Yes he is a low 90's pitcher 90-92 on a good day.
One reason for the drop in velocity is a lack of conditioning that also affects his stamina.
The key to his 2003 success was an improved slider. When he's able to throw a sharp slider with good command, it helps set up his other pitches. He's not afraid to throw inside to keep hitters off the plate. Ponson used to throw an average forkball, but recent elbow and shoulder woes have forced him to abandon the pitch. Without the forkball and the velocity he once had, he needs to keep the ball down in the strike zone to stay out of trouble.
Bottom line, he's a fat fuck who doesn't care enough...he got his big contract, the guy is punk, who wants to drink beer , not pitch in October.
