[8] On April 30, 1967, Barber was removed from a game against the Detroit Tigers with two outs in the ninth inning despite having not surrendered a hit.

He had walked two men to start the inning, and then had two outs with runners at second and third when he threw a wild pitch, allowing the tying run to score.

He then walked another batter, his tenth of the day (to go along with two hit batsmen and two wild pitches), and manager Hank Bauer took him out of the game, even though he still had the opportunity for a no hitter.

Later that year, on December 15, the Yankees sent minor-leaguers Chet Trail and Daniel Brady to the Orioles to complete the trade.

[4] Barber was selected by the Seattle Pilots in the 1968 Major League Baseball expansion draft when the Yankees left him unprotected.

[4] He was released just before the 1970 season, but played that year for the Chicago Cubs, and then for the Atlanta Braves, pitching almost exclusively in relief.

[14] Barber was involved in a nine-player transaction when he was sent along with Clyde Wright, Ken Berry, Art Kusnyer and cash from the Angels to the Milwaukee Brewers for Ellie Rodríguez, Ollie Brown, Joe Lahoud, Skip Lockwood and Gary Ryerson on October 23, 1973.

[15] After being released by the Brewers during spring training, he later appeared in 13 games for the San Francisco Giants in the middle of the 1974 season.

[14] In 466 MLB games pitched, including 272 as a starter, Barber posted a 121–106 won–lost mark and a 3.36 earned run average.
