Felske batted and threw right-handed, stood tall and weighed. After attending the University of Illinois, Felske signed with the Chicago Cubs in 1961, but his shortcomings as a batter—and the durability of Chicago backstop Randy Hundley—kept him at the minor league level except for two at bats in the middle of the season. He was drafted by the Seattle Pilots in December 1969, and played a total of 50 games over the and seasons for the Pilots' successor franchise, the Milwaukee Brewers, as third-string receiver. Overall, Felske, a right-handed hitter, batted only.135 in his major league career with 14 hits and one home run, hit onJune 1, 1972, against Lindy McDaniel in a 9–8 Brewer win over the New York Yankees at Milwaukee County Stadium.
Manager and coach
In, Felske turned his hand to managing in the Brewer farm system, reaching the Triple-A level in. After winning the division title with the Vancouver Canadians of the Pacific Coast League, Felske was named as the bullpen coach for the Toronto Blue Jays under skipper Bobby Mattick for and. When Mattick stepped down in favor of Bobby Cox, Felske joined the Philadelphia farm system, and won another PCL divisional title in with the Portland Beavers. He was promoted to the Phillies' coaching staff for the 1984 season as heir apparent to their skipper Paul Owens, who also was the club's general manager. Owens resigned his managing post September 30 of that season, and Felske took over the helm. However, the Phillies—1983 National League champions—were in rapid decline. Hall of Fame left-hander Steve Carlton was coming to the end of his career, and youngsters called up to replace aging veterans fell short of expectations. The 1985 Phillies won only 75 games, and Felske bore the brunt of criticism from fans and media. While the 1986 club improved to second place in the NL East Division and 86 wins, it finished 21½ games behind the frontrunning rival and eventual championNew York Mets. Meanwhile, the team's front officeturned over with Owens' retirement. In 1987, when the Phillies won only 29 of their first 61 games on their way to a fourth-place finish, Felske was fired June 18.
