Stat of the Day: Will Wily Peralta’s Groundballs Lead To Success In 2015?

by Eric Stashin (aka The Rotoprofessor)

Did You Know:
In 8.1 innings this spring Wily Peralta has recorded 17 outs on the ground and 0 outs in the air.


Peralta has always been an intriguing pitcher, aside from his 17 wins a year ago.  He showed the trio of statistics that fantasy owners look for from a starting pitcher, though that often gets overshadowed by the W:

  • Strikeouts – 6.98 K/9
  • Control – 2.76 BB/9
  • Groundballs – 53.6%

The groundouts vs. fly outs are extremely important, as his biggest issue a year ago was the long ball (1.04 HR/9).  That was even worse at home, as we would expect, with a 1.27 HR/9.

Even better he has shown more strikeouts this spring, with 7 K over 8.1 innings of work.  Obviously that doesn’t mean much, and the underlying stats from last season don’t necessarily show significant upside (8.5% SwStr%, 29.6% O-Swing%).  He did show more in the minor leagues, with an 8.5 K/9 overall and a 9.3 mark at Triple-A (over 177.2 IP), so growth in that department is hardly unreasonable.

The potential is there for Peralta to bring the total package, if his small spring sample is any indication.  He’s shown that upside before but now time will tell if he can fully translate it into the regular season.
