However we adjust and normalize, the raw data is that Lopez has gotten to more-than-average balls over the course of 3,000 chances. If he is a bad second baseman, it's not showing up in terms of outs he makes, unadjusted.
BP's RATE stat has him as a 102 second baseman, lifetime, though weirdly down this year.
He is a 2B who has played a significant amount of SS, so that's one more piece of data that counts in his favor.
