Marte is a buy — contact is climbing and the skill is real

His expected wOBA is .347, and that is .032 above the league average of .315 — with 551 plate appearances, his sample is well past the point where the number becomes trustworthy. His hard-hit rate is 41.9% against a league average of 40.0%, and it has stepped up across the season; his xwOBA has climbed the same way. He strikes out just 14.7% of the time, far below the league's 22.0%, so his batting average has a high floor even when the bounces go against him. His actual wOBA of .330 trails his expected mark, meaning the surface line has not caught up to the contact yet. The skill is earned and still improving. Buy.
