The Arizona Diamondbacks officially placed right-hander Corbin Burnes (elbow) on the 15-day injured list on Tuesday with right-elbow inflammation and recalled left-hander Tommy Henry from Triple-A Reno in a corresponding move, according to Arizona Sports' John Gambadoro. With Burnes potentially missing significant time, potentially for the rest of the season, right-hander Ryne Nelson will jump into the starting rotation and will have an opportunity to stick around for a while if he pitches well enough. Burnes will have a second opinion on his right arm later this week, at which point fantasy managers should have a better idea if he'll miss the rest of 2025. Losing Burnes, the team's ace, for the rest of the year would be a tough blow for the Snakes. He's gone 3-2 with a 2.66 ERA and 1.17 WHIP with 63 K's in 64 1/3 innings over 11 starts in his first year in the desert.

Arizona Diamondbacks infield prospect Jordan Lawlar is settling back in at Triple-A Reno after being optioned on May 29. The former sixth-overall draft pick went 0-for-4 with three strikeouts in his first game back with the Aces, but went 3-for-4 with a walk, two RBI, and a run scored in the second game on Sunday. The 22-year-old didn't do much in his time with the big league club, but wasn't given a chance to play every day (or even everyother dayin some cases), so surely it was challenging to get in a rhythm. At some point, there will be another opportunity to join the D-backs in a full-time role later this season, and the right-handed hitter is still the fourth-ranked prospect in all of baseball; fantasy managers will just have to wait a bit longer to see it. Continue to stash Lawlar in leagues where you have an open bench or NA spot.

Texas Rangers infield prospect Sebastian Walcott continues to show well at Double-A, going 6-for-16 (.375) with a double, two home runs, five RBI, six runs scored, three stolen bases, and a 3:2 BB:K over his last four games for the Frisco RoughRiders. The Rangers' top-ranked prospect's season-long slash line sits at .249/.341/.449 with eight home runs and 11 steals, and with the uptick in performance, he's pacing for a promotion to Triple-A in the coming months. The 19-year-old has the makings of a five-category fantasy producer and could be in the big leagues in the second half of 2026, so fantasy managers should have a keen interest in the 6-foot-4 slugger's progression.

The Colorado Rockies announced on Tuesday that they placed rookie right-handed reliever Zach Agnos on the bereavement list and recalled right-hander Angel Chivilli from Triple-A Albuquerque in a corresponding move. Agnos will be away from the team for at least a couple days and probably won't rejoin the club until Friday for their series opener at Coors Field against the New York Mets. The 24-year-old has quickly earned the trust of the coaching staff in high-leverage situations in his first year in the big leagues. Agnos picked up his fourth save of the season in the win on Monday over the Miami Marlins and has become one of Colorado's best bets for saves chances in the unlikely event that they pop up (the Rockies have just 10 wins all season). With Agnos away for a few days, Seth Halvorsen or Jake Bird could be called upon if the Rockies have another save situation between now and Friday.

Arizona Diamondbacks right-hander Corbin Burnes (elbow) is going for a second opinion on his injured right elbow on Thursday or Friday after initial tests were inconclusive, according to Arizona Sports' John Gambadoro. Burnes left his last start on Sunday against the Washington Nationals in the fifth inning in a good amount of pain, leading many to believe he had just suffered a season-ending elbow injury. That could still be the case, but we'll know more by this weekend. Either way, the 30-year-old veteran will almost certainly land on the 15-day injured list and could miss extensive time if he avoids a season-ending injury. Fantasy managers in redraft leagues shouldn't outright drop the D-backs ace until we know more about the severity of his elbow injury. Arizona already has Eduardo Rodriguez (shoulder) on the IL, but he's expected to rejoin the rotation next week.
