Esteban lost some of his velocity, his fastball now tops out at about 91-92 (mixes speeds well), but he's developed a pretty damn good changeup. He also throws a slider that hit 84-86 mph. So far he's show unbelievable control, but it's doubtful he can keep it up. With the Sox's offense and the fact that he's been a good vs. other AL central teams means he could be a 15 game winner.
