Díaz is a buy — elite contact, sustainable skill.

His expected wOBA is .368 — .053 above league average — and he has enough plate appearances for that number to be reliable. His actual wOBA is .386, running a bit higher, but the difference is driven by a .349 BABIP that is still noisy at 294 balls in play. Some of that average will regress, but the foundation is real. His hard-hit rate has stepped up across the sample and now sits at 48.3%, well above the 40% league average, and his exit velocity is stable at 91.1 mph. He also strikes out just 13.7% of the time, elite plate discipline. The market may see a hot streak; the data sees a skill that has gotten better. Buy. 4 HR, 26 R, 31 RBI, 1 SB, .286 AVG — a deep-league asset with elite plate skills worth acquiring now.
