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.

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.

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.

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.

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.
