Santillan struck out one over one scoreless inning to earn a hold in Saturday's 2-0 win over the Rangers.

Santillan threw a 1-2-3 eighth inning, setting down the top of Texas' order, to earn his third hold of the season. The right-hander's velocity remains noticeably down from 2025, but it hasn't impacted his effectiveness. Santillan's given up one hit and four walks while striking out seven over five scoreless innings. He's been used in the eighth inning in all five of his appearances.

With Cade Horton (forearm) set to land on the injured list, Assad is an option to get promoted from the minors and fill his rotation spot, Jordan Bastian of MLB.com reports.

Horton departed Friday's contest after only an inning of work due to right forearm discomfort, and he will be examined more fully to determine the extent of the injury. Following a rainout Saturday, the Cubs don't have to worry about Horton's spot in the rotation again until Wednesday. Assad is a candidate to get the call from Triple-A Iowa, though it appears to be more likely that Ben Brown or Colin Rea moves over from the bullpen and into the rotation. Even if Assad isn't needed right away, he could be next in line if any other Chicago pitchers go down.

Barrosa started in left field and went 0-for-3 in Saturday's 2-1 loss to Atlanta.

With Jordan Lawlar (wrist) out for the next six-to-eight weeks, Barrosa is likely to share left field with Tim Tawa, who started there Friday. That arrangement should continue until Lourdes Gurriel (knee) is ready to return and play defense. Barrosa has made three starts so far and is 2-for-9 with two doubles and a run scored.

Martin is expected to be called up from Triple-A Iowa to take the roster spot of Cade Horton (forearm), who is set to land on the injured list, Jordan Bastian and Jason Foster of MLB.com report.

After Horton departed Friday's contest with right forearm discomfort, Martin joined the Cubs at Progressive Field in Cleveland on Saturday, but the game was rained out and Chicago didn't have to make any roster moves. The Cubs get a 27th man for Sunday's doubleheader, but Martin may stick around into next week. The lefty reliever has been in the organization since 2021 but has yet to make his MLB debut. He would likely fill a middle relief role, with one of Ben Brown or Colin Rea expected to move from the bullpen into the rotation with Horton out.

Del Castillo served as the designated hitter and went 0-for-3 in Saturday's 2-1 win over Atlanta.

Del Castillo made his season debut after the Diamondbacks activated him off the IL on Friday. He batted fifth in the order, which could provide RBI opportunities if he sticks in that spot when he's in the lineup. Del Castillo is expected to get regular turns at DH against right-handers, as was the case Saturday, until Pavin Smith (elbow) is healthy.

Arizona manager Torey Lovullo said Saturday that a decision whether to activate Kelly (back) when eligible will be announced Sunday, Alex Weiner of Arizona Sports reports. The right-hander can be activated April 8.

Kelly is fresh off a 72-pitch outing at Triple-Reno on Friday and responded well the following day. His activation would force an adjustment to the existing five-man rotation. The Diamondbacks could move a current starter with relief experience to the bullpen -- Michael Soroka or Ryne Nelson -- or option Brandon Pfaadt to the minors.

Phillies manager Rob Thomson said Saturday that Wheeler (shoulder) will continue his rehab assignment Wednesday with Triple-A Lehigh Valley and will make another minor-league start after that, Matt Gelb of The Athletic reports.

Wheeler struggled in his second rehab start with Lehigh Valley on Friday, allowing five runs on four hits and two walks while striking one batter over three innings. His four-seamer averaged 92.7 mph, and Philadelphia will give him at least two more starts to build up in the minors after he threw 49 pitches Friday. That puts a possible return to the major leagues around April 18 or 19, depending on how Wheeler fares as he completes his recovery from venous thoracic outlet syndrome surgery.

Taylor went 2-for-3 with a three-run home run and an additional RBI in a 9-0 win against the Giants on Saturday.

Taylor began the game on the bench, but he was called upon to pinch hit for Jared Young in the fifth inning. That decision proved to be wise for the Mets, as Taylor blasted a three-run homer on the fifth pitch he saw and later added an RBI single. This was a much-needed performance by Taylor, who entered the game 0-for-9 through four contests. Taylor could see more opportunities moving forward if Juan Soto, who left Friday's game due to a minor right calf strain, needs to miss more time.

Roupp (1-1) took the loss against the Mets on Saturday, allowing seven runs (five earned) on seven hits and one walk while striking out seven batters over 4.2 innings.

The seven punchouts were useful for fantasy managers who deployed the hurler, but there were few (if any) other positives to take away from Roupp's performance. His outing was particularly disappointing given the strong six innings of shutout ball he tossed against San Diego in his season debut Monday. Roupp was similarly up-and-down last season -- he had six outings of zero runs allowed and five of four or more runs permitted over 22 regular-season starts -- so consistency seems to be his biggest issue. He'll try to get back on track in his next start, which is tentatively scheduled to come in Baltimore next week.

Holmes (2-0) earned the win over San Francisco on Saturday, allowing three hits and walking two batters while striking out four over seven scoreless innings.

Holmes allowed exactly one baserunner in each of his first four innings and then went into shutdown mode. Over his final three frames, he yielded just one baserunner (a single). Holmes wasn't overpowering, getting just seven whiffs and four punchouts, but he picked up his second win and first quality start of the campaign. Through two outings, he has allowed just two runs across 12.2 frames while posting a 9:5 K:BB.
