After a strong start to his major-league career, opposing pitchers started to pepper Arizona Diamondbacks outfield prospect Ryan Waldschmidt with breaking pitches in the zone, and he struggled to handle the league's adjustment, according to Alex Weiner of Arizona Sports. With the D-backs getting healthier in the outfield recently, they opted to send the 23-year-old back to Triple-A Reno to work on some things after he hit .259/.314/.357 with a .671 OPS, no home runs, eight RBI, 11 runs scored, and five stolen bases in 112 at-bats. His 32.4% strikeout rate was 10 points higher than the major-league average, although his chase rate wasn't worse than average. Manager Torey Lovullo said that Waldschmidt needs to improve at controlling counts and not trying to do damage on pitcher's pitches. The team's top prospect, per MLB Pipeline, saw 38% breaking balls, which drew a 56% whiff rate. The former 31st overall pick in 2024 out of the University of Kentucky has lots of power/speed upside and has the skills to be a mainstay in Arizona for a long time, which makes him worth stashing still in dynasty/keeper formats. Lovullo is confident that he'll be back up with Arizona again this year.

Chicago White Sox catcher Kyle Teel (knee, hamstring) will begin a minor-league rehab assignment on Tuesday night with the Triple-A Charlotte Knights, according to Milb Central. Teel has yet to play in the big leagues this year after initially straining his hamstring while playing in the World Baseball Classic. Then the 24-year-old backstop sprained the LCL in his knee in late May while on a rehab assignment in the minors. Teel is finally restarting a rehab assignment, but he's nearing a return for his 2026 season debut in Chicago. Once fully healthy, he should see most of the starts for the Pale Hose behind the plate after slashing .273/.375/.411 with a .786 OPS, eight home runs, 35 RBI, 38 runs scored, and three stolen bases in 78 games and 297 plate appearances for the ChiSox in his first year in the big leagues. Teel was the 14th overall pick by the Boston Red Sox in 2023 out of the University of Virginia. He needs to improve against lefties, but at the very least, his on-base skills at the catcher position make him a top stash candidate if you're hurting at the position. Teel is currently rostered in just 8% of Yahoo leagues.

Washington Nationals left-hander DJ Herz (elbow) will start a minor-league rehab assignment on Tuesday with the Single-A Fredericksburg Nationals, according to Milb Central. Herz is close to making his return to the Nationals after having Tommy John surgery last year. Through his first two rehab starts in the rookie-level Florida Complex League, the 25-year-old southpaw has looked strong, throwing five scoreless innings with no walks and eight strikeouts. The Nationals aren't going to rush Herz back to the big leagues, though, so he could still require a handful of rehab starts before they consider reinstating him from the 60-day injured list. The former eighth-round pick by the Chicago Cubs in 2019 made his major-league debut with Washington in 2024 and went 4-9 with a 4.16 ERA (3.71 FIP) and 1.26 WHIP with 106 strikeouts and 36 walks in 88 2/3 frames across his 19 starts. Herz was more of a fly-ball pitcher, but his 29.3% whiff rate and 27.7% strikeout rate make him an interesting long-term starting option for those in deeper fantasy leagues. In those same formats, managers may want to consider stashing Herz now. He's available in all Yahoo leagues right now.

Los Angeles Dodgers left-hander Justin Wrobleski (hamstring) is listed as the team's probable starter for Tuesday's home game against the Tampa Bay Rays, according to Bill Plunkett of The Orange County Register. Wrobleski was pulled from his last start early last Thursday against the Pittsburgh Pirates with a right-hamstring contusion, but he was able to throw a normal between-starts bullpen, and he should be ready to go on Tuesday night at Dodger Stadium. The 25-year-old southpaw has emerged as a fantasy asset in 2026 with his move to a starting role in L.A. Going into Tuesday's game against the first-place Rays, Wrobleski has gone 7-2 with the Blue with a career-best 2.95 ERA(3.67 FIP) and 1.05 WHIP with 45 strikeouts and 16 walks in a career-high 73 1/3 innings pitched across his 12 appearances (11 starts). It's been a nice start to 2026, but fantasy managers may want to consider selling high on Wrobleski, who has a weak 15.3% strikeout rate (20.2% for his career). Coming off an injury while facing Tampa, we'd recommend fading Wrobleski as a fantasy streamer on Tuesday evening.
