Projecting Matt Garza at Wrigley Field
The addition of Matt Garza to the Cubs rotation looks like an upgrade in a vacuum. On the surface, Garza appears to be a decent pitcher, holding a sub-4.00 ERA with a healthy 200+ innings each of the past two seasons. A young pitcher heading into his prime years, Garza does sport a varied pitch repertoire while relying mostly on his mid-90s four-seam fastball. Yet, though Garza may be a staple in the Cubs rotation and more reliable than the enigmatic Carlos Silva, he is anything but a potential ace in a rotation absent of aces.
As Dave Cameron explained, Garza’s approach in relying heavily on four-seam fastballs comes at the risk of surrendering home runs, and his relatively low home-run to fly-ball ratio for a fly-ball pitcher is one factor for his sub-4.00 ERA seasons. What I am concerned about is what I feel some optimistic Cubs fans (yes, they exist) are ignoring: Garza’s fly-ball tendencies are ill-suited for Wrigley Field, and his Tropicana-depressed HR/FB ratio will be exposed in 2011.
