The Red Sox have placed first baseman Kevin Youkilis (thumb) on the 15-day disabled list, according to The Boston Globe.
Youkilis, who is hitting .307 with 19 homers and 62 RBIs, is the fifth position player from Boston’s opening day lineup to land on the DL this season.
With Youkilis out, the Red Sox activated infielder Mike Lowell from the disabled list to start at first base. Lowell is hitting .213 with two homers and 12 RBIs in 31 games this season.
Lowell hasn’t played since June 22 because of a sore hip and was rumored to be a candidate to be designated for assignment earlier this week.
