JD Sussman of Rotographs presents some interesting observations of Teheran in the starts of his that Sussman was able to watch this year. Most interesting is the Ublado Jiminez style arm thrust Teheran apparently adopted at the end of his windup and the slider that he added to his arsenal near the season's end in favor of his curveball. It was mentioned on this site a few weeks ago that a roving pitching guru was assigned to Teheran in August to "fix" his delivery, which corresponds to the author's observation that the arm-thrust seemed to have been eliminated in his last few starts. I can't recall with great detail how his mechanics looked in the spot-start he made against Toronto in June, but it would be interesting if anyone who has video can confirm or deny the presence of arm-thrust.
