Dayton had trouble locating his curveball this year, throwing it for a ball 42% of the time, which comes as no surprise as his ball rate pre-Tommy john in 2017 was also bad at 60%. The difference though between those two years is that he was able to generate a higher ground-ball- to-fly-ball ratio (71% to 29%) compared to this year, where it was the opposite way around with the fly-ball rate being greater than the ground-ball rate (54% to 46%). Because of this, he saw the average exit velocity and launch angle climb six and 17 points, respectively.
While his curveball had trouble generating whiffs, Dayton’s fastball found success, ending the season at a 29% whiff rate. However, this has always been the pitch that gives him trouble when it comes to the long ball, as it has allowed the most each season (tied with his curveball last year at 2). This can be attributed to its rather low 90 mph velocity and his inability to keep the ball from being elevated, with the fly-ball rate being north of 50% in every season.
Dayton’s fastball has average velocity but generates his most whiffs (10.4%). He varies the speed of his fastball from 88-94 MPH and throws it in the zone 56% of the time.
Dayton has a nice 12-6 curve that compliments his fastball well. It only generates 6.3% whiffs but a groundball 71.4% of the time and allowed only a .143 BABIP
