Yovani Gallardo's name has been mentioned in trade rumors recently, but there will be roadblocks for some clubs.

Gallardo can block a trade to the Orioles, Red Sox, Indians, Tigers, Astros, Angels, Yankees, Phillies, Pirates and Blue Jays.

Gallardo is 6-7 with a 4.20 ERA on the season and is already receiving "some" trade interest.
