The following 40-man roster players have less than five years service time and are out of minor league options. That means they must clear waivers before being sent to the minors, so the team would be at risk of losing them in attempting to do so. I've included players on multiyear deals. This list was compiled through MLBTR's sources. Next, we'll take a look at the NL East.
Braves: Cory Gearrin, David Carpenter, Ramiro Pena, Jordan Schafer, Anthony Varvaro
Carpenter is a lock for a bullpen spot. On Friday, Braves manager Fredi Gonzalez said of Varvaro, "Who knows? It's so early. If we had to break Spring Training today or tomorrow to start the season, I'd count on him. He'd be one of the guys in the bullpen," talking to MLB.com's Spencer Fordin. Gearrin is among a host of pitchers competing for two other spots in the pen; he told Mark Wiedmer of the Chattanooga Times Free Press in February his shoulder was 100% after being shut down for the final two months of the 2013 season.
Pena will serve as the Braves' primary utility infielder, and Schafer will be the fourth outfielder.
Marlins: Mike Dunn, Garrett Jones, Brian Bogusevic, Brad Hand, Jacob Turner
Beyond Steve Cishek, A.J. Ramos, and Dunn, the Marlins' bullpen picture is "extremely muddled," wrote Clark Spencer of the Miami Herald recently. As for the rotation, Turner looks like the team's fourth starter, with Hand, Tom Koehler, Kevin Slowey, and Brian Flynn in the mix for the last spot, according to MLB.com's Joe Frisaro. Spencer noted that Hand could land in the bullpen if he doesn't crack the rotation.
Jones was signed to be the team's primary first baseman. Bogusevic, acquired from the Cubs for Justin Ruggiano in the offseason, seems to have a leg up to become the team's fourth outfielder.
Mets: Eric Young Jr., Ruben Tejada, Carlos Torres
Young's spot on the team is secure. Tejada is the starting shortstop, though the Mets seem to be considering upgrades such as Stephen Drew or Nick Franklin. In the event they acquire someone, the Mets could entertain trading Tejada or just put him in a reserve role.
Torres is a lock for the Mets' bullpen, wrote Adam Rubin of ESPNNewYork.com a week ago.
Nationals: Jose Lobaton, Jerry Blevins, Tyler Clippard, Ross Detwiler
Detwiler will be on the Nationals' pitching staff in some capacity, either as the fifth starter or a member of the bullpen. Lobaton, Blevins, and Clippard are secure.
Phillies: John Mayberry Jr., Kevin Frandsen, Brad Lincoln
Mayberry and Frandsen were given guaranteed arbitration contracts, noted Matt Gelb of the Philadelphia Inquirer in February, giving them a leg up on bench jobs. Yesterday, Gelb wrote that Phillies GM Ruben Amaro Jr. "continues to dangle Mayberry this spring in trade talks." Mayberry is competing with Darin Ruf for a bench spot. A week ago, Chris Branch of The News Journal took a look at the Phillies' backup infield situation. Freddy Galvis is a near lock to make the team, with Frandsen battling Ronny Cedeno, Andres Blanco, Cesar Hernandez, and Reid Brignac for the one remaining spot.
Five days ago, Ryan Lawrence of the Philadelphia Daily News termed Lincoln to be "likely a favorite" for a bullpen spot, because of his option situation as well as past big league success.
