The Pittsburgh Pirates (38-51, 12-30 Away) went through their best period of the season, during which they won six games in a row and swept the New York Mets and St. Louis Cardinals, without allowing a single run to the Cards.

Pirates vs Mariners Prediction

The Mariners won seven of the previous ten H2H encounters, and although I am leaning toward them in this one, I will opt for the Over instead. I know that betting on Over when the Pirates are involved is tricky, but the run total is now high (7.5), and I am not impressed with the way Luis Castillo and Mike Burrows play of late. Castillo allowed multiple runs in four of his previous five starts, and although Burrows had better numbers in June (a 2.73 ERA), he will be under heavy fire from Cal Raleigh and co. Three of the last four H2H duels went Over. Go with Over again.
