Mather, who was selected by the Cardinals in the third round of the 2001 First-Year Player Draft, spent parts of 10 years in the organization before he was selected off waivers by the Braves after the 2010 season. He began Monday hitting .263 with two home runs and six RBIs, and he had appeared in 20 games, starting eight. That included a walk-off single against the Cardinals on April 23 at Wrigley Field.
"They've given me a real good opportunity here," Mather said. "I can't complain."
Mather began the 2010 season on the Cardinals' Opening Day roster but was optioned to Triple-A Memphis seven weeks into the season. He spent the final two weeks of the regular campaign with St. Louis. Atlanta claimed him that November, then let him go last June.
Chicago signed Mather to a Minor League deal in December. His can play a variety of infield and outfield positions, and that endeared him to the organization.
"They run me out there every few days and that's all that I can ask for," he said. "They've treated me well."
