The Angels retained Mike Trout`s services for the 2013 season, but at what cost is unclear.

The reigning American League Rookie of the Year will earn $510,000, $20,000 above the major-league minimum. That figure didn't suit Trout's agent, Craig Landis, who responded on behalf of his client in a terse email to reporters.

"During the process, on behalf of Mike, I asked only that the Angels compensate Mike fairly for his historic 2012 season, given his service time," Landis wrote. "In my opinion, this contract falls well short of a `fair' contract, and I have voiced this to the Angels throughout the process."

The Angels were within their right to offer Trout whatever they wanted above the minimum. Players with zero to three years of major-league service time (Trout has one year and 70 days) do not have the same leverage as a player with three to six years' service time, who are eligible for arbitration. Players with six years of service time are eligible for free agency.

"The $510,000 salary was not the result of a negotiated compromise between Mike and the Angels," Landis wrote. "Because Mike has less than 3 years of Major League service and has not yet reached salary arbitration eligibility, the Angels have the right under the CBA to unilaterally impose a salary upon Mike, and they chose to do that today."
