Ynoa almost doubled his changeup’s usage rate from before his injury, throwing it 13.25% of the time in 2019 compared to just 7% of the time in 2017. It wasn’t effective for him through, generating -4.0 pitch value this past season, by far the lowest value for this pitch of his career.
After missing the entire 2018 season with a right shin stress reaction, Ynoa returned to the majors with a slightly retooled arsenal. He basically stopped throwing his curveball at all, only using it 1.57% of the time compared to 5.6% of the time in 2017.
Ynoa reintroduced a sinker to his arsenal, splitting his fastball usage almost perfectly between it and a traditional four-seamer. His average fastball velocity dipped slightly because of it, down to 93.47 mph from 94.3 mph in 2017. His overall fastball pitch value dropped off a cliff though, down to -11.9 from -3.5 in 2017.
The slider was Ynoa’s best pitch in 2017 with a 2.2 pitch value, but its effectiveness didn’t return with after his injury, generating -1.7 pitch value in 2019. He also stopped throwing it quite as often, only 29.58% of the time compared to 37.2% of the time in 2017.
While he does have above average movement on his fastball, it doesn’t miss many bats (4.7% whiff rate), and he’s give up a .333+ BAA the past two seasons.
Despite below average movement, Ynoa gets a stell 45% out of zone swing rate and 17.5% whiff rate on his slider which is probably better suited as an off speed pitch than a breaking ball thanks to it’s subtle movement.
Ynoa’s changeup wasn’t terribly effective with only 13% out of zone swings an d a 7.5% whiff rate. He also gave up flyballs 60% of the time. He doesn’t throw it much and probably shouldn’t at this point.
