[1][2] Gibson played briefly for the Falmouth All-Stars of the Cape Cod Baseball League in 1957, just prior to being signed by the Red Sox.

[8] Rohr was one strike away from a no-hitter when Yankees' catcher Elston Howard looped a two-out, ninth inning single to right-center field.

In early May, Gibson was optioned to the Pittsfield Red Sox of the Eastern League (then at the Double-A level);[10] he was recalled to Boston later in the month.

[11] On June 12, Gibson hit a two-run home run at Fenway Park off of Joe Verbanic to help defeat the Yankees, 3–1;[12] it was his first major league homer.

A member of the pennant-winning 1967 Red Sox "Impossible Dream" team, Gibson caught the first game of that year's World Series against the St. Louis Cardinals; he was 0-for-2 before being lifted for a pinch hitter in the seventh inning.

Gibson had resided in Swansea, Massachusetts, since 1982, and died there at age 69 after a long illness,[18][19] on the same day that his 1967 Red Sox manager, Dick Williams, was inducted into the Baseball Hall of Fame.
