SEATTLE -- As the countdown begins to the start of Spring Training, it's time to zero in on what to expect when the Mariners gather in Peoria, Ariz., for the first time under manager Scott Servais. We'll look at all the moves made by new general manager Jerry Dipoto and what to expect when pitchers and catchers report on Feb. 19.
In the coming days, we'll have a seven-part series looking at everything from players on the rebound, new guys in camp, prospects to watch, projected lineups, the three biggest questions facing the club this spring, key dates and things to look for and finally the scene in Peoria as players gather for the first workout.
Today's installment focuses on players on the rebound, which in the Mariners' case is a fairly significant factor as Dipoto has brought in a number of buy-low candidates who have been solid contributors on previous teams, but were available largely because they didn't perform up to expectations in 2015.
Here are seven guys the Mariners hope can bounce back in 2015 after either underperforming or dealing with injuries last season:
C Chris Iannetta: The 32-year-old played the past four years for Dipoto with the Angels, but got off to an extremely slow start last season and put up just a .188/.293/.335 line in 92 games, a big drop from his 2014 production of .252/.373/.392. The Mariners love Iannetta's veteran leadership as well as his career .351 on-base percentage, and they expect him to help bolster a team whose young catchers combined to hit just .159 with a .205 OBP last year.

CF Leonys Martin: Martin is an excellent defender, but lost his starting job in Texas last season to Delino DeShields while putting up just a .219/.264/.313 line with five homers, 25 RBIs and 14 stolen bases in 288 at-bats. But Martin is just reaching his prime at 27 and was a solid starter for the Rangers the previous two years, when he combined for a .268/.319/.374 line with 15 homers, 89 RBIs and 67 stolen bases. The Mariners consider him a key figure in their 2016 plans.
RHP Steve Cishek: Cishek saved 73 games with a 2.73 ERA and 158 strikeouts in 135 innings in 2013-14 with the Marlins, but ran into control problems last season, lost his closer's role and eventually was traded to the Cardinals. He pitched better in a setup role for St. Louis, with a 2.31 ERA in 27 appearances, and Dipoto pounced at the chance to sign an experienced 29-year-old closer on the free-agent market, with the hope that the side-arming right-hander solidifies the back end of a bullpen that struggled last year.

LHP Charlie Furbush: The 29-year-old southpaw was outstanding in the first few months of 2015, posting a 2.08 ERA and 0.646 WHIP in 33 appearances. But Furbush went on the disabled list in early July with tendinitis and rotator cuff issues in his left shoulder and missed the remainder of the season. Doctors determined Furbush didn't need surgery and he's recently begun throwing again, with the expectation he'll be fully healthy for the start of the regular season. If so, he'll be a critical piece of the bullpen as the lefty setup man.
RHP Justin De Fratus: The 28-year-old right-hander was outstanding for the Phillies in 2014, when he posted a 2.39 ERA and 1.082 WHIP in 52 2/3 innings over 54 outings. But pushed into more of a multi-inning role last year, things didn't go nearly as well (5.51 ERA and 1.550 WHIP in 80 innings over 61 outings). Dipoto signed him to a one-year deal for $750,000 and hopes to get him back closer to his earlier role and production.

RHP Ryan Cook: Another bullpen candidate coming off a tough season, Cook signed a $1.1 million deal after spending much of 2015 in the Minors for the A's and Red Sox. He was a 2012 All-Star for Oakland and a durable and consistent middle-inning stalwart for the A's from 2012-14, when he put up a 2.60 ERA with 17 saves with 197 strikeouts in 190 2/3 innings over 196 appearances.
C Mike Zunino: The 2012 first-round Draft pick will likely begin the season with Triple-A Tacoma as Dipoto feels the 24-year-old was rushed to the big leagues too quickly and needs to establish his offensive approach before resuming his Major League career. Zunino had 22 homers but hit just .199 in his first full season in 2014, then fell to .174 with 11 homers and just a .300 slugging percentage before getting demoted at the end of last August. If he hits well in Tacoma for an extended stretch, Zunino could work his way back into the catching picture at some point.
