The Boston Red Sox finally ran out of patience with starting pitcher Clay Buchholz. He is being sent to the bullpen, with Eduardo Rodriguez taking his spot in the rotation, Manager John Farrell told media in Toronto, where the Red Sox lost Friday night.

Buchholz, 31, has always been considered one of Boston’s most talented pitchers, but the results are not consistent. He began this season with a 2-5 record and 6.35 ERA. Buchholz made his 10th start Thursday at Fenway Park, allowing six earned runs over five innings in a loss to Colorado.

Rodriguez, 22, made a splash in his first major league season last year, going 10-5 with a 3.85 ERA. He began this season on the disabled list after suffering a dislocated kneecap in spring training. He had been making rehab appearances with Triple-A Pawtucket. Farrell said Rodriguez will start Tuesday’s game in Baltimore.

Buchholz has made two career relief appearances, one in his rookie season in 2007 and another in 2008.

Farrell said Buchholz will make multi-inning appearances in order to remain stretched out and could return to the rotation later in the season.
