Colorado Rockies right-handed pitching prospect Chase Dollander struck out six batters in his start against the Arizona Diamondbacks on Sunday afternoon. The young right-hander logged four 2/3 innings of one-run ball. He allowed three hits and two free passes. His lone blemish came in the opening frame on a solo shot by Arizona second baseman Ketel Marte. However, since allowing six runs to the Detroit Tigers on May 7, the former first-round pick has begun to turn the corner. In his last two starts, Dollander has tossed 10 2/3 innings with a 2.53 ERA and a strong 0.84 WHIP. Over this stretch, he has tallied 13 punchouts and allowed just five walks. Fantasy managers in deeper 15+ team formats should continue to stash Dollander on their bench. Even though he has progressed well, he should only be started in deeper NL-only formats in his next outing, against the New York Yankees at Coors Field.

San Francisco Giants left-handed pitching prospect Carson Whisenhunt enjoyed another strong outing on Sunday against Triple-A Salt Lake. In this outing, the left-hander logged seven innings of one-run ball (unearned run) and allowed just two hits. He served up one free pass and struck out five. In his last outing on May 13, Whisenhunt also logged seven innings. In that start, he struck out nine and served up three hits with no runs. Through his first 51 innings of the Triple-A regular season, the top pitching prospect in San Francisco has held a strong 3.00 ERA with a 1.00 WHIP. He has tallied 52 punchouts and allowed just seven free passes. Last summer, Whisenhunt logged 104 2/3 innings to the tune of a 5.42 ERA at Triple-A. Given his steady development, he should be in the mix to reach the majors in the coming months.

Seattle Mariners shortstop prospect Colt Emerson went 3-for-5 with a home run and a stolen base during their contest against High-A Vancouver on Sunday. Emerson has been swinging a hot bat over the last two weeks, and this outing extended his impressive stretch. Over his last 10 contests, the top-ranked prospect in the Seattle system has posted an impressive .349/.388/.535 slash line with one triple, two home runs, 16 RBI, a 4:4 K:BB, and two stolen bases. This is an excellent sign as the former 22nd overall pick from the 2023 MLB Draft held a modest .225/.331/.317 slash line across his first taste of High-A action during the 2024 campaign. Given his steady progression, fantasy managers should expect the No. 19-ranked prospect in the sport on MLB.com to push for his Double-A debut in the coming months.

New York Mets shortstop prospect Jett Williams went 3-for-5 with a double and an RBI during Sunday's contest against Double-A Hartford. This outing extended Williams' hitting streak to an impressive six games. During this stretch, the top prospect in the New York system has posted a strong .364/.462/.727 slash line with two doubles, two home runs, and one stolen base. Williams was only able to appear in 33 games in the minor leagues last season, but has been able to start the 2025 campaign well. Through his first 33 games of the Double-A regular season, the Rockwall-Heath HS product has held a .291/.385/.513 slash line with 10 doubles, four home runs, and eight stolen bases. Given the time he missed last season, Williams should contend for a Triple-A promotion in the second half of the season.

Texas Rangers starting pitcher Jack Leiter tossed seven innings of three-run ball against the Houston Astros on Sunday afternoon. Leiter carried a no-hitter into the seventh inning. However, Astros catcher Yainer Diaz hit a solo shot to end the bid. Then in the eighth, Leiter allowed two singles to Jake Meyers and Cam Smith before exiting the game. Relief pitcher Robert Garcia would then allow a three-run shot to Isaac Paredes, which raised Leiter's ERA. The former second overall pick has shown flashes of dominance this season but has also had several disappointing showings. He has allowed more than four runs twice and allowed three or more walks in three starts. Through 36 total innings, the right-hander carries a 4.25 ERA with a 1.11 WHIP. He will look to continue this strong run against the White Sox in his next outing.
