The Trevor Cahill trade was the first move that Billy Beane made in the offseason, it sent (RHP) Trevor Cahill and (LHP) Craig Breslow to Arizona and in return Oakland received (RHP) Jarrod Parker, (OF) Collin Cowgill and (RHP) Ryan Cook. I originally graded this trade as a B+, citing a slight concern in Jarrod Parker’s control issues.
Jarrod Parker has been the pitcher the A’s had hoped he would, he has started in 11 games for Oakland and of those 11 games he has only surrendered 3 runs or more twice. Parker currently holds a 3-3 record with a 2.70 ERA over 66.2 innings. Although he only has 3 wins on the season, it does not reflect how well he has done so far.
Parker has a 1.9 WAR, which ranks 13th among AL starting pitchers. He has a .255 BABIP and a 3.50 FIP, although his xFIP of 4.41 is pretty poor. Control continues to be a slight issue for the young right-hander, he has a 4.32 BB/9 rate and 1.53 SO/BB ratio.
Collin Cowgill, who was just placed on the DL yesterday with a sprained ankle, has played in 32 games for Oakland. In 108 PA he has a .271/.343/.313 slash line with a .655 OPS and .286 wOBA. He has 1 HR and 9 RBI with 3 SB.
One of his biggest issues is his plate disciple, having only a .46 BB/SO ratio. It’s not really clear whether or not Cowgill will ever be an every day outfielder for Oakland, but he is definitely good enough to be a 4th outfielder for the A’s.
