Knizner went 1-for-3 with a home run, two walks, two RBI and an additional run Wednesday in the Cardinals' 14-8 win over the Pirates.

Knizner connected on his first career home run during the Cardinals' big nine-run second inning, which proved to be the difference in the high-scoring contest. The rookie has been working as the No. 2 catcher behind Matt Wieters lately, but Knizner will likely be optioned to Triple-A Memphis when Yadier Molina (thumb) likely returns from the 10-day injured list at some point in August.
