Dempster, not Lester, to start Sunday vs. NY

BOSTON -- Red Sox manager John Farrell announced mildly disconcerting news about the Red Sox rotation Saturday, saying that left-hander Jon Lester will not start Sunday but has been pushed back until Tuesday night. Ryan Dempster will take Lester's turn Sunday night against the Yankees.

Farrell downplayed the significance of the move, saying that after Lester's return from the All-Star break, they decided he could benefit from a couple days more off.

Since Lester has been a part of the Sox rotation, he has always gotten extra rest at the All-Star break. Lester had eight days between starts at the break last season. In 2011, he was on the DL over the break with a shoulder strain and went 20 days between starts. In both 2009 and 2010, he had eight days, and in '08 the break was 12 days.

Lester last pitched a week ago Saturday in Oakland, so he would have been pitching with seven days' rest. Now he will get nine. Dempster will be working on eight days' rest. Farrell said rookie Brandon Workman, who took a no-hitter into the seventh inning against Oakland until Coco Crisp broke it up, will start Monday.

Lester is 8-6 with a 4.58 ERA in 20 starts. Since opening the season by winning his first six decisions, the left-hander is 2-6 with a 6.27 ERA in his last 11 starts.

Dempster pitched against the Yankees in the season-opening series in New York and took the loss in a 4-2 defeat. He went five innings, walking four and striking out eight, giving up a home run to Kevin Youkilis.
