Granting that baserunning stats are pretty wonky, I don't think there's agreement that he is definitely a positive value baserunner. Over the past three years, BPro has him at negative value twice and positive value once, Fangraphs gives him a positive value three times, and B-R has him negative twice and neutral once. That's 4 negative, one neutral, and 4 positive. Tough to be more nebulous than that. There is so much action revolving around Villar on the bases that I think it's difficult to give him a solid observational grade spanning the course of the year either. Some people obviously feel pretty strongly about him, in both directions. I honestly don't have a strong handle on who is right.
