Jeffers is a buy — the contact is climbing and the discipline is real.

His hard-hit rate has stepped up across the sample and now sits at 41.0%, with a barrel rate of 10.4% against a league average of 8.0% — and 251 batted balls is well past the point where contact quality becomes reliable. The expected wOBA tells the same story: .340, .025 above league, stable over 365 plate appearances, and his actual wOBA of .350 tracks right with it, so nothing lucky is holding the line up. The plate discipline is what makes it hold together. He strikes out 18.1% of the time against a league average of 22.0%, walks 12.3% against 8.5%, and swings and misses on just 7.1% of pitches. That is a hitter controlling the zone while the power grows. Buy.
