Scout’s note

Jahmai Jones has been at this since the Angels took him in the second round out of Roswell, Georgia in 2015 — a decade of bus rides for a .229 career hitter who has spent his age-29 season as a DH in Boston. But the engine sees a bat that isn't getting its due. His EV95 of 109.0 beats 87% of qualified hitters, and his results on contact fall further below the physics than 96% of them — a -0.0578 luck gap that, over just 101 balls in play, means he's hitting the ball far harder than a .206 average and .667 OPS can show. He's No. 10 on the breakout board. The sample is thin and the career WAR sits at -0.5, so the read is more promise than proof — but the contact is genuinely loud.

Current signals

The read: Jones is hitting the ball harder than 87% of the 406 qualified MLB hitters in our sample (EV95 109.0; league median 105.8), while his results on contact run further below the physics than 96% of them. Loud bat, quieter stat line — the breakout shape; he ranks No. 10 of 20 on the breakout board.

No hollow dots on his strip. He had not reached 100 balls in play by , so there is no earlier place to mark. He has 101 now.

A base salary under his own reading, and never subtracted from the cash figure above: a signing bonus lands in one and not the other, so the two disagree on most men without either being wrong. And the sheet does not mark which future seasons are GUARANTEED — a club option and a projected arbitration award are both just a number here, so read past the end of the deal as his forecast rather than as money owed.

The tax AAV above is his number under the CBA’s own rulebook, not the average we work out from Cot’s total. On a contract with deferred money the two come apart on purpose — and neither is subtracted from the other.
