Andrew Triggs’ Hidden Strikeout Appeal
It’s not easy to get strikeouts when you don’t get batters to swing much. It’s even more difficult when you avoid the strike zone.
Over the previous three years, a qualified starting pitcher has induced swings at a rate lower than 44.0 percent over the course of a season only 23 times. Of those, only Trevor Bauer, Jose Quintana and Tyson Ross have had a single season with a strikeout rate of at least 24.0 percent, and none has had more than one season with a rate that high. By contrast, there were only seven occurrences of a strikeout rate below 24.0 percent among the 23 pitcher-seasons with the highest swing rates over the same period. Bauer and Quintana both elevated their K-rates last season, and they were able to do that partly because they located their pitches in the strike zone at near-normal rates of 44.4 and 44.8 percent rates, respectively. Ross registered a 25.8 percent K-rate in 2015, even though he induced swings infrequently and displayed subpar control. However, no qualified starter was better than Ross at getting whiffs on pitches outside the strike zone that season.
