will make another turn through the San Diego rotation after he was recalled from Triple-A El Paso on Tuesday to fill the vacant fifth starter spot. Taking the hill for the big club for the first time since July 5, Kolek was dealt the loss against the Marlins after giving up three earned runs on eight hits and one walk over 5.2 innings. In 13 starts with San Diego this season, Kolek has gone 3-5 with a 4.28 ERA, 1.32 WHIP and 54:23 K:BB across 73.2 innings.

May is slated to start Sunday's game against the Red Sox at Fenway Park.

For the first time all season, May worked out of the bullpen in his most recent appearance against the Twins on Monday, when he tossed 4.2 scoreless frames in bulk relief behind Shohei Ohtani, who was limited to three innings. Ohtani isn't scheduled to pitch again until Wednesday, so the Dodgers will return May to his traditional starting role for the series finale in Boston. Over his 17 starts this season, May has gone 5-6 with a 4.96 ERA, 1.35 WHIP and 88:40 K:BB across 94.1 innings.

Atlanta placed Holmes on the 15-day injured list Sunday due to right elbow inflammation.

The right-hander exited his start in Saturday's 6-5 loss to the Rangers after four innings due to the injury, and he'll be sidelined for at least the next couple of weeks and potentially longer. Atlanta now has all five members of its Opening Day rotation on the IL, with Holmes joining Chris Sale (ribs), Spencer Schwellenbach (elbow), Reynaldo Lopez (shoulder) and AJ Smith-Shawver (elbow) on the shelf.

Arrighetti (thumb) threw 62 pitches in his rehab appearance Saturday with Double-A Corpus Christi.

Arrighetti covered 3.1 innings, allowing three runs (two earned) on four hits and one walk while striking out two. He was sharper in his first rehab outing, though he did progress from 43 pitches. Arrighetti will make at least one more rehab appearance before being activated.

Smith (ankle) threw a 55-pitch live batting practice session Saturday, Scott Merkin of MLB.com reports. "Yeah, it felt good to be back on the bump," the right-hander said after the session. "The soreness is pretty much gone. I threw a bullpen the other day and it felt pretty good. Today, I didn't feel anything."

Smith faced a few big-league hitters and simulated throwing three innings. He'll set to throw another bullpen session, and the White Sox are hoping he'll be ready to rejoin the rotation before the end of the month without needing a rehab assignment.
