Koehler got the start in Wednesday's Grapefruit League game against the Astros, allowing one run on one hit and two walks over two innings with one strikeout.

EDGE Analysis

The 30-year-old posted a career worst 4.23 BB/9 and 1.47 WHIP last season, and Koehler will need to improve his control through the rest of spring training if he wants to remain in the competition for the Marlins' fifth starter job.
