The Florida Marlins announced today they have acquired left-handed pitcher Oswaldo Mairena from the Chicago Cubs for Manny Aybar. Mairena, 25, spent time with the Cubs and Yankees last season. Chicago acquired him on July 21, 2000 from New York along with pitcher Ben Ford for outfielder Glenallen Hill. He made his Major League debut on September 5 at Colorado. Mariena had a combined 2-6 record with a 3.26 ERA in 53 minor league games last season. He spent time with AAA Columbus, AA Norwich, AA West Tennessee and AAA Iowa last year. Mairena has appeared in two Major League games, both with Chicago, and has allowed four earned runs in two innings pitched.
