THE BAT X is forecasting 3.35 strikeouts for Clay Holmes 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 31% ROI. Based on a $100 wager, the expected value here would be $30.57. This play is good down to at least -112.
