What Will the Yankees Do To Help Junior Fernández?

Another Pirates reliever has been picked up by the Yankees, and his name is Junior Fernández, owner of 54 career innings pitched in the majors with St. Louis and Pittsburgh. This past season, he finished with a 5.79 FIP in 18.2 innings; his career FIP sits at 5.57, so he hasn’t had much success in the league so far. So what exactly do the Yankees see in him?
Like many relievers in the Yankees’ bullpen, Fernández throws high-velocity sinkers and boasts an above-average ground ball rate: 58.9%, a very similar clip as Jonathan Loáisiga. That all sounds very similar to another Yankees pickup from the Pirates: Clay Holmes. But Holmes’ sinker is of the turbo ilk that forces its way down with bowling ball action; this past season, the vertical movement on that pitch was 21% above league average. Fernández’s is much more vertical neutral. In fact, the comparison to Loáisiga is much more appropriate. The table below shows how Fernández’s sinker specs compare to Loáisiga’s:
Name | Pitch | Measured Spin Axis | Extension | Vertical Release | Horizontal Release | VAA | HAA |
---|---|---|---|---|---|---|---|
Jonathan Loáisiga | Sinker | 1:08 | 6.5 | 5.6 | -1.8 | -5.3 | 0.1 |
Junior Fernández | Sinker | 1:21 | 6.5 | 6.1 | -1.5 | -5.7 | 0.0 |
The two pitchers have similar extension, release points, and movement profiles. The entry into the zone in terms of horizontal and vertical approach angles isn’t all that far off either. Overall, we’re looking at very similar pitches, and Fernández throws his even harder by about a tick. This alone is a good starting point to explain why the Yankees were interested enough to scoop him up off waivers. Read the rest of this entry »
