SAN FRANCISCO — The already lean San Francisco Giants pitching rotation appeared to lose a second member in as many nights on Tuesday.

Starting pitcher Adrian Houser left Tuesday’s game against the Reds after only 1.1 innings and 26 pitches. After his final pitch to Hector Rodriguez, a 93.9 mile per hour fastball, Houser grimaced and shook his arm. Houser has made 25 appearances and 15 starts in his first season as a Giant. The 10-year veteran is 4-7 with a 4.08 ERA, and has thrown 108 innings.
Manager Tony Vitello and a member of the Giants’ medical staff went out to the mound, and after a brief discussion in the middle of the diamond pulled Houser from the game.
Right-hander Anthony Molina then came out of the bullpen to make his Giants debut. Molina, who has made 55 major league appearances with the Rockies and Braves, was part of the trade that sent former starter Tyler Mahle to Atlanta.
Houser’s injury came around 24 hours after Carson Whisenhunt sustained a similar-looking injury against Cincinnati on Monday. The Giants announced on Tuesday afternoon that Whisenhunt would require Tommy John surgery to repair his torn UCL. Whisenhunt will be the third Giants starter to undergo the operation. Hayden Birdsong and Trevor McDonald also had their seasons cut short by the surgery.

San Francisco called up Spencer Bivens to fill Whisenhunt’s place on the roster. Tristan Beck and and Matt “Tugboat” Wilkinson are both candidates to be promoted if Houser’s injury is diagnosed as serious.
The Giants experienced another injury scare in the top of the fourth inning. Center fielder Drew Gilbert, one of the few regulars still left in the lineup, slammed full speed into the outfield wall after tracking down a fly ball off the bat of Sal Stewart.
Gilbert remained down for several moments. After being attended to by medical personnel, he was able to get to his feet and remained in the game.
