Mike Trout says he had no problem giving up a few years of free-agent freedom in exchange for lifelong financial security and a chance to win championships with the Los Angeles Angels.

Owner Arte Moreno would have liked to lock up baseball’s best young player for even longer. He says he met Trout in the middle on a record-setting contract that keeps the Angels’ star center fielder under the halo for another six seasons.
