With seven new high-profile additions, the Chicago White Sox will lift the lid on the 2015 season with a 25-man roster that is dramatically different than the one that opened last year’s campaign.

Because of the stark differences between the two rosters, expectations on the South Side are quite lofty. That leads to a natural question: Which players are the most important for success this season?

Well, that question can be answered in any number of ways, but we’ve identified five guys—two pitchers and one starter from each third of the lineup—who can sway the outcome on a nightly basis.
