Lester's whip is 47th best in baseball while his era is 18th. So a bit of luck has definitely helped him. Also, he has really gotten his walks under control - BB/9 2006 - 4.76, 2007 - 4.43, 2008 - 2.99.
His Babip has actually gone up a tick from last year 2006- .332, 2007-.285, 2008 -.298
So what gives? Is this luck or is this a pitcher with good stuff learning to control it? Probably a little of both, but the Lance Armstrong of baseball is due for his era to start matching his peripherals stats.
One thing of note....how does one gain velocity on the fastball AFTER cancer?
Avg fastball speed: 2006 - 90.2; 2007 - 89.9; 2008 - 91.4
