Rangers vs Diamondbacks Pick, Betting Analysis

By Derek Carty

THE BAT X is forecasting 3.36 strikeouts for Rocker compared to 4.00 strikeouts implied by the oddsmakers, so I believe there is value here.

If you take the under, you'd be projected to win 58% of the time, resulting in a 30% ROI. Based on a $100 wager, the expected value here would be $30.34. This play is good down to at least -111.

Pick: Kumar Rocker u3.5 Strikeouts (+125, bet365)
