The Birds rallied but eventually fell to Boston 8-6 at Camden Yards on Monday night.
Tommy Hunter was given a three-run lead but gave it right back, allowing the tying run to cross the plate on a balk in the sixth inning. Hunter allowed five runs on nine hits in six innings, walking none and fanning three. Kevin Gregg came on in the seventh and was tagged with the loss after allowing two runs on three hits and a walk.
The Birds showed patience at the plate in the third inning against a struggling Clay Buchholz, who walked in two runs with the bases loaded. Chris Davis slapped a solo homer in the fourth to give the O's a 5-2 lead. But the Sox rallied, and the O's didn't score again until the eighth. They had a chance to tie or take the lead with only one out and runners on second and third, but Wilson Betemit popped-out and Nick Johnson struck out swinging to end the threat.
The O's (27-16) still hold sole possession of first in the division while Boston (21-21) is tied with New York for last. The two clubs go at it again later tonight; Brian Matusz takes the mound for the Birds.
