San Francisco Giants outfielder Jung Hoo Lee (shoulder) will have season-ending surgery on his dislocated left shoulder next Tuesday in Los Angeles, with Dr. Neal ElAttrache doing the procedure. Lee is expected to make a full recovery by the start of next spring. Manager Bob Melvin said Lee will remain around the team and rehab in San Francisco. The 25-year-old Japanese outfielder hit .262/.310/.331 with two home runs, four doubles, eight RBI, two stolen bases, 15 runs scored, 10 walks and 13 strikeouts in 158 plate appearances in his first 37 major-league games for the Giants before suffering a season-ending shoulder injury on May 12 against the Cincinnati Reds. Lee tore the labrum in his shoulder but should be ready to roll for the start of the 2025 season as San Fran's starting center fielder and leadoff hitter. If you haven't already done so in redraft leagues, Lee can be safely dropped now.

New York Yankees outfield prospect Jasson Dominguez (elbow) will continue his rehab assignment at Triple-A Scranton/Wilkes-Barre after playing the last 10 games at Double-A Somerset. During his 10-game run at Double-A, the 21-year-old hit .316 (12-for-38) with four home runs, eight RBI, eight runs scored, and a stolen base. He also had a successful four-game stretch at Single-A where he went 5-for-13 (.385). Unfortunately for fantasy managers that have been stashing the switch-hitter, Dominguez will likely stay at Triple-A once he is eligible to come off the injured list, as the Yankees outfield is crowded right now and they do not currently need him with New York owning the best winning percentage in baseball. Regardless, he should continue to be stashed in all formats, as he'll be a multi-category producer whenever he does get the call.

Seattle Mariners executive vice president and general manager of baseball operations Justin Hollander announced on Monday that the team optioned rookie outfielder Jonatan Clase to Triple-A Tacoma. The 22-year-old appeared in his first 15 big-league games and went 6-for-34 (.176) with no homers, a double, three RBI and 13 strikeouts in 35 plate appearances. In 28 games for Tacoma in 2024, Clase has hit .255 (28-for-110) with four home runs, 16 RBI and 12 stolen bases. The Mariners' No. 10 prospect, per MLB Pipeline, only started three games while with the big-league roster and could use more everyday playing time back on the farm. The Dominican switch-hitting outfielder relies mostly on speed, but there's also some intriguing power despite his 5-foot-9 frame. Clase is only worth stashing in dynasty/keeper leagues in 2024.

Seattle Mariners outfield prospect Lazaro Montes went 1-for-3 with two walks on Sunday for Single-A Modesto. The 19-year-old scored once and collected his league-leading 57th RBI in the contest as well. The hit also extended his current hitting streak to eight games, during which he's batting .394 (13-for-33). On the season, the left-handed hitter is slashing .330/.429/.534 with nine home runs, a .450 wOBA, and a 158 wRC+. With nearly as many walks (33) as strikeouts (40), he's shown great patience at the plate as well. The Mariners' fourth-ranked prospect seems to be on the precipice of a promotion as he proved he could hit High-A pitching in 2023 as well, but is still a couple years away from the majors. Montes should already be on the radar for dynasty managers, and will begin to creep up the MLB Top 100 Prospects list, currently ranked at 82 overall.

Arizona Diamondbacks catching prospect Adrian Del Castillo is having a fantastic season at Triple-A this season, slashing .340/.391/.612 with 10 home runs, 37 RBI, and 43 runs scored in 206 at-bats (51 games). The 24-year-old is also leading all minor leaguers in doubles with 22. While Tucker Barnhart surely provides an invaluable veteran presence at the catcher position on the big league club, his .154 batting average, no home runs, and .494 OPS probably won't cut it much longer as long as Del Castillo continues to hit. The left-handed hitter may not have a big impact for fantasy initially as he'd be the backup to primary catcher Gabriel Moreno, but we should see him in the majors at some point this season. If Moreno were to suffer an injury, Del Castillo could quickly become fantasy-relevant.
