Another day, another major White Sox transaction. General manager Rick Hahn had already acquired James Shields and banished Mat Latos this week, yet evidently his appetite for change wasn't satisfied. Instead, the roster churn continued on Friday, as starting shortstop Jimmy Rollins was designated for assignment and prospect Tim Anderson was promoted to fill the void.

Here are three things to know about the change.

1. Anderson is all over prospects lists

He entered the spring ranked first in the White Sox system by Baseball Prospectus and Baseball America, and was second on MLB.com's offering. Additionally, Anderson placed well on the universal lists, with Prospectus slotting him the highest at 19th. His well-above-average speed and bat-to-ball skills make him an intriguing top-of-the-order candidate -- albeit one whose on-base percentage could play light due to his aggressive approach. Meanwhile, his defense is good enough for him to remain at shortstop. As such, Anderson is expected to become a first-division starter -- a fancy way of saying a legitimate starter on a winning team.

2. He can only make things better immediately for the Sox

The good news for Anderson is he doesn't have to do much to represent an upgrade over the incumbents. Signing Jimmy Rollins to babysit the position while Anderson received additional minor-league seasoning was a smart idea, but the veteran didn't have much left in the tank. Rollins finishes his White Sox tenure with a .221/.295/.329 slash line -- numbers that had caused him to lose the starting job to Tyler Saladino, who is hitting just .247/.273/.376 himself. Anderson, for reference, was batting .304/.325/.409 in Triple-A.

3. The timing is not a coincidence

(And no, we don't mean because the White Sox had been struggling lately.) Whenever a top prospect, particularly a position player, is brought to the majors, one of the first questions is whether they'll someday qualify for Super Two status -- an inside baseball term that refers to the relationship between a player's service time and their earning potential. In the most basic sense, teams have financial incentive to delay their top prospects' arrivals, and they're more than happy to wait out the clock -- even though they're essentially taking money from their young players' pockets. Unfortunately, for Anderson, his call-up date means he won't have a say in his salary until after the 2019 season.
