Dude could bring it. Pre-Statcast, pre-ESPN highlights, pre-radar guns, I don't care if you think the average pitcher was lobbing it underhanded back then. Vida Blue threw gas. He'd get that right leg cocked up well over his waistline and let loose, daring hitters to try and catch up with the heater.
He had a good curveball, which he used just enough to keep guys from getting locked in, but the fastball was his bread and butter. Man, the sound it made when it hit the catcher's glove was unique -- even if there weren't a whole lot of fans around to hear it.
His 1971 season was spectacular and the attention he received in the Bay Area and nationwide was similar to that of Fidrych and Valenzula later on. Then he got in a contract dispute with Charlie Finley in the off-season and missed most of 1972, but the A's were so good that they could start Hunter, Odom and Holtzman in the American League Championship Series and then give the ball to Vida to close out Game 5 with four innings of relief, just mowing down the Tigers.
He then went on to win 77 games over the next four seasons, and when Finley couldn't dump him on the Yankees or Reds because of Bowie Kuhn, he got stuck as the only good player on a roster of AAA players in 1977.
By the time he finished his first stint with the Giants, his off-field troubles pretty much ended his career.
Getting to see Blue in his prime was special. RIP, Vida.
