Earlier this year, Bill Petti mentioned in his CLIFFORD work the single largest driver in a player’s wOBA collapse from one year to the next was Z-Contact%. Players that saw their Z-Contact% decline by at least 1.4% had a 1.68 times the odds of seeing their wOBA collapse that season than those that did not experience such a decline.

As with any correlation, nothing is a guarantee. Just because a player improves or declines with any one statistic does not guarantee that the results will behave in lockstep. The five players who saw their Z-Contact% improve the most in 2013 were Gerardo Parra, Everth Cabrera, Brandon Moss, Carlos Santana, and David Murphy. Parra, Cabrera, and Santana saw their wOBA improve by 1, 38, and 20 points respectively while Moss and Murphy’s dropped 33 and 80 points.

It was equally volatile on the other end of the scale. Raul Ibanez‘s Z-Contact% dropped 5.3%, yet his wOBA improved by 19 points. Chris Young‘s Z-Contact% dropped 6.2% from 2012 to 2013 as his wOBA dropped 36 points.  Marlon Byrd’s 6.7% decrease was the third-largest decrease in Z-Contact% in the sample size, yet his wOBA improved an amazing 148 points last season. The two largest declines in Z-Contact% from 2012 to 2013 had one thing in common – a last name.

The Arizona Diamondbacks had a disappointing 2012 season and the front office has identified key areas in which the team must improve. The outfield isn’t one of these areas, as the Diamondbacks now boast five players who could all stake a claim for a starting role, whether in Arizona or on another team.

They could conceivably make things work if everyone was retained, but that seems like a sub-optimal use of valuable resources. With platoons — both traditional and non-traditional — and injury risk, carrying four or five competent outfielders is often necessary. However, trading one or two of these players could solve issues elsewhere on the diamond. The team would still boast a solid outfield while improving in other key areas. But determining who to trade isn’t as straightforward, as non-performance factors must be taken into consideration.

The Diamondbacks currently have Justin Upton, Chris Young, Adam Eaton, Jason Kubel and Gerardo Parra under contract. Upton is the most talented of the group as well as the most expensive. Eaton is a top prospect under team control that played well in a small sample of September plate appearances. Kubel is a strong hitter who can’t run or field who is signed to a team-friendly contract. Parra is an average hitter under team control with excellent fielding marks. Young is a terrific defensive centerfielder capable of 20/20 production under team-friendly contractual terms.

The team is likely to retain Upton and play him in right field. The team also seems intent on playing Eaton in center field, which means that Young seems like the odd man out. He could shift to left field, but part of what makes him valuable would get eliminated in the process. Given his age, fielding skills, offensive pop and contract status, as well as the free agent market developing at the position, Young would instantly become a very attractive trade target if he were made available. Dealing him makes the most sense for the Diamondbacks, as he has become expendable with Eaton’s presence on the roster, and could extract the most value in return.
