Adam Kilgore of the Washington Post has it:
The Nationals have kicked the tires on Cubs right-hander Matt Garza, one person familiar with the situation said. Talks between the teams have not progressed to the point of the Nationals offering the Cubs a formal proposal.
Garza is also thought to be drawing trade interest from the Orioles, Rangers, Red Sox, Blue Jays, Indians and Dodgers, so he is not going to be an easy (or inexpensive) get for the team that ultimately acquires him.
Eduardo Encina of the Baltimore Sun reported Saturday that the Cubs wanted two of the Orioles’ top five prospects — infielder Jonathan Schoop and left-hander Eduardo Rodriguez — in exchange for Garza.
Garza has an excellent 3.45 ERA, 1.12 WHIP and 52/18 K/BB ratio through his first 57 1/3 innings this season with Chicago. The 29-year-old is scheduled to hit the free agent market in November.
