Daniel Descalso and Pete Kozma weren't done mystifying baseball after they keyed the St. Louis Cardinals' comeback in Game 5 of the NLDS, apparently. Back-to-back doubles in the fourth inning started the Cardinals' four-run rally against Madison Bumgarner and the San Francisco Giants, with Descalso scoring on Kozma's and Kozma, after stealing third base, scoring on a base hit from Jon Jay. The Cardinals probably don't need their infielders to each turn into Vladimir Guerrero, but it's helped.
Kozma's run has been more surprising just because he was so ineffective in the minor leagues, but Descalso's string of extra-base hits is almost equally unlikely. He slugged just .324 across 374 at-bats in 2012, with 10 doubles, seven triples, and two home runs.
That's 21 extra-base hits, or one every 18 at-bats. In the postseason he's now got four, or one every six at-bats. The Cardinals will be looking at middle infielders in the offseason, even with Rafael Furcal back, but Kozma and Descalso both have done their best to make a case for time in the postseason.
