Stephenson is a buy — real contact, results to match

His expected wOBA is .333, .018 above the league average, and he has 420 plate appearances — well past the point where that number becomes reliable. The important part is that his actual wOBA sits at .330, right in line with it, so nothing on the surface is being propped up by luck. His hard-hit rate has stepped up across the sample and now sits at 44.7% against a league average of 40.0%, and a 12.1% barrel rate is well above league. He does strike out 27.4% of the time, which will cost him some batting average in cold weeks, but the plate discipline underneath is sound: an 11.0% walk rate and one of the lower chase rates you will find. The contact quality is real and the sample backs it. Buy.
