Not So Fast: Is Eddie Rosario Already Losing a Step?
Image courtesy of Jesse Johnson-USA TODAY SportsWhen Rosario came up to the big leagues in 2015, he was raw as a hitter but both his speed and defense stood out. Fast forward two years, and it appears Rosario has turned a complete 180. Here is Rosario’s three-year trend in sprint speed, UZR/150 and BsR. Everything is trending the wrong direction.
In terms of sprint speed, Rosario has gone from the 32nd-fastest player in baseball in 2015 to 150th last season. That’s a drop from comfortably inside the top 10 percent to outside the upper third of all players. He’s lost exactly one foot per second on average over the past two seasons, which can be a huge difference when you’re tracking down fly balls in the outfield.
Below is a look at Rosario’s sprint speed the past three seasons compared to some of his teammates. He went from easily being the second-fastest player in this group to slipping down to fourth.
And here’s a look at Rosario’s numbers in relation to a handful of other players around his same age.
So what do we make of all of this? Well, the pessimistic approach would be to conclude that Rosario’s athleticism is already eroding. But he’s still only 26-years-old, so I find that a little hard to believe.
Is it possible that Rosario has played big parts of the past two seasons with undisclosed minor leg injuries that have sapped him of some of that speed? The only time Rosario has been on the DL was when he fractured his thumb in late 2016, but he’s surely played through a few scratches and strains.
What do you make of Rosario’s defensive and base running declines?
