Reliable sources have indicated that Jesse Litsch and Dustin McGowan despite having been injured for months and months are not really on schedule to break Spring Training with the team.
Even though the Jays have like 19 credible arms that they hope to catch lightning in a bottle with, it's never good when all of them are so young that the guys who lead the team with the most major league experience are the ones still in the infirminary ward!
Scott Richmond was profiled on TSN and spoke about how they would have to make up for the loss of the great Roy Halladay- and he said it would be tough but he's seen it done before in his many professional years of baseball, and if the pitching can keep Toronto in games, Toronto has a chance of winning the game every night. Halladay probably only contributed to an extra 5-10 wins a season, so a combined effort could certainly make up for that.
Toronto's rotation looks much like Tampa's in 2008- you've got sophomore Ricky Romero who could win 15 games, Ace Shaun Marcum who has proven he could win 15 games too, and if you had five guys who all won 10 games or more, I think you'd have a rotation that could compete in a very difficult American League East- Cecil, Richmond and Rez certainly seem capable of doing such.
If anything, maybe McGowan or Litsch can be great fill-ins when one of the fab five get injured.
