Díaz is a buy — the contact is elite and still climbing

His hard-hit rate has stepped up across the sample to 48.1%, eight points above league, and his expected wOBA has climbed with it to .346 — .031 above league on 686 plate appearances, well past the point where that number is reliable. His actual wOBA of .350 tracks right with it, so the production is earned, not borrowed. The one soft spot is his BABIP at .316 against a league average of .295, and on 522 balls in play that gap is still luck — BABIP needs around 800 to settle. Some of the batting average will give back, but that is a cosmetic issue, not a skill one. A 14.3% strikeout rate and a 7.0% swinging-strike rate support a hitter whose bat is under control and getting better. Buy.
