Pete Kozma went 3-for-4 with a triple, a double and two RBI against the Padres on Monday. Kozma hit just .232/.292/.355 in 448 at-bats for Triple-A Memphis this season, but he's 5-for-11 with three extra-base hits since his callup. He's not at all likely to keep hitting, but since he's a strong defender, he may well be the Cardinals' primary shortstop the rest of the way.
