Samardzija made $2.64 million in 2013 and was projected by MLBTradeRumors.com to get a raise to $4.9 million in 2014. However, Wood could get the biggest increase. The lefty, who was 9-12 last season and posted career highs in starts and innings pitched, earned $527,500 in 2013 and was projected to receive $3.6 million this year.
Nate Schierholtz also is coming off a strong season in which he set personal bests in home runs (21), doubles (32), at-bats (462) and RBIs (68). The outfielder made $2.25 million in 2013 and was projected to get $4.4 million in 2014.
Barney, a Gold Glove finalist, received $562,000 last year and was projected to receive $2.1 million in 2014, according to MLBTradeRumors.com.
Other Cubs to file Tuesday included James Russell ($1.075 million in 2013; projected $1.7 million in 2014); Pedro Strop ($502,500 in '13; projected $1 million in '14); Luis Valbuena ($930,000 in '13; projected $1.5 million in '14); and outfielder Justin Ruggiano ($494,500 in '13; projected $1.8 million in '14).
A quick refresher on salary arbitration: Eligible players are those with at least three years of Major League service but less than six years needed to qualify for free agency. If a case goes to a hearing, the player and the team each present their case to a three-member panel.
The last time the Cubs had a hearing regarding a player was in 2010 when Ryan Theriot "lost" as the arbitrator ruled in favor of the team's $2.6 million offer over the $3.4 million bid submitted by the infielder.
