Tigers signed RHP Carlos Monasterios to a minor league contract. Monasterios has appeared in just one game over the last two years due to elbow woes. He'll represent organizational depth.

Dodgers released RHP Carlos Monasterios. Monasterios posted a 4.38 ERA in 32 appearances for the Dodgers in 2010, but he had Tommy John surgery last year and needed surgery again last month to relocate the ulna nerve in his right elbow. It's not clear how long he'll be sidelined, but he'll need to find a new organization when he's healthy.

The Dodgers have revealed that Carlos Monasterios underwent Tommy John surgery on July 15. The right-hander will be sidelined until the second half of the 2012. Monasterios has pitched in just one game this season due to elbow trouble.
