Since the Basic Agreement prohibits teams from trimming a player's salary by more than 20 percent, teams tend to non-tender arbitration-eligible players, thus sending them into the free-agent market -- because they don't want to pay them the salary they'll command the following season.
The only player seemingly on the bubble was Williams, who's in his second year of arbitration and pitched mostly in long relief last season. But the 30-year-old right-hander will be back, perhaps competing with Garrett Richards for the fifth spot in a rotation that still needs to be solidified.
The Angels owe about $100 million to nine players in 2013 -- Vernon Wells, Jered Weaver, C.J. Wilson, Albert Pujols, Howie Kendrick, Erick Aybar, Scott Downs, Chris Iannetta and Ryan Madson -- plus $4.5 million for buying out Dan Haren's contract and trading Ervin Santana.
Factoring in MLBTradeRumors.com's arbitration projections for Morales ($4.8 million), Callaspo ($4.2 million), Williams ($1.9 million) and Jepsen ($1.1 million), that puts them at roughly $117 million -- plus salaries close to the minimum for the remaining 12.
