Pittsburgh Pirates pitching prospect Bubba Chandler threw five scoreless innings on Tuesday, allowing four hits and three walks while striking out eight. It was a good bounce-back outing after allowing three earned runs on five hits and four walks in only 2 2/3 innings his last time out. The performance lowered the 22-year-old's ERA for the season to 1.91 with a 1.00 WHIP and 49 strikeouts over 33 innings pitched. He threw a season-high 86 pitches in the contest, continuing a progression toward a major league workload. The righty began the year as the Pirates' top prospect, and while that is still the case, the former third-round draft pick moved from No.12 overall up to the second-overall prospect in baseball in MLB.com's latest refresh of its Top 100 Prospects list. He remains a top stash candidate in redraft leagues and should make his way to the majors within the next month or so.

The Athletics placed left-hander T.J. McFarland (groin) on the 15-day injured list (retroactive to May 12) with a left-adductor strain and optioned right-hander Elvis Alvarado to Triple-A Las Vegas, the team announced. The club also reinstated right-hander Michael Otanez (shoulder) from the 15-day IL and recalled right-hander Jason Alexander from Las Vegas. McFarland was pulled from his latest outing after covering first base on a groundout on Sunday against the New York Yankees. The 35-year-old southpaw reliever will now be on the shelf for at least the next two weeks. The former fourth-rounder by the Cleveland Guardians in 2007 has not been anywhere near the fantasy radar and heads to the IL with an ugly 5.23 ERA (3.50 FIP) and 1.74 WHIP with four strikeouts and three walks in his 10 1/3 innings out of the bullpen.

Toronto Blue Jays shortstop prospect Arjun Nimmala, who started the year as MLB.com's 78th-ranked prospect overall, has moved up to the 59th-ranked prospect overall. That's a jump of 19 spots and the fourth-biggest move higher out of all the top 100 prospects. The 20th pick in the 2023 MLB Draft belted 16 home runs at Single-A last year in 82 games, although it came with a 31.3 percent strikeout rate. Fast forward to 2025, and the 19-year-old is hitting .280 with seven home runs at High-A through 29 games, and while the power is still there, the strikeout rate has fallen all the way to 20.5 percent, a marked improvement over 2024. The 6-foot-1 slugger has an ETA of 2028 according to MLB.com, so dynasty managers have some time to watch the youngster's development.

Cincinnati Reds outfielder TJ Friedl (wrist) left Tuesday's extra-inning loss to the visiting Chicago White Sox early due to right-wrist soreness, according to The Cincinnati Enquirer's Charlie Goldsmith. X-rays came back negative. Friedl was hit by a pitch in the game and also collided with shortstop Elly De La Cruz before being pulled from the game early. Before leaving in the fifth frame, the 29-year-old went 0-for-1 with a strikeout out of the leadoff spot before being replaced by Will Benson. Fantasy managers should treat him as day-to-day for now, but it wouldn't be a surprise if we don't see him for the rest of the series against Chicago, which concludes on Thursday. Friedl has been a regular outfielder for the Reds this year and entered Tuesday's game hitting a solid .276 (43-for-156) with three homers, 17 RBI, 23 runs and eight stolen bases in 39 games played.

Boston Red Sox infield prospect Marcelo Mayer went 2-for-4 with a walk, a three-run home run, and two runs scored for Triple-A Worcester on Tuesday. It's his first home run since April 27, a stretch of 11 games without one, but he's now up to eight on the season with a .275/.342/.500 slash line. His 38 RBI on the season make him the minor league leader in that category. The former fourth-overall draft pick still doesn't have a path to playing time with the big league club, but has logged starts at second base and third base in addition to his primary position of shortstop, giving the left-handed slugger some versatility that should help get him to the majors. Look for a call-up around midseason unless an injury opens up something sooner, and his potential power production makes him one of the top prospect stashes for fantasy managers who have the bench space or an NA spot to spare.
