Manager Alex Cora said Friday that Gonzalez (back) could spend some time on the injured list, Chris Cotillo of MassLive.com reports.

No official move has been made just yet, but the Boston skipper hinted toward possible roster moves Saturday that could involve Gonzalez, who hasn't played since colliding with the Rangers' Josh Smith on Wednesday. Abraham Toro has been filling in at first base recently with Gonzalez injured and Triston Casas (knee) out for the season.

The White Sox plan to promote Elko to the major-league roster Saturday, Vinnie Duber of AllCHGO.com reports.

With Andrew Vaughn struggling to the tune of a .516 OPS with the big club, the Sox will now look to jumpstart their production at first base by giving Elko a look in the majors. The 26-year-old has been phenomenal at Triple-A Charlotte this season, slashing .339/.423/.661 with 10 homers and 23 RBI through 130 plate appearances. His first appearance will mark his MLB debut, and he could claim the starting job at first base immediately upon arriving in Chicago.

The Pirates placed Valdez on the 10-day injured list Friday, retroactive to May 8, due to left shoulder inflammation, Kevin Gorman of TribLive.com reports.

It's unclear when exactly the injury first surfaced for Valdez, but he's gone 2-for-13 across his past four contests. The Pirates are now down another option at first base, with Valdez joining Spencer Horwitz (wrist) and Endy Rodriguez (finger) on the shelf. Ji Hwan Bae was called up by Pittsburgh in a corresponding move, though it's likely to be Matt Gorski that sees a bump in playing time.

Mervis is not in the lineup for Friday's game against the White Sox.

It's right-hander Bryse Wilson on the bump for the White Sox, but the left-handed-hitting Mervis will nonetheless begin the festivities on the bench. It's the first time this season that Mervis -- who is 1-for-14 with 10 strikeouts in May -- is not in the lineup versus a righty. Liam Hicks is in the designated hitter spot for Miami.

Gonzalez (back) remains out of the lineup for Friday's contest in Kansas City.

He will get another day to rest his ailing back while Abraham Toro handles first base for the Red Sox. Gonzalez is expected to return to action sometime over the weekend.

Valdez is absent from the lineup for Friday's game against Atlanta.

Valdez had started each of the previous 18 games at first base against right-handed pitching, but he will begin this one on the bench as Atlanta sends righty Bryce Elder to the hill. Matt Gorski will play first base and bat sixth for the Pirates.

Elko is slashing .348/.431/.670 with 10 home runs and a 28.5 percent strikeout rate in 31 games for Triple-A Charlotte.

Elko is a righty-hitting first baseman who is already 26, so it's possible he's just a Quad-A hitter when it's all said and done. His 27.6 percent hard-hit rate and 67 percent contact rate aren't great marks, especially for an older first baseman. Elko is not yet on Chicago's 40-man roster.

Red Sox manager Alex Cora said Thursday that Gonzalez (back) is still sore but believes the infielder will be ready at some point this weekend, MLB.com reports.

Gonzalez was held out of Thursday's series finale against Rangers after sustaining a back injury Wednesday when he ran into Texas first baseman Josh Smith. Abraham Toro started at first base for the Red Sox on Thursday.

Guerrero went 3-for-4 with two runs scored and a walk in Thursday's win over the Angels.

Guerrero extended his hitting streak to 10 games and delivered his third multi-hit effort during the streak. The All-Star first baseman is batting sizzling .359 (14-for-39) with two homers, one double, six RBI and nine runs scored in those 10 contests. Although Guerrero has just four round trippers over 139 at-bats this season, his top-tier 54.2 percent hard-hit rate entering Thursday's action suggests some positive regression could be on the horizon in the power department.

Torkelson went 5-for-9 with two doubles, four RBI and two runs scored as the Tigers swept Thursday's doubleheader versus the Rockies.

Torkelson hadn't put together a multi-hit effort since April 17, but he took advantage of the Rockies' lackluster pitching in the twin bill. Over seven games in May, the first baseman has gone 9-for-30 (.300) with five extra-base hits and eight RBI. He's up to a .254/.356/.551 slash line with 10 homers, 11 doubles, 32 RBI, 28 runs scored and a stolen base over 38 games this season. Torkelson's performance took a step back in 2024, but he could have a breakout year in his fourth major-league season.
