Zack Greinke tossed six quality innings in yesterday's 8-4 win over the Reds, but he gave some Brewer fans a scare when he was pinch hit for in the top of the 7th. This had everything to do with there being runners on second and third with no one out and nothing to do with a potential trade, but the amount of scouts in the crowd today was mentioned several times on the broadcast and despite the game situation, Brian Anderson even went so far as to mention that his exit "makes you wonder".Nevertheless, it seems we have reached the point where a Greinke trade is worth confronting with the non-waiver trade deadline just over a month away. While the season is not lost yet, the wagons are beginning to circle, as noted by FOX Sports' Jon Paul Morosi in his column last night. He notes three teams who had scouts at yesterday's game: the Rangers, Angels, and Yankees. Assuming Greinke is not offered an extension to his liking (got Matt Cain money sitting around?), rival execs believe that the Brewers will try to trade him, according to FOX Sports' Ken Rosenthal. Here are the clubs that might become involved, including what the Brewers may seek in return.
