Scout’s note

Coby Mayo is a 24-year-old third baseman from Coral Springs, Florida, a 6-foot-5 fourth-round pick whose career line sits at .207 with 26 home runs in 197 games. The last 14 days tell you why clubs keep patience with him: a .290 average and .861 OPS, the bat waking up after a slow start to the year.

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.

Two sources, read a month apart, put this guarantee at the same dollar. That is the check, and it passed.

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.

The Wire

On the field: Coby Mayo ranks first in SLG (.746), OPS (1.109) and OPS+ (204) vs LHP, tied for lead with 14 HR.
