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. Are we assuming the Cubs are the highest priority team to put in a claim? From what I heard they were. The ESPN 1000 broadcast said that the Cubs put claims on 3 other players but were denyed by higher waiver teams. Stewart, however, fell to the Cubs and is available to be traded.
