Cardinals starting pitcher Michael Wacha tossed 5 2/3 scoreless innings Wednesday and was engaged in quite the pitcher's duel with Nationals starting pitcher Max Scherzer, who struck out nine over six scoreless innings.

Wacha allowed four hits and one walk, while striking out four. He lowered his spring ERA to 1.76 in his fourth spring start.

"I was happy with it," Wacha said of his performance. "[I'm] just continuing to go out there and working on the pitches and strikes, fastball command, down in the zone. Hopefully, I'm on the right track going forward from here."
