Second baseman Jed Lowrie was placed on the 15-day disabled list Wednesday with a shin contusion, and the A's continued their pitching shuffle.
Lefty Eric Surkamp was officially recalled from Triple-A Nashville to make tonight's start at Boston, a plan that manager Bob Melvin announced after Tuesday's game. Right-hander Zach Neal also was promoted and lefty reliever Daniel Coulombe was optioned to Nashville.
To make room for Neal on the 40-man roster, Eric Sogard was transferred to the 60-day disabled list.
Lowrie fouled a ball off his shin Monday night. X-rays were negative but the infielder was in obvious pain.
