Clay Buchholz to Disabled List; Andrew Miller Will Start on Monday

The Red Sox have placed right-hander Clay Buchholz on the 15-day disabled list with a lower back strain and selected left-hander Andrew Miller to the active roster. The team announced the moves prior to Sunday's game against Milwaukee.

Miller will immediately take over Buchholz's spot in the rotation and pitch Monday night at Fenway Park against San Diego.

Buchholz has been bothered by his back for a few weeks. He was given two extra days off before a start earlier in the month and then left his last outing in Tampa Bay after just 81 pitches in five dominant innings. At the time, he said the early exit came in part to avoid a trip to the DL.

The right-hander had allowed just one run on two hits when he left the game. He is 6-3 with a 3.48 ERA in 14 starts overall, and 5-0 with a 2.59 mark in his last nine appearances.

Miller, 26, was 3-3 with a 2.47 ERA in 13 appearances (12 starts) for Triple-A Pawtucket. He went 2-1 with a 1.78 ERA over his last four outings for the PawSox.

The 26-year-old left-hander signed as a minor league free agent in December. He was the sixth overall selection by the Detroit Tigers in the 2006 draft.
