OAKLAND -- The A's closed in on getting all their arbitration-eligible cases off their books Friday by agreeing to terms with four of the five players remaining on that list.

In the fold are right-handed reliever Luke Gregerson, shortstop Jed Lowrie, first baseman Brandon Moss and outfielder Craig Gentry. The only arbitration-eligible player still for Oakland is right fielder Josh Reddick.

Lowrie was signed for $5.25 million, Gregerson for $5.065 million, Gentry for $1.145 million and Moss for $4.1 million.

Those signings come a day after the club signed catcher John Jaso to a $2.3 million deal and closer Jim Johnson to a $10 million contract.

The A's acquired Gregerson from the Padres on Dec. 4 for Seth Smith. He figures to be one of the setup men for Johnson after going 6-8 with four saves and a 2.71 ERA in 73 games last year.

Gentry, like Gregerson, is new to the organization, having hit .280 with two homers and 22 RBIs in 106 games with the Rangers as a fourth outfielder in 2013. He had a .373 on-base percentage and stole 24 bases in part-time work.

Lowrie was one of the steadiest of the A's hitters last year, his first in Oakland after spending time with the Red Sox and Astros. He averaged .290 with 45 doubles, two triples, 15 homers and 75 RBIs. The 29-year-old switch-hitter was second in the AL in doubles, and the 45 doubles was the second-best total in Oakland history.

Moss spent most of the season at first base, but was moved into the outfield for a bit when Reddick was injured. He wound up with a career-best and team-leading 30 homers while driving in 87 runs despite playing in a platoon. Of his 115 starts, 106 came against right-handed pitchers.
