New York Yankees shortstop prospect George Lombard Jr. was the biggest riser in MLB.com's latest refresh of its top prospects list, jumping 49 spots from No. 93 to No. 44 after a fantastic start to the High-A season. The 2023 first-round draft pick hit .329, but perhaps more impressive was his outstanding eye that produced a 20.7 percent walk rate and .495 on-base percentage. Chipping in 11 steals was the icing on the cake. This was all done in 24 games as a 19-year-old, so there should be plenty more growth to come. The 6-foot-2 slugger isn't expected to get to the majors until 2027, but a fast riser like Lombard Jr. is just the type of player dynasty managers should be keeping an eye on as they could get there -- and produce -- sooner than expected.

Chicago White Sox catching prospect Kyle Teel went 1-for-2 with two walks, an RBI, and two runs scored on Sunday for Triple-A Charlotte, extending his current hit streak to 12 games and hitting safely in 19 of his last 20. During the 12-game stretch, the left-handed hitter is 15-for-44 (.341), raising his season-long slash line to .264/.361/.416 with a .358 wOBA and 107 wRC+. The former first-round draft pick is expected to make a big league debut this year, and it could come within the next month if he keeps hitting. Chicago's second-ranked prospect would in all likelihood join fellow prospect (Chicago's No. 5) Edgar Quero at the big league level, but with Quero holding his own in the majors, it's unclearwhat type of playing time split there would be, which could limit Teel's usefulness for fantasy.

Tampa Bay Rays outfielder Josh Lowe (oblique) went 2-for-3 with two singles, a run scored and a walk in a minor-league rehab appearance with Triple-A Durham on Sunday while serving as the Bulls' designated hitter. Lowe moved his rehab assignment from the rookie-level Florida Complex League to Triple-A last Thursday after hitting a two-run homer with two walks in five plate appearances in the FCL. In three games with the Bulls, the 27-year-old left-handed hitter has gone 2-for-9 with three walks and four strikeouts. Lowe suffered a right-oblique strain on Opening Day but could be ready to make his return from the injured list by the weekend or early next week if he can avoid a setback. His intriguing mix of power and speed -- he hit 20 bombs and stole 32 bases in 2023 -- makes him stash-worthy in all fantasy leagues, and he should be an everyday player in Tampa when he returns.

Cleveland Guardians outfield prospect Jaison Chourio injured his right shoulder during an at-bat back on May 3, and although he finished the AB, he was removed from the game afterward. The switch-hitter has not appeared in a game for High-A Lake County since then, however, no update on his status has been provided. The 19-year-old had a great season at Single-A last year, slashing .269/.414/.398 with five home runs, 44 steals, a .395 wOBA, and a 144 wRC+, but High-A was proving a bit more challenging this year. The 6-foot-1 slugger was hitting just .214 through 21 games, but was still getting on base thanks to his ability to draw walks, registering an impressive 17:21 K:BB in 91 PA. Chourio isn't expected to make it to the majors for a couple of years, but with solid contact ability, a keen eye, and a penchant for stealing bases, this injury is something to monitor in the event it jeopardizes his timeline at all.

Seattle Mariners right-hander Logan Gilbert (elbow) said that he will throw his first bullpen session on Tuesday. Gilbert threw off the mound to a standing catcher on Sunday. It's still to be determined on when he will possibly start a minor-league rehab assignment, but the 28-year-old reiterated that everything has felt good with his right elbow at every step so far. Gilbert was placed on the 15-day injured list in late April with a right-elbow injury, but as long as he doesn't suffer a setback as he begins ramping up, there's a chance he could be back for fantasy managers and in Seattle's starting rotation by the end of May. The former 14th overall pick in 2018 out of Stetson University is a must-start in fantasy each and every time he takes the mound when he's healthy. He had a 2.37 ERA and 0.79 WHIP with 44 punchouts in 30 1/3 innings in his six starts before getting hurt.
