KANSAS CITY, MO. – After Friday's game in which starter Matt Shoemaker couldn't even last one inning before exiting with nine runs scored off him, the Twins brought some new energy into their pitching staff.
Righthander Griffin Jax joined the team Saturday from Class AAA St. Paul. The 26-year-old had been strong for the Saints, going 3-1 with a 3.33 ERA and no home runs allowed.
Manager Rocco Baldelli said Jax would start in the bullpen.
"He's a strike-thrower, too. He's a guy that if we need to bring in to any kind of situation, really, he can go out there and compete," Baldelli said. "And he has plenty of pitches to work with. … He adapts very well and will figure out whatever it is we're asking him to do."
When he debuts, Jax will become the first drafted Air Force Academy graduate to play in the majors.
"The path I took to this point has really been unique, and it sort of helped formulate and mold me into a different type of person," Jax said. "… They helped push me into a platform to really help pursue my baseball career as well as represent the Air Force as a whole. Couldn't be more thankful for them for supporting me to get to this point."
In the corresponding move, the Twins designated reliever Juan Minaya for assignment after he made four appearances and posted a 4.26 ERA.
Michael Pineda will not start as scheduled Sunday. He is dealing with forearm discomfort, and delaying his start will give him another day of recovery. He and fellow injured starter Kenta Maeda — who also has general arm soreness — will throw a bullpen session Sunday.
