According to a report by Jayson Stark (subscription required), the Mets are among several teams taking a good hard look at free-agent journeyman starter Rodrigo Lopez, most recently of the Diamondbacks. Lopez had Tommy John surgery (surprise!) in August of 2007 and pitched just five minor league innings in 2008. In 2009 he split time between the Phillies and their Triple-A club, tossing 130 innings in all and generally wowing nobody. He threw 200 innings with the Diamondbacks last year with a 5.00 ERA, 5.21 FIP, and 4.70 xFIP.
Lopez figures to be a below-average pitcher even with Citi Field as his home park, but there's little to lose here on a minor league deal with an invitation to spring training. He probably isn't a better option than Dillon Gee or even Pat Misch, but I assume Sandy Alderson wouldn't even consider a major league deal for Lopez.
