Athletics' Nick Kurtz: Back in action Tuesday

Kurtz (oblique) is starting at first base and batting leadoff Tuesday against the Cardinals.

The rookie first baseman is back in the lineup Tuesday after missing the previous three games due to oblique discomfort. Kurtz will attempt to get back on track after going 4-for-20 with five walks, a homer, five runs and nine strikeouts in the nine games preceding the injury.
