Adrian Gonzalez’s raw numbers are plenty good on their own: .274/.405/.559 with 37 homers and 85 RBIs in 139 games.
He ranks among the NL’s top five in homers, OPS, and times on base and is in the top 10 for on-base percentage, slugging percentage, total bases, and extra-base hits. And he’s done all that damage despite being intentionally walked 20 times while surrounded by the worst lineup in baseball.
On raw numbers alone he’s been one of the best handful of hitters in the league this season and the same was true in 2006, 2007, and 2008 as well. However, even those strong raw totals dramatically underrate Gonzalez’s bat because he calls the majors’ most pitcher-friendly ballpark home. Petco Park turns home runs into fly outs more than any venue in recent memory and the impact can easily be seen in Gonzalez’s splits.
At home this season he’s hit .230 with a .434 slugging percentage and .832 OPS while averaging one homer every 20.5 at-bats. On the road he’s hit .314 with a .671 slugging percentage and 1.082 OPS while averaging one homer every 9.8 at-bats. Add it all up and Gonzalez has been about 30 percent more productive with over twice as many homers away from Petco Park. And this season’s extreme splits are nothing out of the ordinary for Gonzalez, who has the following numbers in four years with the Padres:
G AVG SLG AB/HR Petco Park 307 .261 .440 24.3 Everywhere Else 311 .306 .583 14.9
Those numbers are pretty remarkable. When at Petco Park he’s hit .261 with a .440 slugging percentage and one homer every 24.3 at-bats. When not at Petco Park he’s hit .306 with a .583 slugging percentage and one homer every 14.9 at-bats. Stick him in just about any other ballpark, for any other team, and Gonzalez is a household name who gets tons of MVP votes every year, but Petco Park has cost him about 50 points of batting average and 10 homers per season.
