By adding Aaron Harang and Chris Capuano to a staff that already included Ted Lilly, the Dodgers now have three predominantly fly ball pitchers in their starting rotation. Throw in Clayton Kershaw, a less-extreme fly ball pitcher, and Los Angeles will be as reliant on its outfield defense as any team in baseball. Matt Kemp and Andre Ethier are fixtures in center and right, leaving only leftfield in question. The Dodgers re-signed Juan Rivera, 33, to a one-year deal; however, the 230-pound Rivera does not have great range and his defense has been declining over the past two seasons. The team would be better off, given its staff, allowing Tony Gwynn Jr. to take the lion's share of playing time. Gwynn was a superior centerfielder in 2009 and '10 for the Padres, saving 10 to 15 runs a year in less than full-time play, and he was above average for the Dodgers in a reserve role last year. In a neutral setting, Gwynn and Rivera are comparable players, each worth around a single win above replacement. To the Dodgers, though, Gwynn's ability to track down fly balls is more important than Rivera's low-OBP power.
