Let's carry this thought forward. Oakland has three choices here: (1) Pull him back from waivers. (2) Just let him go to the Cubs - Cubs would assume the remaining contract. (3) Make a trade. If I understand waivers correctly with item 3, the Cubs can only trade 3 types of players: (a) player(s) from the Cubs 40-man who has (have) cleared waivers; (b) a player from the Cubs 40-man, who was claimed on waivers first by Oakland; © player(s) who is (are) not on the 40 man roster. If it's scenario 3a or 3b, there would be no impact on the 40-man roster; however, if it's scenario 2 or 3c, the Cubs would have to remove somebody from their 40 man roster to add Stewart. That would be either a player who has cleared waivers or somebody the Cubs would have to DFA. Interested to see how all this unfolds. I guarantee ohman is in this deal. his cubs career is over.
