Holmes is expected to be placed on the injured list due to right elbow tightness Sunday, David O'Brien of The Athletic reports.

Holmes threw 81 pitches over four innings in a start against Texas on Saturday, giving up four runs on six hits and two walks with two strikeouts. After the game, manager Brian Snitker said the right-hander dealt with elbow tightness during the outing and will be placed on the injured list to get checked out. Holmes' injury is another in what has been a devastating season for the team's rotation -- Chris Sale (ribs), Spencer Schwellenbach (elbow), Reynaldo Lopez (shoulder) and AJ Smith-Shawver (elbow) are all also currently on the IL.

Senzatela (4-14) took the loss against the Orioles on Saturday, allowing six runs on six hits and two walks with three strikeouts over four innings.

Senzatela allowed five of his six runs via the long ball and gave up eight hard-hit balls while generating just five whiffs on 77 pitches. It marked the sixth time in 21 starts the 30-year-old has surrendered multiple homers, and he's now allowed six or more earned runs on five occasions. He'll carry a 6.68 ERA, 1.84 WHIP and 55:36 K:BB across 102.1 innings into a home matchup with the Pirates next weekend.

Heaney (5-9) earned the win against the Diamondbacks on Saturday, allowing two hits and no walks with four strikeouts over five innings.

Heaney threw 47 of 71 pitches for strikes, generating 10 whiffs and limiting the Diamondbacks to just three hard-hit balls. It was a much-needed effort for the 34-year-old, who had allowed 14 earned runs over nine innings in his previous three starts. He'll take a 4.79 ERA, 1.27 WHIP and 78:35 K:BB across 107 innings into a road matchup with the Rockies next weekend.

Horton (4-3) earned the win against the White Sox on Saturday, allowing four hits and one walk while striking out three across 6.1 scoreless innings.

It was another strong start for Horton, who limited the White Sox to just five baserunners while tossing 84 pitches (56 strikes). The 2022 first-round pick has yielded zero runs in three of his last four starts, which now has him at a 3.67 ERA and 1.31 WHIP across 68.2 innings this season. It was Horton's first win since June 3 against the Nationals, and he'll look to make it two in a row in his next start, which is slated for next weekend at home against the Orioles.

Kelly (9-6) took the loss against the Pirates on Saturday, allowing two runs (one earned) on six hits and one walk with three strikeouts over 6.2 innings.

Kelly gave up a two-run homer in the second inning, and that proved to be all the Pirates needed as the Diamondbacks were shut out. The 36-year-old still logged his fourth quality start in five July outings, allowing just eight earned runs over 30.2 innings during that stretch. He'll take a 3.22 ERA, 1.06 WHIP and 121:38 K:BB across 128.2 innings into a road matchup with the Athletics next weekend.

Megill (elbow) threw a bullpen session Thursday and is scheduled for another Sunday, Laura Albanese of Newsday reports.

Megill was placed on the 15-day IL with a sprained elbow June 17 and was transferred to the 60-day IL on July 8. Mets manager Carlos Mendoza said Saturday that the righty hurler is trending in the right direction, though Megill isn't eligible to be activated until mid-August.

Suarez (8-4) picked up the win Saturday, allowing one run on seven hits and one walk over 5.2 innings in a 9-4 victory over the Yankees. He struck out eight.

The southpaw fell short of his 12th quality start of the season, but Suarez racked up a whopping 38 called or swinging strikes among his 108 pitches (71 total strikes) as he collected his first win in July. Suarez has given up one run or fewer in six of his last eight outings, a stretch in which he's delivered a 2.50 ERA, 1.21 WHIP and 52:16 K:BB over 50.1 innings. He'll look to stay sharp in his next trip to the mound, which lines up to come at home next weekend against the Tigers.

Nola (ankle/rib) will begin a rehab assignment at Triple-A Lehigh Valley on Thursday, Charlotte Varnes of The Athletic reports.

Nola began facing live hitters last Saturday, and the plan is for him to build up to around 60 pitches during his return to game action Thursday. The 32-year-old righty has been on the IL since late May, so he'll almost certainly require an additional start or two beyond Thursday before rejoining Philadelphia's rotation.

Sheehan (2-1) picked up the win Friday, giving up two runs on three hits and two walks over five innings in a 5-2 victory over the Red Sox. He struck out five.

The 25-year-old righty bounced back nicely from a rough outing last Saturday against the Brewers, tossing 47 of 78 pitches for strikes in this one as he completed five innings for the second time in five big-league outings this season. Sheehan has been an effective stop-gap for the Dodgers, posting a 4.22 ERA, 1.27 WHIP and 21:7 K:BB over 21.1 innings, but he may be headed back to Triple-A Oklahoma City, as Blake Snell (shoulder) will likely need only one more rehab start before rejoining the rotation.

Walker came away with a no-decision in Friday's 12-5 win over the Yankees, giving up three runs on six hits -- including three home runs -- over 5.2 innings. He struck out three without walking a batter.

Solo shots by Cody Bellinger in the first inning, Austin Wells in the second and Giancarlo Stanton in the sixth accounted for all the damage off Walker, who got the hook after 83 pitches (55 strikes), one out short of his second quality start of the season. The veteran righty has served up five homers in his last two starts, but he's allowed just six runs total in those outings and will likely continue to hold down a rotation spot until Aaron Nola (ribs) is ready to return. Walker lines up to make his next trip to the mound on the road next week against the White Sox.
