2005 supplemental first-round pick Tyler Herron threw six scoreless innings Sunday for low Single-A Quad Cities.
Herron is 6-4 with a 2.92 ERA, 46 H and 59/12 K/BB in 61 2/3 innings. The Cardinals have been quite careful with the 20-year-old, but he’s steadily turning into one of the team’s best pitching prospects. He gets quite a few grounders with his sinking fastball, and he also has a pretty good changeup. He could be a future No. 3.
