This blog recently profiled the knuckleball brothers when Joe appeared in the 1978 Burger King Astros. Coincidentally, he and Phil both went 7-13 in 1987 and split the year between multiple teams. Phil made 22 starts with Cleveland prior to short stints with Toronto and Atlanta. Joe began the year in pinstripes, but finished with the champion Minnesota Twins and threw 2 innings in game 4 of the World Series.
Phil retired (at age 48!) after 1987 and Joe pitched part of 1988 for the Twins before hanging them up. He collected the last of their 539 victories on April 12th by pitching 2 scoreless relief innings in a 7-6 result over Cleveland.
