Diamondbacks Rays Free Pick: Over 8.5
Here is my Diamondbacks Rays free pick: Both clubs have produced mixed totals lately, but this matchup has a history of generating more offense than expected. That’s enough to grab my attention heading into tonight.
Tampa Bay has cashed the over in 3 of its last 5 games, showing its lineup is capable of putting pressure on opposing pitching staffs.
Arizona has leaned toward the under recently, yet that trend hasn’t carried over when facing the Rays. Their recent meetings have consistently produced enough offense to climb past the number, and that history is tough to dismiss.
Past meetings between these clubs suggest another game where runs won’t be difficult to find.
One hot inning can change everything.
Neither pitching staff has been dominant enough to scare me away from the total, especially with both offenses capable of putting crooked numbers on the scoreboard.
My MLB betting system expects another game that finishes above the number, making the Over 8.5 the best value on the board.
