The San Francisco Giants on Sunday placed rookie left-hander Carson Whisenhunt on the 15-day injured list, retroactive to Thursday, due to a strained back.
In a corresponding move, San Francisco recalled rookie right-hander Kai-Wei Teng from Triple-A Sacramento.
The Giants also expect Matt Chapman to be “fine” and not miss any games after fouling a ball off his left foot in Sunday’s 13-2 home win over the Baltimore Orioles, according to the San Francisco Chronicle. The third baseman left the game for a pinch runner after drawing a walk in the fifth inning and feeling soreness in his left foot.
Whisenhunt, 24, last pitched on Wednesday, earning the win in a 12-3 home victory over the Chicago Cubs. He allowed three runs on five hits and three walks with three strikeouts in five innings.
Manager Bob Melvin said on Sunday that Whisenhunt woke up with back tightness “a couple of days ago” and has not improved. The pitcher is fine throwing on flat ground, but his back flares up when he tries to throw off a mound, per the team’s website.
He is 2-1 since making his major league debut on July 28, with a 5.01 ERA, 12 walks and 16 strikeouts in 23 1/3 innings over five starts.
San Francisco selected Whisenhunt in the second round of the 2022 MLB Draft out of East Carolina.
Teng, 26, is 1-3 with an 8.78 ERA, nine walks and 12 strikeouts in 13 1/3 innings over four games (three starts) this season in San Francisco. Teng was 3-2 with two saves, a 3.63 ERA, 22 walks and 89 strikeouts in 57 innings over 26 games (four starts) with Sacramento of the Pacific Coast League.
