Besides Barney, Samardzija and Wood, the other arbitration-eligible players tendered 2014 contracts include pitchers Pedro Strop and James Russell, infielder Luis Valbuena and outfielder Nate Schierholtz.
A total of 28 players from the Cubs' 40-man roster were tendered 2014 contracts, including 21 not yet eligible for arbitration.
With all the moves, the Cubs' 40-man roster now stands at 37 players.
Murphy, 30, who was arbitration eligible, agreed to terms on a $825,000 deal. He spent most of the season at Triple-A Iowa, where he batted .265. In 46 games with the Cubs, Murphy batted .255 and hit 11 home runs.
Kottaras, who also was arbitration eligible, signed a one-year, $1.075 million contract that includes incentives. Acquired last Tuesday from the Royals in a trade for cash considerations, Kottaras made $1 million last season. He is projected to back up Welington Castillo behind the plate.
According to MLBTradeRumors.com, Samardzija is projected to get $4.9 million in 2014, while Schierholtz is projected to get $4.4 million, Wood $3.6 million, Barney $2.1 million, Russell $1.7 million, Valbuena $1.5 million and Strop $1 million.
The Cubs already have committed $49 million to six players for 2014 and will be paying $14 million to the Yankees to cover the last year of Alfonso Soriano's contract.
The Cubs are keeping an eye on the now-expanded list of free agents. Last year, they signed Schierholtz after he was non-tendered by the Phillies, and the outfielder became a regular in right field. Schierholtz set career highs in home runs (21), doubles (32) and RBIs (68), and led the team with a .259 batting average with runners in scoring position.
Bard, once a dominant setup pitcher with the Red Sox, was claimed off waivers in September. At that time, Theo Epstein, president of baseball operations who knew Bard from his Boston days, said the Cubs were committed to the right-hander for the long haul. Bard had struggled after the Red Sox tried to convert him to a starter and battled a strained abdominal muscle this season.
When he joined the Cubs, Bard did not get into a game but worked on the side with pitching coach Chris Bosio. They recorded the sessions, even though Bard was unaware of the cameras as the Cubs hid one in the ivy and another in a door at Wrigley Field.
Bard, 28, appeared in three games in Puerto Rico last month, but retired only one of the 13 batters he faced. He walked nine, hit three batters and threw four wild pitches in those outings. The Cubs could still re-sign Bard, who made $1.8625 million this year.
Gamel, 28, sidelined most of this season because of a torn right anterior cruciate ligament, was acquired off waivers from the Brewers in early October. Lim, 37, signed as a free agent with the Cubs and appeared in six games in September.
