The Red Sox agreed to terms with outfielder/first baseman Daniel Nava on a one-year contract for 2015 on Thursday, thus avoiding arbitration.

The deal is for $1.85 million, according to multiple reports.

Nava, 31, served as the team’s Opening Day leadoff hitter last season before struggling at the plate and eventually being optioned to Triple-A Pawtucket. Upon his return to the majors, the switch-hitter posted much-improved numbers, raising his .130 average at the time of his demotion up to .270 by season’s end. He also hit four homers and drove in 37 runs.

With Thursday’s agreement, left-handed pitcher Wade Miley is the only unsigned Red Sox player eligible for arbitration. According to reports, Miley is asking for a raise from $523,500 to $4.3 million, and the team offered $3.4 million. It’s Miley’s first time being eligible for arbitration.

In addition, the Red Sox announced the signing of five players to minor league deals with major league invites to spring training for the 2015 season.

The players signed are outfielder Quintin Berry, left-hander Dana Eveland, first baseman/outfielder Bryan LaHair, right-hander Felipe Paulino and catcher Humberto Quintero.

All five have major league experience. Berry was a member of the 2013 World Series Red Sox team and was used in the postseason as a pinch runner on several occasions, stealing a base each time. Also of note, LaHair, a native of Worcester, was an All-Star for the Chicago Cubs in 2012.
