CHICAGO -- The Chicago Cubs made their final roster official not long before game time Thursday with the biggest news being that they lost a highly regarded left-handed pitcher in the process.
In an effort to clear spots on the 40-man roster, the Cubs ended up seeing left-hander John Gaub get claimed off waivers by the Tampa Bay Rays. Another spot was cleared on the 40-man by putting right-hander Marcos Mateo on the 60-day disabled list with ulnar neuritis.
The Cubs did not announce anything with Rodrigo Lopez, who did not make the Opening Day roster. Lopez is expected to be placed on the roster over the weekend. To make room for the long man a position player figures to be on the way out.
