Greinke has made 10 career starts in Petco and has a stellar 1.90 ERA there. That's his lowest figure for any of the ten parks in which Zack has thrown 40+ innings. Despite this, however, his record is a mediocre 4-1. with just one victory over his last four attempts. That came in likely the worst of those four outings, last September, when he allowed two runs over six innings, despite walking four batters, in a 3-2 Diamondbacks win. But he has never had a Game Score lower than 50 in Petco, and his last six starts in San Diego, covering three years now, have all been rated better than 60.
Fun fact. Who is the all-time leader by OPS for D-backs hitting in Petco, regardless of number of PAs? If you watched last night's game, you saw it, because the current leader is Jeremy Hazelbaker, whose PH triple gives him an OPS with the D-backs in San Diego of 4.000. But the second-place spot might surprise you too, not least because it's in a respectable 11 PA. It's Micah Owings, who was 7-for-11 with two doubles, for a career 1.455 OPS in Petco. If we keep a 10 PA minimum, the others in the top five are Phil Gosselin, Chris Johnson, Troy Glaus and... Randy Johnson, who was 5-for-11 with a double, for a 1.000 OPS.
Among current D-backs, the leader is someone not in the line-up tonight, Yasmany Tomas, who has a career line of 300/.364/.550, for a .914 OPS. Goldschmidt's .887 OPS is not far behind, with third place going to Peralta's .814 OPS. The worst figure here belongs to Nick Ahmed who has really struggled here: over his 11 games here, he has a slash of .139/.162/.167, for a .329 which is comparable to the .304 figure put up over 10 games by Brandon Webb. Hopefully, Nick will improve on that tonight, and along with a strong outing from Greinke, will secure us at least a split of the 10-game road-trip, with one game still to go.
