Spring training gets underway this week and, for many players, the next few weeks will bring us an early peek at what to expect in 2017.
For young players, like Atlanta Braves rising star Dansby Swanson and Chicago Cubs slugger Kyle Schwarber, the pressure is on to see if they can live up to sky-high expectations.
There's curiosity surroundingBoston Red Sox third baseman Pablo Sandoval and Arizona Diamondbacksright-handerShelby Miller, as both could potentially be in store for a bounce-back season.
Who has the most to prove this season? Is it the highly-touted prospects, high-priced free agents or veterans looking to regain their form?
ESPN's Bradford Doolittle has his list, but now it's time to make yours.
While Sandoval and Cleveland Indians outfielder Michael Brantley are looking to return to form after injury-derailed seasons, players like Colorado Rockies first baseman Ian Desmond and Detroit Tigers pitcher Jordan Zimmermann are hoping to prove they were worth their large free-agent contracts.
Pitchers and catchers report to spring training on Feb. 13 and 14, while position players are scheduled to report between Feb. 16 and 20.
