Appreciate the analysis.
"Sánchez's out-of-zone swing percentage is 38.5 percent (9th percentile), so pitchers have no real incentive to lay a ball over the plate. If he can become more selective at the plate, he’ll have a better chance to put that violent swing to work."
This is extremely difficult to change in a hitter
When I'm trying to figure out if a batter is actually good, OBP is usually the first stat I check. Sanchez's OBP was never any good (average at best, in his best season)
