The brother of Hall of Famer George Brett, Ken Brett pitched fourteen years in the majors, and was an All-Star in 1974 with the Pittsburgh Pirates. After his playing career ended, he was a broadcaster for the Seattle Mariners and California Angels. He died of cancer in 2003.
As an 18-year-old rookie in 1967, he appeared twice in the 1967 World Series for the Boston Red Sox.
When his brother George broke in during the 1973 season, Ken was already in his sixth major league season, one in which he went 13-9. He pitched with 10 teams in his career, getting 83 wins.
During the years 1973-96, when AL pitchers rarely batted, Brett's total of 12 at-bats (for the 1976 White Sox) was easily the single-season record. No other pitcher had more than 3 ABs in a season.
For a pitcher of his era, he was a remarkably good hitter. He had a lifetime batting average of .262, and slugged .406. With the 1973 Phillies, he drove in 16 runs with a .462 slugging percentage. During the '73 season, he homered in four consecutive games. With the 1974 Pirates, he hit .310 and drove in 15 runs with a .448 slugging percentage. In both years, the National League average slugging percentage was around .370.
Faced his brother, George, 20 times in his career, giving up 6 hits, 2 doubles and 1 RBI.
Along with brothers George, Bobby and J.B., Ken bought the Spokane Indians in 1985. They have also purchased the Spokane Chiefs minor league hockey team, the Tri-City Dust Devils, and the High Desert Mavericks.
