The Nationals haven't made a formal proposal, Kilgore writes, but the team is looking into what it would take to acquire the starter as it tries to bolster a starting rotation that remains questionable beyond its top three starters: Stephen Strasburg, Gio Gonzalez and Jordan Zimmermann.
Garza, 29, will be a free agent for the first time after this season. Any team that trades for him would not receive a compensatory draft pick if Garza were to sign elsewhere after the season, according to baseball's current collective bargaining agreement.
Garza didn't make his 2013 debut until May 21 with a latissimus dorsi strain in his shoulder. He's allowed a run or fewer in his last four starts and has pitched at least seven innings in each of those appearances. With Ricky Nolasco now a member of the Los Angeles Dodgers following Saturday's trade with the Miami Marlins, Garza is considered one of the top starting pitchers remaining on the trade market.
