There wasn't one thing that could be pinned on the loss Saturday night. Gary Knotts didn't pitch great, but certainly didn't lose it for the Tigers. The bullpen only allowed 1 run in 3-plus innings, certainly not bad. The defense didn't commit an error, and the offense put up a few runs.
No, on Saturday night, the Tigers didn't win, but mostly just because they were playing the New York Yankees.
Knotts went 5 2/3 innings, giving up 4 runs on 10 hits. Esteban Yan relieved him and allowed 1 run of his own, giving the Yankees their 5 for the game. Jamie Walker and Ugueth Urbina then shut out the Yankees for the final 3 innings.
Likewise, Orlando Hernandez had a very average game, 5 1/3 innings with 3 earned runs. He also walked 3 and struck out 6. But after he left, the Yankees bullpen buckled down and didn't allow a run - and only 3 hits.
