Houston Astros first baseman Christian Walker (back) is starting at first base and batting cleanup for Houston in Friday's contest against the visiting Tampa Bay Rays and right-hander Nick Martinez at Daikin Park, according to MLB.com. Walker will return to the starting nine following an off day on Thursday after he was removed from Wednesday's series finale early against the Minnesota Twins with stiffness in his lower back. Fantasy managers are hoping that the 35-year-old veteran right-handed slugger can get his bat going again with the All-Star break approaching quickly. After a hot start in 2026, Walker went 23-for-103 (.223) with three homers, six doubles, a triple, 13 RBI, nine runs scored, nine walks, and 31 strikeouts in 26 games in June to drop his season slash line down to .239/.310/.469 with a .780 OPS in 361 plate appearances. He has a good matchup to get back on track, as he's hitting .500 with a 1.371 OPS, one homer, and four RBI in 12 career at-bats against Martinez.

The Cleveland Guardians recalled right-handed pitching prospect Franco Aleman from Triple-A Columbus on Friday, a source told Francys Romero. Aleman has been outstanding for Columbus this year, posting a 0.32 ERA with 43 strikeouts over 28 1/3 innings pitched. The 26-year-old Cuban hurler made his big-league debut with Cleveland earlier this year and allowed a solo home run with a walk and a strikeout in 2 2/3 relief innings. The former 10th-round pick in 2021 out of the University of Florida has been as dominant as they come out of the bullpen in the minors this year, although he will most likely be utilized in more of a middle-relief role in his return to the majors, limiting his overall fantasy upside. Aleman is not listed among the Guardians' top-30 prospects, per MLB Pipeline, and he's had a 4.36 ERA, 1.28 WHIP, and 293:77 K:BB in 198 1/3 innings over 151 outings (eight starts) over his five minor-league seasons.

Minnesota Twins catcher Ryan Jeffers (hand) is starting a minor-league rehab assignment with Triple-A St. Paul on Friday, according to Aaron Gleeman of The Athletic. Jeffers will serve as the Saints' designated hitter on Friday, roughly six weeks after having surgery for a fractured hamate bone in his left hand. It's unclear how long Jeffers will be on his rehab assignment, but barring a setback, he should have a shot to rejoin the Twins as their primary catcher before the All-Star break from July 13-16. Fantasy managers seeking an upgrade at catcher will want to consider stashing Jeffers now, too, after he was slashing .295/.408/.541 with seven home runs, 26 RBI, 26 runs scored and a stolen base in 148 plate appearances across 37 games before fracturing his hand. Veteran Victor Caratini has been seeing most of the starts behind the dish for the Twins with Jeffers out, with Alex Jackson serving as the No. 2. Jeffers is currently rostered in only 28% of Yahoo leagues.

St. Louis Cardinals outfielder Lars Nootbaar (rest) is out of the starting lineup ahead of Friday's game against the Chicago Cubs. This appears to be a regular rest day for Nootbaar, with the Cubs sending southpaw David Peterson to the mound. Nootbaar has started in 11 straight games, so he could use a rest day. In his place, Jose Fermin will cover left field and bat seventh on Friday. Due to injuries, Nootbaar has only played in 23 games this season. He's slashing .300/.387/.463 with two home runs and eight RBI in 93 plate appearances. He could be an under-the-radar deep league addition at the moment.
