Rogers, a 20-year veteran, has given up at least six runs in his last four starts

ARLINGTON, Texas -- Detroit Tigers veteran pitcher Kenny Rogers won't pitch again this season.

"We're not going to pitch Kenny. We shut him down for the rest of the season," Tigers manager Jim Leyland said Monday. Leyland didn't give a reason for his decision.

Rogers is a free agent at the end of the season and the Tigers are unlikely to re-sign the 43-year-old veteran of 20 major league seasons.

The left-hander allowed seven runs in 4 2/3 innings on Sunday against the Chicago White Sox and had given up at least six runs in four straight starts.

He finished the season with a 9-13 ERA and 5.70 ERA in 30 starts.

Rogers didn't speak with the media when he arrived at the ballpark about an hour before game time.

Rogers has a career record of 219-156 for the Tigers, Texas Rangers, Minnesota Twins, New York Mets, Oakland Athletics, and New York Yankees.
