Since 1992, he hosted the seasonal Chicagoland Golf Show, a talk radio program on CBS Radio-owned WSCR SportsRadio 670 in Chicago.
Kosin began covering sports at his high school at age 14 for the City News Bureau of Chicago and two competing local newspapers, getting bylines in each and earning himself the princely sum of $32.50 a week.
He worked full-time in the production department on the third shift at a Chicago daily newspaper while attending junior college, then majored in broadcasting and journalism at Western Illinois University.
From 1980 through 1988, Kosin reported on all Chicago sports and teams while hosting weeknight “magazine” shows on two radio stations, WTAQ and WMRO.
At that time Kosin also wrote syndicated semi-weekly newspaper columns, in addition to stringing for The Associated Press at major sporting events.
Kosin covered 32 straight Westerns (until its contentious demise in 2006) and more than 500 golf tournaments, including nearly 60 major championships.
After freelancing for several marginally successful regional golf publications for many years, Kosin became editor of Illinois Golfer in 1986.
Since 1994, his "Phil Kosin's Chicagoland Golf Show" was on the air on powerful stations in the nation’s third-largest media market.
After three years on WMVP-AM1000 (now ESPN Radio), for the last 13 seasons, he hosted a Saturday morning, two-hour weekend show from March through September on WSCR TheScore, SportsRadio 670AM in Chicago, in addition to being streamed live on the Internet at www.670thescore.com.
