John Smoltz is one of the top Starting Pitchers in the league and has been for the past 15 years, except of course the few seasons he was the top Closer in the league.
He is still going strong at age 40 aside from a few aches and pains. I know he has some soreness right now but I think they are just being cautious and setting him up to start against them Mets next week. Smoltz is good for 12 to 15 wins a year and at least 200 innings barring any major injuries. Look for Smoltz even at age 40 to be the leader of this pitching staff again in 2008 along with Tim Hudson.
