Locklear started at first base and went 0-for-4 in Friday's 3-0 win over the Dodgers.

The news that Pavin Smith (quadriceps) landed on the 10-day injured list Friday opens the door for Locklear to see more playing time. The righty-hitting first baseman was in Friday's starting nine against a left-hander (Blake Snell), which is normal, and manager Torey Lovullo told Alex Weiner of Arizona Sports that Locklear's role will expand for him to face certain right-handers as well. Utility infielder Ildemaro Vargas, a switch hitter, may also play against righties.

Mountcastle went 3-for-5 with two doubles, four RBI and one run scored in Friday's 15-8 loss to the Giants.

Mountcastle had Robbie Ray's number, delivering all three hits over the first five innings of the game. Since returning from a Grade 2 hamstring injury, Mountcastle has gone 21-for-73 (.288) with five extra-base hits and 12 RBI over 19 contests. The first baseman has reclaimed a starting role in the lineup and is up to a .258/.294/.365 slash line with four homers, 16 doubles, 27 RBI, 26 runs scored and three stolen bases over 71 games this season.

Mayo went 1-for-4 with a solo home run in Friday's 15-8 loss to the Giants.

Since his homer Aug. 15 versus the Astros, Mayo had gone just 4-for-39 (.103) with a 3:16 BB:K over 10 contests. The infielder was able to snap his power drought Friday, but he hasn't posted a multi-hit effort since Aug. 6 versus the Phillies. Mayo is up to six homers, 20 RBI, 20 runs scored, one stolen base and a .189/.268/.335 slash line over 60 contests this season. While his playing time has been steady this month, the lack of reliable production makes the 23-year-old tough to roster in redraft formats.

Smith went 2-for-3 with a home run, four total RBI and one walk in Friday's 15-8 win over the Orioles.

Smith continues to play well in a strong-side platoon role at first base. He's 22-for-71 (.310) with six extra-base hits and 15 RBI over 21 contests in August, though his homer Friday was his first since Aug. 2. The first baseman is up to a .284/.339/.414 slash line with four homers, 27 RBI, 21 runs scored, 10 doubles and two stolen bases across 54 games. Smith will likely continue to share first base with Rafael Devers, who is usually at the position when the Giants are facing a left-handed pitcher.

Vaughn went 3-for-5 with two RBI and a run scored during the Brewers' 7-2 win over the Blue Jays.

Vaughn helped blow the game open in the sixth inning with an RBI single off Shane Bieber, and the former tacked on another run in the seventh with a single to right field that brought William Contreras home. Since the All-Star break, Vaughn has an .818 OPS with seven home runs and 30 RBI in 164 plate appearances.

Busch went 2-for-5 with a solo home run and an additional run scored in an 11-7 win over the Rockies on Friday.

Busch added his 26th homer of the campaign as he aims to post the first 30-homer season of his career. The first baseman now has at least one hit in nine of his last 11 outings, and he's been a steady contributor for the Cubs and fantasy managers in 2025. Across 488 plate appearances, Busch is slashing .262/.340/.499 with 19 doubles, 76 RBI, 61 runs scored and four stolen bases.

Kurtz was removed from Friday's game against the Rangers with right oblique soreness, Martin Gallegos of MLB.com reports.

After scoring from second base during the third inning, Kurtz was replaced in the field to begin the fourth frame. The severity of his injury remains unknown, though the A's may play it safe and hold the rookie slugger out for a game or two. If that ends up being the case, Tyler Soderstrom and Brett Harris would be in play to start at first base.

Alonso went 3-for-6 with a two-run homer and an additional run scored during Friday's 19-9 win over the Marlins.

Alonso gave the Mets a 7-0 lead in the second inning with a two-run blast to right field. He is now up to 31 home runs on the season, which is second on the Mets behind Juan Soto (33) and ninth in the majors. Alonso has logged at least one hit in each of his last five games and has slashed .306/.342/.622 with nine homers and 29 RBI in 120 plate appearances since Aug. 1.

Freeman (neck) will start at first base and bat third Friday against the Diamondbacks, Jack Harris of the Los Angeles Times reports.

A stinger in Freeman's neck forced him onto the bench for Wednesday's contest, but after an additional day off for the team Thursday, he's ready to rejoin the starting nine. The veteran first baseman has been as good as ever this month, slashing .319/.379/.626 with seven homers, 19 RBI, 15 runs scored and two stolen bases through 103 plate appearances since the start of August.

The White Sox recalled Elko from Triple-A Charlotte on Friday.

The 26-year-old was sent to Charlotte in early August after recovering from a knee sprain but will receive another look in the majors with Miguel Vargas (hand) landing on the IL. Elko has a .145/.209/.355 slash line with four homers in his first 20 MLB games this season.
