A Cub from San Francisco

I am listening to the SAN FRANCISCO GIANTS on the radio while reading about the memorable debut of a CHICAGO CUB.
ROB SPERRING was actually born in San Francisco on Oct. 10, 1949.
He grew up in LODI, CALIF., playing high school baseball for the Lodi Flames and in college for the UNIVERSITY OF THE PACIFIC.
The Cubs selected Sperring in the fifth round of the 1971 amateur entry draft.
Ironically, he made his Major-League debut on Aug. 11, 1974 against the Giants.
It was one of his best games, unfortunately.
Sperring doubled and homered, but the Giants beat the Cubs, 5-3, in a game that featured a stolen base (of all things) by San Francisco's DAVE KINGMAN.
Sperring played sparingly for the Cubs. He was traded before the start of spring training in 1977 -- the Giants, with Bill Madlock in exchange for Bobby Murcer, Steve Ontiveros and Andy Muhlstock.
Sperring never appeared for the team from his birthplace -- the Giants shipped him to Houston on March 26, 1977 -- and he closed out his big-league career with 58 games with the Astros that season.
What ever became of Rob Sperring?
Well, I know he and his family live in Cypress, Texas and that his son, Trey Sperring, plays college ball at Oklahoma.
