Rule 5 deadline has already passed. For sure it's deceptive to look at it as some kind of heist for the White Sox but Bummer has been good 3 or 4 seasons out of the last five and is controlled for another three so that's a lot of value. Like trading for Alvarado, basically (and more valuable than Soto who is both not as good and much closer to free agency). Obviously the Braves liked his FIP and viewed this year as an outlier or unlucky.
