Jered Weaver took a loss after allowing three runs -- two earned -- in 8 1/3 innings Friday against the A's. The Angels have fallen 3 1/2 games back of the Red Sox with losses the last two days. Weaver gave up a leadoff homer to Jemile Weeks tonight, but he was pretty terrific otherwise. The Angels just couldn't help him. A Maicer Izturis error gave the A's a run in the eighth, and a David DeJesus homer in the ninth made it 3-1 before Weaver was pulled. Weaver lost his chance to win 20 tonight, which could mean he won't make his start next week if the Angels are eliminated from postseason contention.
