Just to get you pumped, a couple of stats from sportsline.com

Lester allowed one run and three hits over 6 2-3 innings in his last
outing, a 4-3 loss to Toronto on Sept. 18 in which he did not record a decision.
The 23-year-old left-hander is 2-0 with a 2.70 ERA in four September starts
after posting a 5.67 ERA in his first six outings of the season.

Boston is 8-2 when Lester pitches this season.

Can you say two-and-a-half?
