Here's a nugget regarding the Brewers, who emerged as surprise contenders in 2017 ...

That would be right fielder Domingo Santana. Last season, Santana enjoyed a breakout campaign, as he slashed .278/.371/.505 (126 OPS+) with 30 home runs and 15 stolen bases in 151 games. Santana's just 25 years of age, and as Rosenthal implies he's not eligible for free agency until after the 2021 season. Coming up through the minors for the Phillies and then Astros, Santana showed up on occasional top-100 prospect lists, so that breakout didn't come from nowhere.

The question is why the Brewers would consider moving a fairly young and controlled player who figures to be a big part of their efforts to keep contending. The likely answer is that they have a lot of outfield depth on the roster and on the way. To wit, they've got prospects like Lewis Brinson, Corey Ray, Brett Phillips, and Trent Grisham in addition to Santana, Ryan Braun, and Keon Broxton. So maybe GM David Stearns is looking to ease that bottleneck.

The other approach would be to move one or more of those aforementioned prospects in order to improve the 2018 roster. After all, the resurgent Brewers won 86 games a season ago and finished only one game out of playoff position.
