According to this article, the team could still offer him arbitration. I thought because it was a vesting option, they couldn't but I was ignoring the fact that it also had a buyout, meaning there was a team option as well. "According to a recent posting of MLBTR’s updated Elias Rankings, K-Rod has joined Carlos Beltran and Jose Reyes as the Mets only Type-A free agents. That means if a team offers him arbitration at the end of this year(assuming his vesting option doesn’t kick in) and K-Rod turns it down and signs elsewhere, the team signing him forfeits their first round selection in the 2012 First Year Player Draft as well as a supplemental pick between rounds 1 and 2. If the team signing K-Rod has a pick in the top 15, they then forfeit their 2nd round selection(or another later pick depending on if that team signs more than one Type-A free agent, which is decided by the players ranking under the Elias system). What all that in the last paragraph means is that Rodriguez could have added value to another team should he get traded. If he is traded to another team where he would set up, he is less likely to finish off 55 games. That would prevent his option from picking up and make him a free agent at the end of this season. A guy like Frankie Rodriguez solidifying the 8th inning while also having the potential to bring in 2 high end draft picks could be really enticing to a contender. It could also help the Mets get a good piece in exchange for their closer while also shedding some unwanted future salary." Edit: assuming this is true, would the Brewers offer him arbitration? I think they would but there would always be a chance he accepts and still gets something like 15 mil.
