Fantasy Stats: .228 BA, 12 R, 5 HR, 22 RBI, 0 SB (131 PA)
So explain this one: Not only is Wilin Rosario's .237 BABIP nearly 70 points below his career mark of .305, it's also one of the 25 lowest in the majors, and yet his ground-ball rate actually is up dramatically from the low- to mid-40 percent range the past few years to a whopping 55.9 percent.
That sort of combination—elevated ground-ball percentage and a low BABIP—don't often go together as much as, say, an elevated fly-ball rate and a low BABIP. Simply, grounders tend to turn into hits more often than fly balls do, which is proved by a league-wide .240 average on the former and a .166 mark on the latter.
The key in Rosario's case, then, is noticing that all those extra grounders have taken the place of line drives. The 25-year-old's line-drive percentage has dipped to 13.7 (career 19.4 percent). That's not good news, but remember that Rosario missed two weeks with a nasty viral infection, so his batted ball data is a smaller sample size than most (and he also might not have been at full strength for some time). Plus, nobody is scoffing at five homers and 22 RBI from a catcher.
Ultimately, the grounders should start finding holes more often, and Rosario's batting average will climb. If he starts hitting the ball in the air or on a line a bit more, then his numbers can't help but get better in that Rockies' one-through-nine.
