The 113 pitches he threw in that contest marked a season high for the Mississippi State product.

The Pirates eventually dropped that contest as a 156 road underdog, 5-2, while the combined seven runs failed to topple the 8 ½-run closing total. The ‘under' has now cashed during his previous four outings.

Maholm received a no-decision against San Francisco April 13 in his first start of the season.
