Left-hander Carson Whisenhunt’s volatile development reveals the grit required to anchor the San Francisco Giants’ future starting rotation.
Those who are fans of the San Francisco Giants still have plenty of reasons to root for Carson Whisenhunt.
The 25-year-old possesses the potential to develop into a frontline starter, but his journey to MLB has required persistence. Whisenhunt has spent four years carrying expectations as San Francisco’s potential left-handed ace of the future.
The Giants selected Whisenhunt in the second round with the 66th overall pick of the 2022 MLB Draft, and he quickly generated excitement after entering the organization.
His recent performances, however, have demonstrated both the potential that makes him intriguing and the development still required before he can secure a permanent rotation role.
Encouraging outing followed by difficult start
Whisenhunt delivered one of the best performances of his young career on August 11 against the American League West-leading Houston Astros.
The left-hander gave up one run on four hits with two strikeouts and three walks in 5.2 innings in a 4-1 home victory. At one point, he retired 11 consecutive hitters.
Whisenhunt had also dealt with minor arm injuries and discomfort this season. However, following the Houston performance, he indicated that he felt good physically and believed continued work would improve his feel for his pitches.
His next start provided a much different result.
Whisenhunt followed it up by allowing seven runs (six earned) on nine hits (one home run) with one strikeout and two walks in four innings of an 8-1 road loss against the Cleveland Guardians on Tuesday.
That performance provided another reminder that his development remains a work in progress.
Whisenhunt’s upside
There is still plenty to appreciate about what Whisenhunt brings to the mound.
He can effectively change speeds and possesses an impressive assortment of pitches. The southpaw features four solid offerings while bringing the experience and pitching savvy accumulated throughout his minor league career.
Durability remains another important part of his profile as San Francisco determines whether he can handle a permanent rotation role.
His ability to disrupt hitters’ timing could eventually become one of his greatest strengths. Whisenhunt does not need to depend entirely on overpowering opponents because changing speeds and presenting different looks can make at-bats uncomfortable.
The contrast between his Houston and Cleveland starts also creates an important challenge.
Whisenhunt showed against the Astros that he can settle into a rhythm, trust his arsenal and control an MLB lineup. Against the Guardians, he experienced how quickly an outing can unravel when execution disappears.
How he responds to those difficult starts will matter as much as his best performances.
Whisenhunt’s willingness to continue refining his arsenal should help as MLB hitters become increasingly familiar with him.
He will enter Spring Training next year as one of the leading candidates for a place in San Francisco’s rotation.
The remainder of 2026 gives Whisenhunt an opportunity to prove that he can turn promising individual performances into the consistency required of a long-term Giants starter.
