Danny Duffy’s Greatest Game
Perhaps lost a bit in the trade-deadline shuffle, Kansas City left-hander Danny Duffy pitched one of the very best games of the year this past Monday. On the road against Tampa Bay, he had a no-hitter going until the eighth inning. By the time that inning had ended, Duffy had recorded 16 strikeouts against just one hit and one walk. After a fairly mediocre 2015 season spent mostly in the rotation, Duffy looked to be the next in line to become a very good reliever on a Royals team that has had its fair share. For the first month of the season Duffy pitched quite well out of the pen, but since the middle of May, he’s been a part of the rotation. Jeff Sullivan chronicled Duffy’s rise in the middle of June, noting in particular the lefty’s ability to throw for strikes, and hitters’ general inability to hit those strikes.
The numbers Sullivan cited in his post six weeks ago have remained good since then. Danny Duffy is generally a strike-thrower, keeping the ball in the zone 53% of the time this season, a figure which ranks sixth out of 95 qualified pitchers. Nor is he necessarily pitching to contact, however: his 78% Z-Contact rate is third in baseball behind only knuckleballer Steven Wright and Max Scherzer. Hitters haven’t fared too much better outside of the zone: his 56.6% O-Contact rate is 13th among qualifiers. His overall contact percentage (72%) and swinging-strike percentage (14.3%) sit behind only the figures produced by Jose Fernandez, Clayton Kershaw, Michael Pineda, Max Scherzer, and Noah Syndergaard. His 62% first-strike rate is good, but closer to the middle of the pack.
In Duffy’s brilliant game against he Rays, his first-strike percentage was actually a tad lower than normal at 53.9%, and his zone percentage was just a bit under 50%. Where Duffy excelled was getting the Rays to chase the ball outside the strike zone. Of the pitches outside of the strike zone, Rays batters swung at 44% of them and made contact on just 20% of swings.
