Contreras is a buy — the contact is real and climbing

His expected wOBA is .331, sixteen points above the league average, and he has 582 plate appearances behind it, well past the point where that number becomes reliable. The contact quality backs it up: 90.3 mph average exit velocity and a 44.1% hard-hit rate, both above league, on 438 batted balls. That hard-hit rate has been stepping up across the sample, and his expected wOBA has moved with it. His actual wOBA of .324 sits just under the expected mark, so there is no luck inflating the line — if anything he has been unlucky. He strikes out just 14.8% of the time, well below the 22% league average. Production is earned here. Buy.
