BRADENTON, Fla. — Jon Lester had much more to say about his changeup than he did about his future.

The left-hander threw 57 pitches in his third spring training start, and a makeshift Boston Red Sox lineup outslugged the Pittsburgh Pirates 15-14 on Monday in a 10-inning game that lasted 4 hours, 10 minutes.

Lester's outing came one day after Yahoo.com reported that he had agreed to a $30 million, five-year contract extension with a $13 million club option for 2014.

The Yahoo! Sports report cited an unidentified source close to the team. Lester, however, said no deal had been completed.
