With some free-agent contracts, the fine print can be revealing.

Right-hander Ryan Madson agreed to a one-year, $3.5 million deal Wednesday with the Los Angeles Angels. But Madson can earn as much as $7 million if he remains healthy and emerges as the Angels’ closer.

His contract includes five roster bonuses that could add up to $2.5 million and four bonuses for games finished that could add up to $1 million, according to a source with knowledge of the contract.

Madson, 32, had Tommy John surgery last April, but his agent, Scott Boras, believes he can ready by Opening Day and the Angels share that optimism, sources say.

Madson will receive his roster bonuses as long as he does not suffer an injury related to his right arm; if he went on the disabled list with say, a hamstring or groin injury, the days would not count against him.

The way the contract reads, Madson would receive $500,000 at each of the following thresholds — 45 days, 90 days, 135 days and 180 days (a full season) — as long as he is not on the DL with an injury to his arm.

He also would receive $250,000 at each point if he finishes 35, 40, 45 and 50 games — thresholds that he could reasonably attain if he established himself as the team’s closer.

Right-hander Ernesto Frieri and lefty Scott Downs are among the Angels’ other options for the ninth inning.
