Carson Whisenhunt - MLB News, Rumors, & Updates

Could make 2026 debut Monday Susan Slusser of the San Francisco Chronicle relays that Whisenhunt could be called up from Triple-A Sacramento and start in the Giants' series opener against the Padres on Monday.

Impact Whisenhunt was unable to crack the Giants' Opening Day roster after struggling with his command and control during spring training. He hasn't exactly been much better in Triple-A, posting a 4.85 ERA and 1.46 WHIP over 26 innings. However, he pitched well in his last start against Salt Lake on Tuesday, when he allowed one run on three hits while striking out eight across six innings without issuing a walk. Whisenhunt appeared in five major-league games for the Giants in 2025 and finished the season 2-1 with a 5.01 ERA, 1.46 WHIP and 16:12 K:BB across 23.1 frames.

Bound for Triple-A The Giants optioned Whisenhunt to Triple-A Sacramento on Wednesday, Justice delos Santos of The San Jose Mercury News reports.

Impact Though Whisenhunt had shown improved velocity during spring training, he struggled with his command and control. Over four appearances (two starts) during Cactus League play, Whisenhunt was charged with 10 earned runs on eight hits and eight walks while striking out 14 batters over 9.1 innings. With Whisenhunt sent down and with Hayden Birdsong (forearm) set to begin the season on the injured list, Trevor McDonald and Carson Seymour would appear to be first in line to join the San Francisco rotation if a spot were to open up.

Struggles in spring game Whisenhunt logged a blown save in Monday's 6-5 Cactus League win over the White Sox, allowing four earned runs on five hits and a walk while striking out two across 1.2 innings.

Impact Whisenhunt entered in the third inning and surrendered two singles and a double that led to two runs. He then allowed a walk and two doubles before being pulled in the fourth, as the White Sox took a 4-3 lead. On a more positive note, the southpaw averaged 95.6 mph on his four-seamer, a significant uptick from his average of 92.6 mph in 2025. The 25-year-old could compete for a spot in the bullpen ahead of Opening Day, but it wouldn't be surprising if he begins the season in Triple-A Sacramento's rotation. He recorded a 5.01 ERA, 1.46 WHIP and 16:12 K:BB while giving up six long balls across 23.1 innings in five starts for San Francisco last season.

Velocity up in Giants camp Whisenhunt was sitting 96-97 mph during a simulated game Thursday, Justice delos Santos of The San Jose Mercury News reports.

Impact Delos Santos notes that the readings were courtesy of Trackman, so it's a legitimate velocity increase for Whisenhunt, who averaged 92.6 mph with his four-seamer last season. It will be interesting to watch whether the southpaw is able to carry the velocity spike into Cactus League play and the regular season, as it could help spur a breakout. Whisenhunt entered spring training likely on the outside looking in for a spot in the Giants' rotation after holding a 5.01 ERA and 16:12 K:BB over 23.1 innings covering five starts in 2025.

Fans two in rehab game Whisenhunt allowed one earned run on two hits and two walks while striking out two across three innings in Triple-A Sacramento's 4-2 loss to Round Rock on Sunday.

Impact Whisenhunt was placed on the 15-day injured list Aug. 31 due to a back strain but appears to be nearing a return to the big leagues. He made his first rehab appearance against Round Rock last Tuesday, giving up three runs (two earned) over 1.2 innings while tossing 25 of his 39 pitches for strikes. The left-hander stretched out slightly Sunday, throwing 46 pitches (30 strikes). If the 24-year-old returns to the majors ahead of the regular-season finale Sunday, he'll likely replace Trevor McDonald or Kai-Wei Teng in the rotation.

Slated for rehab outing Tuesday Whisenhunt (back) is expected to throw a couple innings in a rehab appearance Tuesday with Triple-A Sacramento, Justice delos Santos of The San Jose Mercury News reports.

Impact Whisenhunt was placed on the 15-day injured list Aug. 31 due to a back strain but won't require a lengthy stay on the shelf. After completing a bullpen session Sunday that incorporated all of his pitches, Whisenhunt will make an abbreviated rehab appearance Tuesday before potentially rejoining the Giants next weekend. San Francisco has been getting by of late with Kai-Wei Teng and Carson Seymour as its back-end starters, but Whisenhunt could replace either pitcher in the rotation once he's activated.

Throwing bullpen session Monday Whisenhunt (back) will throw a bullpen session Monday, Shayna Rubin of the San Francisco Chronicle reports.

Impact It appears to be the first time Whisenhunt has thrown from the bump since he landed on the 15-day injured list at the end of August with a back strain. Whisenhunt is eligible for activation this weekend, and it's possible he'll return then if the Giants don't think he needs a rehab start.
