Mervis isn't in the lineup for Saturday's game against the White Sox.

Make it back-to-back days that Mervis has taken a seat against a right-handed starter. It's still unclear at his point if the 27-year-old has fallen down the Marlins' depth chart, but he'll step aside Saturday while Ronny Simon serves as Miami's DH against Chicago's Shane Smith.

Gonzalez (back) was placed on the 10-day injured list Saturday.

Gonzalez began dealing with the back issue Wednesday and has sat two games since. The move is retroactive to May 8, though Gonzalez's timeline to return is unclear. Gonzalez's injury also makes Boston's first base situation even more dire, with Abraham Toro projected to see the majority of playing time at the position.

The White Sox selected Elko's contract from Triple-A Charlotte on Saturday.

Elko was a 10th-round pick for the White Sox in 2022 and has progressed consistently through the team's system. He's maintained a .339/.423/.661 line across 130 plate appearances with Charlotte this season, earning him his first shot in the majors. Elko will man first base and hit eighth in his debut Saturday against Miami, per Vinnie Duber of AllCHGO.com.

Vaughn went 1-for-4 with a solo home run Friday against the Marlins.

Vaughn popped his fourth home run of the season in the second inning of Friday's win, his first long ball since April 20. He's still managed some moderate production in that span, hitting .243 with seven RBI and four runs scored across 18 games.

Walker went 2-for-4 with a double and a run scored Friday against the Reds.

Walker is slowly shaking off his slow start to the season, and he extended his hitting streak to five games with Friday's performance. He's gone 7-for-20 in that span while striking out only 14.3 percent of the time. Walker is still hitting just .213 for the season, though that number is progressively ticking up.

Horwitz (wrist) has gone 4-for-28 with five strikeouts on his rehab assignment split between Double-A Altoona and Triple-A Indianapolis.

Horwitz has been on assignment since April 27 and has needed extensive ramp-up time after missing all of spring training. He still hasn't found a rhythm at the plate, though he has struck out at a reasonable 16.7 percent clip. The Pirates need offensive help, but they may opt to let Horwitz start to hit better before activating him.

Rodriguez (finger) had his splint removed, is playing catch and has resumed a modified swing, MLB.com reports.

Rodriguez has been sidelined with a laceration on his right index finger since April 15. His progress has been slower than anticipated, though he should still have the chance to return later in May.

Busch went 2-for-4 with a double and a solo home run in Friday's 7-2 loss to the Mets.

Chicago's offense came on solo home runs by Kyle Tucker and Busch, with the latter recording his seventh long ball of the season and second in May. Busch has mostly struggled this month with a .192 batting average and 27.6 percent strikeout rate across eight games. Overall, he has a more respectable .258 average to go along with a strong .860 OPS.

Contreras went 2-for-4 with one run scored, a double and three RBI in Friday's 10-0 win over the Nationals.

Contreras got the Cardinals on the board with a two-run double in the first inning, and he brought in an additional run in the eighth when he drew a bases-loaded walk. He has recorded at least one RBI in six of the last nine games he's played in, and over that span he has gone 12-for-30 (.400) with six runs scored, three home runs and 13 RBI.

Goldschmidt went 2-for-4 with a solo home run, a walk and two total runs scored in Friday's 10-2 win over the Athletics.

Goldschmidt opened the scoring with a solo shot in the third inning. The first baseman has three homers over his last eight games, going 8-for-29 (.276) in that span. He's enjoying a resurgent campaign in his first year with the Yankees and is now up to four homers, 18 RBI, 23 runs scored and two stolen bases while maintaining a .345/.397/.486 slash line over 38 contests.
