Pirates vs Cardinals Pick, Betting Analysis
Pirates starter Carmen Mlodzinski is coming off two solid outings against the Giants and Rockies, giving up four runs in 11 innings combined.
His rival on the mound today, Michael McGreevy, is on an even better run at this moment. The Cardinals SP has pitched exactly six innings in each of his past four outings, giving up just one run in two games and none in the other two.
In those 24 innings, McGreevy allowed just 14 hits and fanned 21 batters.
While yesterday's 15-run game might scare some people off the under, this is a great option tonight, as our PRO systems suggest.
Pick: Under 8 (-119, DraftKings)
