Jesse Biddle, the top pitching prospect of the Philadelphia Phillies, had to miss a start because of headaches after he reportedly was hit on the head during a hail storm last Thursday.

The 22-year-old was kept out of Sunday's game as a precautionary measure. Biddle is 3-4 this season with a 3.18 ERA and 61 strikeouts in 56 2/3 innings.
