TORONTO (AP) Struggling Red Sox pitcher Clay Buchholz is being moved to the bullpen and left-hander Eduardo Rodriguez will take Buchholz's spot in the rotation, starting Tuesday at Baltimore.
Buchholz is 2-5 with a 6.35 ERA in 10 starts and has allowed five earned runs or more six times. He gave up season-highs of six runs and three home runs in Thursday's 8-2 loss to Colorado.
Rodriguez (right knee) is on the 15-day DL has not pitched for the Red Sox this season. He's 0-3 with a 3.54 ERA in five rehab starts at Triple-A Pawtucket. He went 10-6 with a 3.85 ERA as a rookie in 2015.
Buchholz has made two career relief appearances, one in his rookie season in 2007 and another in 2008.
Manager John Farrell said Buchholz will make multi-inning appearances in order to remain stretched out and could return to the rotation later in the season.
