Based on the below, he will need to be cut soon, unless the Red Sox want to keep paying him $250,000 for being unproductive.
Base salary: $750,000
For every 30 additional days from 60 onward, he gets another $250,000 for each one.
** He is beyond 60, so the next trigger on this is about 20 days out.
Plate appearances: Every 25 appearances from 225 to 500, he will earn an additional $250,000
Based on above, he can earn up to $5M.
**He is at about 200 PA, including walks, etc.
Sizemore then has the opportunity to make up to another $1 million, based on his time spent on the active roster. It's similar to what Mike Napoli had to do in order to reach his full incentives in 2013 after his degenerative hip condition was discovered, albeit on a much smaller financial scale. If Sizemore can hit 60, 90, 120, and 150 days on the active roster for Boston, he'll earn $250,000 each time.
He also gets a quarter-million dollar bump for plate appearances -- this is the arena where being a starting outfielder, rather than a bench outfielder, matters for Sizemore's wallet. Every 25 plate appearances, starting at 225 of them and up through 500, Sizemore can pull in an additional $250,000, giving him the opportunity to rake in an extra $3 million overall from playing time. So, if he makes the Opening Day roster, spends 150 days on the active roster, and accrues 500 plate appearances, Sizemore will have earned $5 million, rather than his base of $750,000.
