“One reason the situation isn’t so easy is that not only does Martinez have two potential teams at the moment, he also has appears to have multiple people laying claim to the role of his agent — one sanctioned player agent and multiple buscones, or street agents. It also isn’t quite clear at the moment how many buscones he actually has.
It all started when Martinez or a representative of his reached an agreement reported to be for $2.5 million with the Giants. But that was just the beginning. While the Giants apparently were under the impression their agreement was binding, Martinez or another representative some time after that made a deal with the Cubs, reportedly for $3 million.”
