The Pittsburgh Pirates ace, preparing for an opening-day start against the Chicago Cubs, walked in a pair of runs in a four-run second during a 5-0 loss, giving up four runs, four hits and the two walks.

Left-hander Wandy Rodriguez, the Pirates' No. 2 starter, pitched three scoreless innings. He then departed for San Juan to join the Dominican Republic for the World Baseball Classic.
