Jon Lester

At 6-foot-4 and 190 pounds, Lester looks like a big leaguer. He is athletic, swings the bat well and runs well enough to be considered a top position prospect, but scouts see him first as a pitcher. He has one of the best lefthanded power arms in the country. His velocity has been up and down this spring, ranging from 88 mph on the day he threw a perfect game to a high of 93; he is aggressive with the pitch and holds his velocity well. He could add another 2-3 mph on his fastball because he is projectable. His curve is below-average now but has a chance to be a solid pitch. Committed to Arizona State, Lester could be a prime target for the Mariners, who have the 28th overall selection.
