Horwitz is out of the lineup for Monday's game against the Reds.

The left-handed-hitting Horwitz could end up settling into a full-time role with the Pirates eventually, but he'll take a seat for the series opener versus the Reds while lefty Nick Lodolo takes the hill for Cincinnati. After being reinstated from the injured list Saturday after he had been on the shelf all season while recovering from a procedure to alleviate pain in his right wrist, Horwitz started at first base in the final two games of the Pirates' weekend series with the Phillies, going 1-for-6.

Mervis is absent from the lineup for Monday's game against the Cubs.

Mervis has seen his playing time slip lately, as this is the fourth time over the Marlins' last 10 contests versus right-handed pitching that he's been out of the lineup. The 27-year-old is just 3-for-30 with a 44.1 percent strikeout rate across his last 12 games. Liam Hicks is in the designated hitter spot and batting seventh in Monday's series opener.

Long left Saturday's game for Triple-A Iowa due to a tight leg muscle, Tommy Birch of the Des Moines Register reports.

Long is slashing .367/.429/.533 with four home runs, two steals, a 9.5 percent walk rate and a 24.9 percent strikeout rate in his first 40 games at Triple-A. His 33.9 percent hard-hit rate is strong, but Long's .486 BABIP illustrates his good fortune in the early going. He hasn't been placed on Iowa's injured list and should be considered day-to-day for now.

Olson went 2-for-3 with a walk, two doubles, a run scored and an RBI in Sunday's win over the Red Sox.

The first baseman has reeled off three straight multi-hit performances, with four of his seven hits during that stretch going for extra bases including homers Friday and Saturday. Those were Olson's multi-hit efforts in May however, as he began the month slashing .173/.254/.365 with a 35.6 percent strikeout rate in 14 games. Despite that cold spell, he has respectable power numbers on the year with nine homers and 25 RBI in 47 contests, and he's more than capable to stretching his current heater straight through into June.

Wade went 1-for-3 with a triple and a run scored in Sunday's 3-2 win over the Athletics.

Wade entered as a pinch hitter and lined a leadoff triple to right field in the eighth inning before scoring the game-tying run. The first baseman has shown signs of turning things around after a slow start to the season, going 4-for-11 with two runs scored, an RBI, a triple, a double and a 2:2 BB:K across 13 plate appearances in his last five games. Wade is now slashing .165/.266/.281 with 14 RBI, 11 runs scored, 10 extra-base hits -- including one home run -- and a 17:31 BB:K across 140 plate appearances so far this season.

Busch went 2-for-4 with a stolen base and one RBI in Sunday's 6-2 win over the White Sox.

Busch has gone 8-for-29 (.276) over his last eight games, though he also has a 3:8 BB:K in that span. The first baseman contributed an RBI in the Cubs' sixth-inning rally that helped secure the win, and he also logged his first steal since April 20 versus the Diamondbacks. The first baseman has a career-high three steals already, so don't expect too much more in the speed department. Busch has added a .255/.355/.463 slash line, seven home runs, 25 RBI, 21 runs scored, eight doubles and a triple over 44 contests.

Steer is not in the Reds' lineup for Sunday's matchup versus the Guardians.

It's a rare day off for Steer, who started each of Cincinnati's previous 23 contests. He slashed .258/.320/.416 with three homers and three steals during that stretch and is currently riding a six-game hitting streak. With Steer out of the lineup Sunday, Connor Joe is getting a start at first base.

Freeman went 4-for-5 with two runs scored in Saturday's 11-9 loss to the Angels.

Freeman has a pair of four-hit efforts over his last six games. He's batting .441 (26-for-59) over 15 contests in May, adding eight extra-base hits and 17 RBI. The first baseman's .375 batting average ranks second to only Aaron Judge (.402) through Saturday's action. Freeman has added a fantastic 1.115 OPS, nine home runs, 34 RBI, 26 runs scored and no stolen bases through 35 games as he continues to receive treatment on his surgically repaired right ankle. While that ongoing recovery will prevent him from making much of an impact with speed, he's more than made up for it with his elite and dependable bat.

Hernandez went 2-for-2 with a solo home run, three walks and three total runs scored in Saturday's 11-9 loss to the Angels.

Hernandez has three multi-hit efforts over his last nine games, going 10-for-27 (.370) with two homers in that span. The utility player had drawn just seven walks over 101 plate appearances prior to Saturday, with his three-walk performance in this contest helping to lift his on-base percentage from .270 to .305. He's added seven homers, 16 RBI, 16 runs scored, two doubles and no stolen bases over 36 contests this season.

Horwitz went 0-for-2 on Saturday against the Phillies.

Horwitz was sidelined for the first seven weeks of the regular season and made his Pirates debut Saturday night. While he occupied the fifth spot in the order, the lefty-hitting Horwitz was pulled for a pinch hitter when lefty Matt Strahm took the mound. While Horwitz could have been pulled as he continues to build up stamina, it's possible this is an early sign that he'll be operating in a platoon at first base.
