Left-handed pitcher Matt Strahm and the Philadelphia Phillies agreed Friday to a $15 million, two-year contract, a deal that could be worth an extra $1 million if he becomes a regular in the rotation for the National League champions.

Strahm gets $7.5 million in each of the next two seasons and can earn $500,000 annually in performance bonuses for starts: $125,000 each for 15, 20, 25 and 30.
