Carson Whisenhunt - Fantasy Baseball Prospects Waiver Wire Stashes (Week 9)

Fantasy Baseball Prospects, Waiver Wire Stashes, MLB Rookies Call-Ups Sleepers

Carson Whisenhunt is a fantasy baseball waiver wire stash for Week 9 (2025). Target Carson Whisenhunt as a top prospect free-agent waiver wire pickup for fantasy baseball.

BALLER MOVE: Add in 14+ team Leagues

CALL-UP ETA: June

ANALYSIS: San Francisco Giants left-handed pitching prospect Carson Whisenhunt is considered the No. 2-ranked prospect in the system on MLB.com.

After spending most of his 2024 campaign with Triple-A and holding a modest 5.42 ERA with a 1.61 WHIP, Whisenhunt has shown significant progression this season.

Since allowing seven runs on April 25 to El Paso, Whisenhunt has been one of the top pitchers in the Pacific Coast League. Over his last 28 innings of work, Whisenhunt has held a stellar 1.29 ERA with a 0.71 WHIP. During this stint, the left-hander has tallied 28 batters and allowed just two walks.

Over his first 23 innings of work this season with the Sacramento River Cats, Whisenhunt posted a high 5.03 ERA with a 1.35 WHIP.

While the Giants opted to add Hayden Birdsong to the rotation, Whisenhunt may be called on quite soon as well. Earlier this week, the Giants placed right-hander Justin Verlander (pectoral) on the 15-day IL. If his stint on the IL lasts longer than expected, Whisenhunt would provide some much-needed depth to the rotation.
