Right-handed reliever JT Brubaker will start Friday's bullpen game for the Giants, according to Alex Pavlovic of NBC Sports Bay Area .
San Francisco has rarely used a bullpen game this season. But the Giants are now thin in the rotation after a season-ending injury to Trevor McDonald . The team also traded Robbie Ray to the San Diego Padres and Tyler Mahle to the Atlanta Braves before Monday's deadline.
The Giants called up four pitchers from Triple-A Sacramento after Monday's trade deadline moves. But only right-handed pitcher Blade Tidwell got an opportunity to start thus far. Tidwell pitched well in Tuesday's 5-4 loss. He threw 5 innings, giving up 2 runs and striking out 3 Rangers batters.
San Francisco's starting rotation now consists of Logan Webb , Landen Roupp , Carson Whisenhunt and Blade Tidwell. Veteran pitcher Adrian Houser was part of the Opening Day rotation, but was moved to the bullpen after his struggles.
San Francisco Giants fans reacted to the announcement that JT Brubaker is Friday's starter:
@NightOwlotw: "Bullpen game? It's gonna be Brubaker for 3 innings. Houser for 5 innings if we already losing Houser will be 6. If we somehow are winning then Winn or Smith will be 9th inning."
@Glockerz5: "What are we doing – give all the young guys a shot bring em up!"
@LurieWarRoom: "JT Brubaker is not responsible for being tonight's starting pitcher. Responsibility lies with the people who created a world in which JT Brubaker is tonight's starting pitcher. I hope the distinction is clear. #ThePoseyFiles #BusterGate."
@BobJogs: "Great!!! Sweep by the Tigers!!! Curious to see how many empty seats there will be."
