As the Giants and Pirates prepare to clash in the NL Wild Card, both teams have a secret weapon peeking out from behind the bullpen screen.
The A's took a 7-3 lead to the bottom of the eighth, but couldn't hold on, losing to the Royals on a walk-off in the 12th inning on Tuesday.
Travis Ishikawa was the Pirates' Opening Day first baseman but in a strange turn events, he'll play left field against the Pirates on Wednesday.
Buster Posey and Andrew McCutchen are both NL MVP winners, but the two have a lot more in common and go back a lot farther than that.
Geovany Soto should prove useful at limiting the fleet-footed Royals on the basepaths. The only concern is that he's never caught Jon Lester.
