Tuesday Rockpile: Wilin Rosario Facts

Boom, baby bull

Wilin Rosario is a 23 year old rookie catcher - that is not the type of player we can properly define going forward. Yet Rosario has made very bold statements of who he is to Colorado fans and Rockies brass, and those statements have been extreme. Consider:

  • Rosario's home run last night gave him 24 in a Rockies' uniform. Ben Petrick had 23.
  • Rosario now owns a .277 ISO, which is easily the 2nd highest of any rookie catcher. Not in 2012...EVER. (h/t GiantsNirvana).
  • Rosario's 21 HR obliterated JD Closser's franchise record of 7 by a rookie catcher, set in 2005. He trails franchise icons Troy Tulowtizki (2007) and Todd Helton (1997) by three and four home runs, respectively.
  • Rosario has converted 26.3% of his fly balls into home runs. Only 2 MLB hitters with 200+ PA this season are better...Adam Dunn and Giancarlo Stanton.
  • Rosario leads all NL rookies in home runs and all MLB catchers in dingers with his 21.
  • Via ESPN's hit tracker, Rosario's bombs have had a very good distribution around the yard. Compare to another player whose game is built on power.
  • Last night's home run, which looked out off the bat, was his weakest home run of the season
Rosario's Month to Month Splits
So basically, Rosario has elite power. He also has a .291 OBP, thanks to low contact and low walk rates, which is a notable concern. As Resolution has pointed out though, those rates are trending in a positive direction. That table looked even better before he struck out three times last night.

Wilin Rosario has an elite tool at a premium position with an improving approach. That is the good news.

The bad news is that Rosario has 14 passed balls and has failed to block 42 wild pitches. Catcher defense is difficult to measure, but those numbers decrease pitcher confidence. He has thrown out 27 would-be base-stealers, 5th most in MLB, but his work behind the plate otherwise has been the question.

While his improving walk rates and steady power are nice, it will be critical to see how Rosario progresses defensively behind the plate. He does not profile well at first or third base, so the most important development for his bat might just be his defense.
