Marte is a buy — the contact is climbing and the sample is real.

His expected wOBA is .349, 34 points above the league average of .315, and 624 plate appearances is nearly four times the sample needed for that number to be reliable. The actual wOBA is .323, so luck is not inflating the line — if anything, the results are trailing the contact. The contact quality has been stepping up across the season: a 43.0% hard-hit rate and 9.4% barrels, both above league, on 481 batted balls. The strikeout rate is 13.8% against a league average of 22.0%. He is not giving away at-bats while he waits for the bounces to catch up. The bat is doing real work and the results are starting to follow. Buy.
