Hi, I would love it if you could do an analysis of 24 year old LHP Jon Lester, his mechanics and stuff. To my untrained eye, he seems to have an especially nice, easy delivery, and I recall reading scouts raving about his smooth and effortless mechanics and great arm action since he was a prospect. What say you? Are they really that good? Also, his mechanics are actually a little different this year than they have been in the past, as the pitching coach John Farrell had him eliminate putting his hands over his head in his windup, to simplify his delivery. It seemed to help him improve his command this year.
We all know about his illness and we know now he was pitching with diminished stuff for a while because of it. It may have affected his command as well. This year, his stuff was all the way back, probably better than ever. The velocity increased on all his pitches steadily throughout the year, because he added about 20 pounds to his frame. By the end of the year he was showing a 93-96 mph 4 seam fastball, as well as a sinking fastball (newly added pitch this year, actually a one-seamer), cutter, curveball, and occasional changeup. According to Fangraphs he throws his cutter at the second hardest velocity (88.4) of starters who throw that pitch more than 10% of the time.
 I am curious to see what you think of his changeup, as he used it very little this year, but has been described as a good pitch in the past by scouts. I was wondering if you think if it could have the potential to be more with more consistency, or if it's a show-me pitch. It seemed like a pretty decent changeup to me, when it was on, but he just didn't seem to have much confidence in throwing it.
The Red Sox decided to take the calculated risk of having him increase his workload from his previous high by an additional 70 innings this year because they felt he was especially durable, citing his size and sound mechanics.

Do you think he has a good chance to enjoy a long and healthy career?

 I am a newbie to this site, but I have found it very fascinating so far, and look forward to learning more about this essential but slightly mysterious facet of the game. Thanksalot!
