Koehler will open the season as the Marlins' No. 4 starter, MLB.com reports.
EDGE Analysis
A comebacker to the elbow in a minor league game earlier in the week left Koehler with a bruise but did not affect his pitching schedule in any way. Koehler, who allowed six earned runs with a 9:5 K:BB in 13.1 innings with the big club this spring, is lined up to make his regular-season debut April 9 at Washington.
