Bleday is a buy — elite contact skill, no luck in the line.

His expected wOBA is .343 — .028 above the league average of .315 — and he has 487 plate appearances, well past the 160 needed for that number to be reliable. This is not a contact-quality mirage being propped up by results: his actual wOBA of .329 actually sits slightly below his expected mark, which means his production is earned, not gifted by bounces. His walk rate is 13.6% against a league average of 8.5%, so the on-base foundation is real. He rarely chases, and his barrel rate sits above league at 10.0%. The contact quality metrics are stable on 310 batted balls, and his expected wOBA has been stepping up across the sample. Buy.
