It’s not Larry Walker or Todd Helton, Matt Holliday or Troy Tulowitzki. From 2006 to 2011, Chris Iannetta should have been the Rockie the Giants feared most. He hit .338/.510/.586 against them in 201 plate appearances. In fact, Iannetta’s 1.096 OPS against the Giants was so much greater than his .788 OPS against all opponents as a Rockie, that he also qualifies as the Rockie who most outperformed his expected OPS (by .308) when facing Giant pitching. Maybe I wasn’t paying enough attention to the Rockies all those years, but I didn’t expect this result. I expected the best hitter against the Giants to be Ellis Burks or Larry Walker. (The complete table is here.)
Other points of interest:
Brian Sabean has a reputation for acquiring guys who have done well against the Giants, and Ellis Burks, who played with the Rockies from 1994 to 1998 and for the Giants from 1998 to 2000, certainly is a datapoint in support of that reputation. As a Rockie, Burks hit .295/.399/.589 against the Giants.
Which Rockie hit worst against the Giants in at least 100 at-bats against them? That would be Juan Uribe, who in 134 plate appearances from 2001 to 2003 hit .159/.195/.278 against the Giants. (He had an OPS of .706 against all teams.)
