[4] Bradley became Seattle's regular left fielder in 1984, batting .301 with 24 RBI in 124 games, but did not show any power, hitting no home runs.
[8] Bradley was dealt along with Tim Fortugno from the Mariners to the Philadelphia Phillies for Glenn Wilson, Mike Jackson and Dave Brundage at the Winter Meetings on December 9, 1987.
[10] Bradley was acquired by the Baltimore Orioles for Ken Howell and Gordon Dillard on December 9, 1988, exactly one year to the day of his trade to Philadelphia.
"[12] After batting .270 (78-for-289) with four home runs, 26 RBI and 10 stolen bases through the first four months of the 1990 season,[13] Bradley was traded from the Orioles to the Chicago White Sox for Ron Kittle on July 30.
[15] He had rejected the Orioles' one-year $1.3 million contract offer which he called "a humiliation" a week prior to the trade.
[14] Baltimore general manager Roland Hemond was criticized by the Daily Press for bringing on too many ex-White Sox like Kittle, Greg Walker, Kevin Hickey, Tim Hulett and Dave Gallagher.
[15] Bradley's final major league appearance came on September 29, 1990, as he drew two walks and scored a run in a 5–2 White Sox win over the Seattle Mariners.
In September 2009, Bradley was named as a volunteer assistant coach of the University of Missouri softball team for the 2009-10 season.
