Arraez went 3-for-4 with a double in Friday's 5-1 loss to the Mariners.

The Padres managed only eight hits in total, while the three batters behind Arraez in the order went a combined 0-for-11, so the 28-year-old's knocks didn't lead to any offense. Arraez is finding his groove in May, recording four three-hit performances in 13 games while producing a .298/.333/.368 slash line with six RBI and nine runs.

Naylor went 2-for-4 with a stolen base and a run scored in Friday's 8-0 win over the Rockies.

Naylor is now on an eight-game hitting streak, and the last three have been multi-hit efforts. He's 11-for-34 (.324) during the streak, adding three extra-base hits, four RBI and two steals. The first baseman has been at his best to begin his first season with Arizona, offering a high batting average with modest pop and some surprising speed. He's slashing .304/.370/.458 with eight steals, five home runs, 27 RBI, 23 runs scored and 11 doubles across 44 contests.

Contreras went 2-for-5 with two doubles, an RBI and three runs scored in Friday's 10-4 win over the Royals.

It was the sixth multi-hit showing of the month already for Contreras, who extended his on-base streak to 15 games in the process. During this streak, the veteran slugger is batting .365 (19-for-52) with four home runs, four doubles, 17 RBI and 12 runs scored. After moving away from the catcher position to first base for the Cardinals in 2025, Contreras has been able to appear in 44 of St. Louis' 45 games so far.

Olson went 2-for-4 with a solo home run in Friday's 4-2 win over Boston.

It was the first multi-hit game of the month for Olson, who did go deep for the fourth time in May. The All-Star first baseman has only four multi-hit efforts in 2025, and he's batting a mere .196 with seven RBI and seven runs scored over his last 56 at-bats. Olson is ninth in the National League in walks (29), however, and he figures to see a boost in RBI upside once Ronald Acuna (knee) is ready to make his season debut.

Mervis is out of the lineup for Friday's game against the Rays.

Mervis started the previous four games but will sit Friday after going 1-for-9 with a walk and three strikeouts during that stretch. Eric Wagaman will take over at first base for the series opener versus Tampa Bay.

The Pirates will activate Horwitz (wrist) from the 10-day injured list during their weekend series in Philadelphia, Noah Hiles of the Pittsburgh Post-Gazette reports.

He will not be activated Friday, perhaps because the Phillies are starting left-hander Ranger Suarez. Instead, Horwitz will return from the IL later this weekend. Horwitz has been working his way back from February surgery to repair an extensor tendon in his right thumb that was causing pain in his wrist. The 27-year-old posted just a .677 OPS in 13 rehab games, but he was heating up at Triple-A Indianapolis, going 6-for-13 with one home run over his last three contests. Horwitz is set to serve as the Pirates' primary first baseman.

Villar went 1-for-2 with a run scored and two walks in Wednesday's 8-7 loss to the Diamondbacks.

Villar started at first base Wednesday, collecting two free passes for the first time this season. Additionally, the 28-year-old hit an infield single in the fourth inning before coming around to score his first run since April 22. The infielder has made five appearances in May, slashing .222/.462/.222 with a 3:2 BB:K across 13 plate appearances.

Triolo went 1-for-4 with a two-run home run Wednesday against the Mets.

Triolo recorded his first home run of the season Thursday and has at least one hit in five of his last six games. He's scored four runs in that span and has surprisingly tallied four total extra-base hits. Despite the slight uptick in production, Triolo is hitting just .167/.233/.308 across 87 plate appearances.

Gorski went 1-for-4 with a two-run home run Wednesday against the Mets.

Gorski was in the lineup rarely with Derek Shelton managing the Pirates, but he has started five of six games since Don Kelly took over. He's struck out nine times in 19 plate appearances in that span while collecting only four hits, though he did manage a two-run homer in the second inning Wednesday, providing what proved to be the winning runs for Pittsburgh.

Steer went 2-for-4 with a solo home run and a double during Wednesday's 4-2 loss to the White Sox.

Steer broke the Reds' scoring slump in the seventh inning by swatting a solo home run off Davis Martin. The long ball was Steer's fourth of the campaign. The 27-year-old also notched a double for a third straight contest. On the year, Steer is slashing .199/.271/.333 with 21 runs scored and 12 RBI.
