Garrett Olson

Garrett Olson has pitched quite well this year, and looks ready to help the Orioles in spring of '08.

His line so far:
22 GS
128 IP
95 H
13 HR
39 BB
120 K
1.11 GO/AO
.208 BAA

However, looking at his last two games, I see he only had 1 IP, then 2 IP, with a poor line in the second game.  There is no mention in the game recaps of him having reached his IP mark for the year...

Anyone know Olson's status?  Injury, or other?
