Here is my Pirates Diamondbacks free pick: Offense has the edge in this matchup.
Pittsburgh games have been trending higher scoring lately, and weak pitching continues to create opportunities for opponents. Their ERA ranking near the bottom of baseball says plenty.
Arizona has the bats to capitalize as well, ranking near the top in batting average and on-base percentage. So why expect a quiet game?
Additionally, Chase Field has produced plenty of offense in spots like this, especially when shaky pitching enters the equation. Quick note, hitters should be comfortable here.
Runs should stack up.
This profiles as a game with offense on both sides.
Even so, the total still feels reachable based on the matchup data and current trends. My MLB betting system tells me the Over 8 is the play.
