Justin Wilson is replacing Francisco Rodriguez as the closer for the Detroit Tigers.

Brad Ausmus announced the move before the team's game against the Arizona Diamondbacks on Tuesday.

Rodriguez has 437 career saves, but has blown four in 11 tries this season. He also has a 8.49 ERA.

"I'm excited, fortunate for the opportunity," Wilson said, "but it comes at a time when one of my brothers down there is struggling.

"Frankie's done an unbelievable job with all of us down there and I just want to see him right, but for the time being, just give it what I got in the ninth and have some fun with it."
