The San Francisco Giants placed right-hander Jordan Hicks on the 15-day injured list with right shoulder inflammation ahead of Tuesday's game against the hosting Milwaukee Brewers. Hicks has been battling a lingering shoulder issue and was unavailable for Friday's contest against the Seattle Mariners after feeling a "zinger" down his right arm on two of his final three warmup pitches, but he was cleared to pitch after playing catch without issue the following day before eventually going on the IL. Hicks is 4-7 with a 3.90 ERA this year, making 20 starts before being moved to the bullpen in late July. The 27-year-old righty has made eight appearances in relief and logged 108 1/3 innings overall for the Giants this season. Ryan Walker and Camilo Doval figure to share save chances in San Francisco until Hicks is back in the mix, which likely won't be until mid-September.

Arizona Diamondbacks second baseman Ketel Marte (ankle) resumed hitting in the cages before Tuesday's series opener against the visiting New York Mets at Chase Field. Marte, who was forced to leave the Aug. 18 game after aggravating what the club has said is a "low-grade" ankle sprain stemming from Aug. 12, was actively doing agility exercises in a pool before resuming swinging on Tuesday. There is still no official date of a return on the table or if a minor-league rehab assignment will be necessary, but Marte has been asymptomatic, and fantasy managers can expect him to return at some point in early September for the time being. Until the 30-year-old All-Star switch-hitter gets back into Arizona's lineup, Geraldo Perdomo should experience an uptick in fantasy value as the team's primary leadoff hitter.

Arizona Diamondbacks first baseman Christian Walker (oblique) took live batting practice before Tuesday's series opener against the visiting New York Mets at Chase Field. Manager Torey Lovullo said Walker could play in simulated games at Salt River Fields in a controlled environment as early as this weekend. The 33-year-old Gold Glover injured his left oblique on July 29 against the Washington Nationals, with an MRI exam taken the next day showing a low-grade strain. Walker should be back to help Arizona and fantasy postseason rosters at some point in early September, but until then, Josh Bell should continue to serve as the club's everyday first baseman.

Milwaukee Brewers outfielder Christian Yelich (back) said he underwent a microdiscectomy and said he'll have a rough timeline of three months. By the time Yelich and the Brewers had decided in the surgical route, the pain was impacting his day-to-day life, not just baseball activity. He thinks the surgery will help alleviate the chronic back issues he's dealt with for years. "I think everybody sees back surgery, and they kind of are like, 'Oh, that's the end of your career.' Honestly, in my mind, that couldn't be any farther from the truth. I think that it's going to help me tremendously. I think I'll probably feel a lot better than I have in the last few years going forward, so in that sense, it's cool," Yelich said. The 32-year-old should be ready for the start of spring training, but fantasy managers are going to be hesitant to pull the trigger on an aging outfielder coming off a serious back surgery.

Texas Rangers manager Bruce Bochy confirmed on Tuesday that the plan is for right-handed pitching prospect Jack Leiter to start on Wednesday evening against the Chicago White Sox at Guaranteed Rate Field. Leiter was on the team's taxi squad on Tuesday and will officially be recalled from Triple-A Round Rock on Wednesday. The team's No. 4 prospect, per MLB Pipeline, gets the best matchup in baseball, but he's still going to be a bit of a dicey streaming option for fantasy managers after pitching to an eye-popping 16.39 ERA and 2.57 WHIP with seven strikeouts, six walks and three homers allowed in 9 1/3 innings over his first three big-league starts earlier in 2024. Leiter has been much better in 77 innings for Round Rock (3.51 ERA, 1.26 WHIP, 110:35 K:BB), but better command will be required if he's to wants to pitch well on Wednesday and perhaps stick around in the rotation in Texas once rosters expand.
