The Arizona Diamondbacks attempted to solidify their offensive attack in 2012 with the addition of LF Jason Kubel. With Justin Upton entrenched in RF and Chris Young possessing a nice speed/power combo in CF, that means Gerardo Parra is regulated to 4th outfielder duties.
Kubel is a left-handed batter that will be turning 30 years old in May and is coming off a year in which he hit .273/.766. The year before only .249/.750. He had one monster season with the Twins in 2009 batting .300/.905 with 28 HR and 103 RBI, but other than that hasn't be an offensive stud during his 7 MLB seasons. The Snakes signed him for 2 yr/$15M. His defense leaves much to be desired (-41.8 UZR over past 2.5 seasons). He's a nice role player that when healthy can provide some pop and run production, but did Arizona need him?
Parra is coming off a Gold Glove effort in 2011, and the 24 year old improved at the plate batting .292/.784. He does not possess the power that Kubel does, but his defense and speed are much better. He's not even arbitration eligible, so he's much cheaper than Kubel as well (he'll likely make around $500K in 2012). He's always hit for average in the minors (.314) too.
Kubel- power, run production, costly.
Parra- cheap, defense, speed, batting average.
Why did the Diamondbacks sign Kubel again?
