D-Backs OF’s Headed in Opposite Directions

For all of the club’s touted young hitting talent, the Arizona Diamondbacks’ offense has flat lined in 2009. “Boasting” the third-worst wOBA in the major leagues (the A’s and Giants are one and two, the M’s fourth- it’s a west coast thing), the D-Backs are off the sluggish 12-17 start, with a run differential of negative twenty-two.

Arizona’s center fielder and right fielder offer quite the contrast in terms of making good on that former top prospect status. While Justin Upton has been downright venomous to opposing pitchers, Chris B. Young continues to raise concerns about his control of the zone.

Upton, of course, is a hitting prodigy. The 6-2, 205 pounder dominated minor league hurlers several years older than him, including a 2007 tour-de-force that saw hit bat a combined .319/.410/.551 between High-A Visalia and AA Mobile.

After an understandable bumpy start in the bigs as a teenager (.277 wOBA in 152 PA during the 2007 season), Upton more than held his own in 2008. In 417 PA, he batted .250/.353/.463, walking at an impressive clip (13.2%) while posting a .347 wOBA. His K rate was sky-high (34%), but that’s nitpicking when one considers that most 20 year-old players are toiling in A-Ball or are sophomores in college.

In 2009, Upton is one of the few Arizona hitters not embarrassing himself at the dish. The 21 year-old’s .405 wOBA paces the club by nearly 40 points (Mark Reynolds is second, at .367). Upton has creamed the ball, with a .271 ISO that runs circles around last year’s already-outstanding .213 mark. While he has continued to draw free passes at a decent rate (10.5%), his Kingman-esque strikeout totals haven’t been as much of a problem. He’s whiffed 25.9% of the time, still a high number, but the progress in that department is encouraging. Overall, Upton has compiled 5.1 Batting Runs, which already tops last year’s mark of 4.1.

While Upton has been busy claiming his spot as one of the most valuable properties in the game, Young has been hard at work trying to solve the energy crisis. The solution? Swing and miss enough, and we’ll have all the wind power necessary to end dependence on foreign oil. The former Pale Hose prospect (the principal swag in the Javier Vazquez trade several years back) had a spectacular minor league career, with a .266/.355/.500 line that actually understates his performance, if anything (he slugged .545 in AA and .532 in AAA). However, his performance to this point has left some wondering, “is that all there is?”

Young is in the midst of his third full season in the majors, but his results have cratered. After posting wOBA’s of .331 in 2007 and .329 in 2008, the 25 year-old has managed a feeble .248 this year. Young has always swung and missed with frequency, but his stellar secondary skills (walks and power) were expected to make the contact concerns moot. That just hasn’t been the case to this point:

2006: 7.9 BB%, 17.1 K%
2007: 7.0 BB%, 24.8 K%
2008: 9.0 BB%, 26.4 K%
2009: 5.9 BB%, 32.3 K%

What’s strange is that while Young’s control of the zone would appear to be eroding, he has actually increased his pitches/PA in each full season (2007 to now): 3.8 in ’07, 4.0 in ’08 and 4.2 in ’09. His overall contact rate hasn’t changed significantly, either, hovering between 75-77%.

In 2009, however, it seems as though Young is making worse contact: his Outside-Contact% has jumped from 53.7% in ’08 to 65.3% this season (62.1% MLB average). Conversely, his Z-Contact% (percentage of contact within the strike zone) has tumbled from 85.3% to 79.2% (87.7% MLB average). He’s putting the bat on the ball more often on offerings off the dish, while coming up empty with regularity on the pitches that do cross the plate. Young is also getting jammed more often than any other major league hitter: his IF/FB% is 41.7%, nearly five points higher than second-place Rick Ankiel.

Young’s .238 BABIP surely isn’t helping matters, and given a decent line drive percentage (18.5%), you’d expect that number to climb. Still, Young is going to have to do better than a 0.19 BB/K ratio if he’s going to lean more toward Upton’s brilliance in right, as opposed to Conor Jackson’s similar brand of disappointment in left.
