Billy Koch has realized his mechanics have been causing problems for him. Specifically, an improper leg kick was taking 5-10 mph off his fastball.
Koch threw side sessions that satisfied himself, manager Jerry Manuel, and pitching coach Don Cooper, prompting Manuel to say, ''Billy Koch is our lead man. He’s the guy, no doubt about that. He just had to iron out some things.’' Manuel did add, however, that Koch, Damaso Marte and Tom Gordon can all expect to get save opportunities as the season progresses. Sounds fairly committee-ish, and maybe that’s a good route for a team that has three guys who are capable. Don’t put a lot of stock in any of this right now, though, as Manuel’s job is in jeopardy.
