Casas underwent successful surgery Sunday to repair the ruptured patellar tendon in his left knee, Chris Cotillo of MassLive.com reports.

The 25-year-old suffered the injury during Friday's 6-1 win over the Twins, and the organization didn't waste much time sending him in for the surgery. Casas doesn't have an official timeline for his return, but he's expected to miss the rest of the 2025 season while going through his recovery and rehab programs. Romy Gonzalez has started at first base in both of the two games since Casas went down with the knee injury.

The White Sox designated Dalbec for assignment on Sunday.

The 29-year-old was added to the big-league roster April 21 and appeared in seven games during his time in the majors, going 4-for-18 with three walks and six strikeouts. Dalbec could return to Triple-A Charlotte if he goes unclaimed on waivers.

Mervis is out of the lineup for Sunday's game against the Athletics.

With southpaw JP Sears on the hill for the Athletics, the left-handed-hitting Mervis will retreat to the bench. The Marlins will give Eric Wagaman a start at first base while Mervis sits.

Soderstrom is out of the lineup for Sunday's game against the Marlins.

Soderstrom will get his first day off of the season, in the midst of a rough patch at the dish. After slugging nine home runs in the Athletics' first 19 games, Soderstrom has gone without a long ball over the ensuing 15 contests and is slashing .228/.286/.281 with three doubles, one stolen base, six RBI and five runs during that stretch, a downturn that has coincided with a shift to the outfield to accommodate rookie Nick Kurtz. Soderstrom will give up his spot in the lineup Sunday to Miguel Andujar, who will start in left field and bat cleanup.

Triolo will start at shortstop and bat eighth in Sunday's game against the Padres.

Triolo initially served as a utility infielder upon returning from the injured list April 16, but he's been thrust into an everyday role in the middle infield. He'll pick up his sixth consecutive start and his fourth in a row at shortstop, which should be his primary home until Isiah Kiner-Falefa (hamstring) is ready to return from the IL.

Torkelson went 1-for-3 with a solo home run in Saturday's 5-2 loss to the Angels.

Torkelson hit his team-leading 10th home run of the season in the eighth inning as Detroit mounted an unsuccessful comeback attempt. The 25-year-old has seen his average tumble a bit as he's batting just .125 over his last 10 games, but he's gone deep three times during that time and his power remains his top fantasy asset.

Freeman went 3-for-5 with a home run, two total runs and four total RBI in a 10-3 victory against Atlanta on Saturday.

Freeman knocked in a run with a single in the fourth inning and later broke the game open with a three-run blast to center field in the eighth. In the process, the veteran first baseman extended his hitting streak to eight games -- a stretch during which he's batting a sizzling .483 (14-for-29) with two homers, 10 RBI and a 6:4 BB:K. Freeman has dealt with a lingering ankle injury at times early in the season, but he's been as potent as ever with a .338/.422/.662 slash line, six home runs and 21 RBI through 22 games.

Biggio went 1-for-3 with a solo home run in a 4-0 win against Baltimore on Saturday.

Offense was at a premium in the rain-delayed contest, and Biggio provided a key run with his 389-foot solo shot in the fifth inning. It was the first long ball of the season for the veteran infielder, who has struggled to a .191/.321/.255 slash line through 57 plate appearances this season. The poor numbers have impacted Biggio's playing time and have made him a non-factor in almost all fantasy formats.

Gonzalez went 3-for-4 in Saturday's 4-3 loss to the Twins.

Gonzalez got the start at first base Saturday and belted three singles while batting in the sixth spot in the lineup. He's expected to see the bulk of starts at first base in the short term after Triston Casas ruptured his left patellar tendon in Friday's game, with Abraham Toro providing depth at the position. How Gonzalez plays over the coming days and weeks will play a factor in how the Red Sox address the position, either internally through the farm system or externally via trade, per Ian Browne of MLB.com.

Harper went 0-for-4 with a walk in Saturday's 7-2 win over the Diamondbacks.

Harper's recent slump continued Saturday, as he's now without a home run in 13 consecutive games. He has only four extra-base hits during this span and is batting just .176 (9-for-51) with five RBI, four runs scored and two stolen bases since April 19. Harper has reached base safely in 11 of these 13 outings, so fantasy managers should remain patient while the All-Star first baseman looks to get back on track.
