The Process Versus Orioles Pitchers

Jeremy Guthrie

This worked last time, so here it goes again—pretend everything printed below is a lie:

Guthrie really works off the fastball, which sits around 91-93 MPH but can shoot up to the mid-90s when needed. He throws two pitches against righties, his fastball and a slider –which gets whiffs and grounders alike— while adding a changeup against lefties. Despite the change, he is considerably better against same-handed batters (700 OPS versus righties and 793 versus lefties over the last three seasons). Once a guy gets on base, he’ll curb the fastball usage just a bit. Shouldn’t be too much of a hassle with the Rays’ ability to stack left-handed batters against him early and often.

Brad Bergesen

Bergesen has issues with left-handed hitters. He tends to be more of a groundball guy than he has shown this season, but that could be because of a small sample size. He works off his low-90s fastball and will sling a slider and change depending on who is up. Frankly, the Rays should be able to touch him up again.

Jake Arrieta

I wrote this about Arrieta during the offseason:

Meanwhile, Jake Arrieta will likely claim the fifth spot in the rotation. He’s a well-built righty (think Wade Davis) who rides a low-to-mid 90s fastball hard and heavy. Arrieta’s secondary stuff needs improvement (left-handers in particular teed off to the tune of .315/.394/.505), but the Orioles are probably pleased with the numbers turned in over his last eight starts versus those of his first 10 (3.78 ERA and 1.80 K/BB versus 5.47 ERA and 0.76 K/BB).

So far in 2011, Arrieta has continued the uptrend with an increase in strikeouts, decrease in walks, and increase in effectiveness versus left-handed batters. Maybe those are small-sample mirages backed by pitching against the Twins, Royals, and Mariners in three of his eight starts.
