David Ortiz made his 575th plate appearance of the season today, boosting the value of his 2016 contract to $15MM, Peter Abraham of The Boston Globe tweets. The Red Sox held a club option on Ortiz for 2016 that vested for $11MM when the slugger hit the 425-PA plateau, and he has only been adding to his future salary ever since by making more and more plate appearances. Big Papi can max out his deal at $16MM in 2016 by reaching 600 PA, which seems like a foregone conclusion with two weeks left on the schedule.
