Free agent right-hander Ervin Santana is drawing interest from eight teams including the Rockies, Orioles, Mariners, Yankees and Dodgers, according to a source with direct knowledge of the situation. The Marlins and Cubs also recently inquired about him, but their interest does not appear to be too serious at this time. With Masahiro Tanaka and Matt Garza recently off the board, Santana's market is expected to heat up in the near future, with league sources speculating that teams like the Blue Jays, Diamondbacks, Royals and Tigers could become involved. Things have been quiet on the Santana front since Thursday, and sources caution that it is "still early" in the process.
