The lack of errors obviously works in Span's favor in the voting process, especially among managers and coaches who still view defensive ability through more traditional ways. Some have started to give more weight to advanced fielding metrics in recent years, but there are still some "old-school" coaches who will look at Span's 1.000 fielding percentage over his 1,300 2/3 innings played and give him an edge. Gomez made five errors in 408 chances over 1,242 innings this season, while McCutchen had six errors in 338 chances over 1,378 innings. Some of the key advanced metrics, however, give Gomez a clear advantage over the other two NL center fielder finalists. Gomez had a 24.4 UZR, tops among all major league center fielders by a wide margin, and a 2.78 range factor, ranking first among NL center fielders. (McCutchen, last year's Gold Glove winner, had an 8.4 UZR and 2.14 range factor.) These numbers are especially important this year. In past years, Gold Gloves were based solely on voting by managers and coaches in each league. But this year, Rawlings added a sabermetric component to the Gold Glove award selection process, as part of a new collaboration with the Society for American Baseball Research (SABR). The SABR Defensive Index will account for approximately 25 percent of the Gold Glove selection process, with voting from managers and coaches still carrying most of the weight. So it appears, at least based on an initial glance, that Gomez will get an assist from the sabermetric element. Span's shot at the award might also take a bit of a hit for another reason, one that really shouldn't factor in at all but sometimes does anyway. Of the three finalists for the Gold Glove for NL center fielders, Span posted the worst offensive season. The Gold Glove Award is handed out for defensive ability, but it seems that offensive production sometimes comes into play. McCutchen might win the NL MVP award after hitting .317/.404/.508 with 21 homers and 84 RBIs, while Gomez hit .284/.338/.506 with 24 homers and 73 RBIs. Span, meanwhile, posted a .279/.327/.380 line this season, with four homers and 47 RBIs. Offensive production might help some Gold Glove candidates, but it won't help the Nats center fielder. As anyone who watched him on a daily basis knows, Span had a tremendous defensive season. He covered lots of ground, rarely got bad reads on fly balls and made a handful of spectacular catches on the run. He deserved to be named a Gold Glove finalist and has a shot at the hardware. But it looks like he might come up a bit short this year.
