Birdsong (3-2) allowed five runs on five hits and a walk while striking out five over 4.1 innings to take the loss versus the Tigers on Sunday.
Birdsong has stumbled in consecutive starts since joining the Giants' rotation on a more firm basis, allowing 12 runs over his last 6.1 innings. His command was better Sunday with 51 of his 85 pitches going for strikes, but he gave up multiple home runs for the second outing in a row. The right-hander is now at a 5.40 ERA, 1.39 WHIP and 44:19 K:BB through 36.2 innings over eight starts in the majors. Birdsong is tentatively scheduled for a road start in Oakland for his next outing, though he may be on a short leash if his performance doesn't improve soon.
