The Angels agreed to terms with closer Ernesto Frieri ($3.8 million) and reliever Fernando Salas ($870,000) on 2014 contracts Friday, avoiding arbitration with the pair of right-handers.
But they were unable to agree to terms with new third baseman David Freese and reliever Kevin Jepsen before Friday's deadline for arbitration-eligible players to exchange salary figures with their clubs.
Both Freese, acquired from St. Louis in the Peter Bourjos trade, and Jepsen are under club control for next season, but if they are unable to agree to terms on contracts, they would go to arbitration hearings in February.
Freese, who hit .262 with a .340 on-base percentage, .381 slugging percentage, nine home runs and 60 runs batted in for St. Louis, asked for $6 million, and the Angels countered at $4.1 million.
Jepsen, who went 1-3 with a 4.50 earned-run average in 45 games and underwent a season-ending appendectomy in late August, asked for $1.625 million, and the Angels countered at $1.3 million.
The hard-throwing Frieri, 28, acquired from San Diego in May 2012, went 2-4 with a 3.80 ERA in 67 games last season, converting 37 of 41 save opportunities, striking out 98 and walking 30 in 68 2/3 innings.
Salas, 28, also acquired from the Cardinals in the Bourjos trade, split 2013 between triple-A Memphis and St. Louis, compiling a 4.50 ERA in 27 games in the big leagues and a 1.90 ERA and 12 saves in 22 games in the minor leagues.
Salas, who is expected to compete for a bullpen spot this spring, went 5-6 with a 2.28 ERA and 24 saves in 68 games for the Cardinals in 2011.
