Twins lefthander Francisco Liriano was placed on the 15-day disabled list because of a posterior shoulder strain. Liriano lasted just two innings on Thursday before coming out of the game.
"The last three or four days it has not been normal soreness,'' Liriano said. "It wasn't getting any better [Thursday].''
Liriano, 9-9 with a 4.84 ERA, will undergo a MRI exam on Friday to make sure nothing is seriously wrong.
The Twins called up lefthander Scott Diamond from Class AAA Rochester to replace Liriano in the rotation. Diamond is 4-14 with a 5.56 ERA in 23 games for the Red Wings. He has lost his past eight decisions while posting a 6.24 ERA over 10 starts. He made his major league debut on July 18 against Cleveland, giving up three earned runs over 6 1/3 innings.
Diamond was scratched from his scheduled start on Thursday, so he will be well-rested for Friday's game.
Kubel next to go?
The Twins might not be done dealing. Outfielder Jason Kubel reportedly has been claimed by a club, and there's a noon Friday deadline for the Twins to reach a deal for him or they can pull him back from waivers.
Kubel said Thursday that things have been tough for him lately. He had to leave the team Monday to take care of a family matter and has been frustrated about the mounting losses.
"It's tough to come here and prepare for games and then start talking to everybody about what no one is supposed to know,'' Kubel said. ''There's a lot of things going through my head. I can't pinpoint on one thing.''
