O’Day’s slider has been one of his primary offerings traditionally, garnering near double-digit pVals in past years. However, it’s dropped off in its effectiveness, and opponents battered it for a .344 batting average against. It also didn’t fare well against the long ball in a small sample size.
His four-seam fastball was his second-most used pitch, and it was his most effective at a batting average of .189 against. He commanded it well, walking none but striking out more than a third of the batters who saw it due to its above-average vertical and horizontal movement out of the sidearm position.
O’Day’s sinker is his last offering in the arsenal, which he threw less than half as much as any of his other pitches. Although it was in an extremely small sample size, he didn’t allow a single hit off his sinker. Due to his delivery, this heater gets an extra 20 inches of vertical drop compared to league average.
