David Ortiz says he plans to return to the Boston Red Sox next season after a vesting clause in his contract kicked in Saturday night with his 425th plate appearance.

Ortiz is now guaranteed a base salary of $11 million for 2016.

"It means I'm going to be here next year," Ortiz said. "Nothing different. When I signed this contract, I think as you're getting older you've got to earn things. Different than just getting away with things when you are younger.

"We agreed on that. I think I earned it, and come back next year."

Only 10 position players in Red Sox history have played past their 40th birthday, and only three have played in as many as 100 games past that age: Carl Yastrzemski, who played 446 games; Ted Williams, 216; and Bing Miller, 109.

Ortiz turns 40 on Nov. 18.
