With Chris Tillman and Jake Arrieta pitching well for Norfolk, there has been some talk of replacing Jeremy Guthrie in the rotation after his wretched start last night against the Yankees, a game in which he gave up 6 Earned Runs in just 4.2 innings. But I think that's throwing out the baby with the bathwater at this point.
Guthrie's peripheral based stats:
FIP xFIP K BB HR
Guthrie '10 3.90 4.45 18 6 3
That is over 30.2 innings (second only to Kevin Millwood's 32.0 innings for Baltimore) and good for a WAR of 0.5 over 5 starts. (Also second on the team behind Brian Matusz's 0.7 WAR.)
The guy is pitching a little better than his ERA would lead you to believe and it's no fluke (a .302 BABIP is actually a bit higher than his average over the past three seasons). Even after last night, and we have to remember this Oriole fans, it was only one game, he is still the second most valuable pitcher on the team. In Millwood and Guthrie, the Orioles have two pitchers who can reasonably be expected to be at least league average and pitch into the 6th inning every night.
Have you seen the bullpen? Guthrie has value if for no other reason that he can eat innings. Hopefully Dave Trembley realizes that even if some of the fans don't.
