Frnaklin Morales this year isn't a fluke.
His line is 8.3/.5/2.3/9.6 (H/HR/BB/K per 9). His FIP is lower then his ERA (2.8 vs. 3.12), both his SIERA and tERA are below 3. He wasn't lucky, he was really that good.
His BABIP is .319, it's a chunk above both the league and his own average. Even in his weak years he generated a sub .300 BABIP. His LOB% is at 75.8%, which is a bit high but understandable considering his low WHIP of 1.18.
I know people are complaining because of his 5.4% HR/FB, however in his case his HR/FB% is lying. Morales's FB% is 39%, just sightly above the league average, However 55% (!!) of the fly balls he generates stay in the infield. This is understandable considering the late movement his fastball has up in the zone and above it, hitters will often swing under it or pop it up. Because of his high IFFB% I believe a more appropriate stat for his line will be HR/OFFB% (Home-runs per outfield fly ball percentage). I calculated the league average HR/OFFB% to be at 13.15%, based on the stats I found on fangraphs. Morales HR/OFFB% stands at an average 13.13%. Again, stating Morales thus far wasn't lucky, he's really that good and even better.
In addition, his K/9 doesn't appear to be dropping. his O-contact% and especially his Z-Contact% are below average. And hitters are swinging at his pitches 48.8% of the time (League average is 46%), which isn't vastly beyond average but it does indicate his strikeouts are no flukes, and I predict they will stay high when starting as long as he goes the amount of innings that allow him to throw at the low to mid-high 90s.
Why, yes. I am a sabermetrics whore.
