This may seem odd to say, but until this series I am not sure the urgency was there for this team. It's like they didn't realize they were in a pennant chase. Leyland didn't even care enough in most series' to play the best lineups in the final game and gave half the team the day off.
The first 2 games of the series the Tigers played about as well as you could play. Great starts from Scherzer and finally a real good start from Fister. Scherzer's last two starts have been excellent. Real tough pitching from him even when he got into some trouble. First game of this series he got a lot of bad breaks in his final inning with a blown KO call to end the inning, an error, and a past ball. HE buckled down and finished it off with over 120 pitches for his 2nd straight start. Benoit and Valverde went in the 8th and 9th to just like you draw it up.
TODAY...still going on, but the Tigers came out and scored 7(!) runs in the 4th inning. Porcello once again came out and pissed it away like he did last game he pitched against the Indians. They scored 5 runs right after that and now in the 8th inning the Tigers are only up 8-7. Leyland actually made a good move though pulling him right away. He got ejected later on a blown call at 3B where Betemit was safe.
Regardless, this series the Tigers have shown they are ready to win this thing. Best I've seen them play and most focused all year.
