3 things to watch: Back end of the rotation
Nobody knows how this will pan out heading into Cactus League play, but that doesn't mean there isn't a lot of promise. Felix Hernandez and Hisashi Iwakuma will lead the group, but the options behind them are less proven. James Paxton started in only 13 games last season and put together a 3.04 ERA. Twenty-one-year-old Taijuan Walker (pictured) has been on the top-prospect radar for several years but has had trouble staying healthy. And a trade to acquire 32-year-old J.A. Happ from the Blue Jays adds depth.

3 things to watch: Nelson Cruz's impact
Nelson Cruz hit an MLB-leading 40 homers in 2014 for Baltimore, and while no one's expecting a repeat of that number, he should bring much-needed punch to the line. He'll likely get the bulk of his at-bats as designated hitter, with limited time in the outfield. Dustin Ackley and newcomer Seth Smith are likely to flank Austin Jackson in the corner outfield spots, with free-agent signee Justin Ruggiano likely to be a platoon partner.

3 things to watch: Mike Zunino at the plate
Locking down the starting catching job despite batting .199 says something about what Mike Zunino brings behind the plate. Zunino was masterful in managing his pitchers last season. But the Mariners are hoping he can develop into a more well-rounded player by being less of an automatic out at the plate. He was second on the team last season with 22 home runs, so a change in his all-or-nothing approach might yield some overall gains.
