The Process Versus The Orioles

Jake Arrieta

Entering his last start against the Rays, Arrieta had made eight starts, pitching 45 1/3 innings with a strikeout-to-walk rate over 2 and an earned run average of 4.17. In the five starts since (including versus the Rays), Arrieta has thrown 24 innings, has a strikeout-to—walk ratio just over 1, and has a 6.38 ERA. In the interest of fairness, a lot of that damage was one in a short start versus the Nationals, but he was also ran after 2 1/3 innings pitched against the Mariners after allowing four runs.

Jeremy Guthrie

Throughout his career, Guthrie has struggled versus left-handed hitters. So far in 2011, that isn’t the case. Guthrie is actually boasting a lower OPS against lefties than righties this year (by 11 points) and it isn’t fueled by a reduced batting average on balls in play either (his BABIP versus lefties is 70 points higher—at .310).

Brian Matusz

A big lefty, Matusz is the toughest matchup of the series. Matusz’ platoon splits are the opposite of Guthrie’s and more extreme (606 versus lefties and 775 against righties). Unlike Guthrie, Matusz’s fastball sits around 90 and won’t touch the mid-90s, but he’ll get grounders off of it and sets up his changeup well. He’ll also toss a curve against righties and a slider versus lefties.
