“Miller’s changeup was so good because his motion was so hard to figure out,” Mudcat Grant said.
Originally a starting pitcher, Miller didn’t throw very hard and had troubles early in his career. In his first five seasons, mostly as a starter, he had a 4.27 ERA and bounced around to three different teams. Finally, with the Giants in the late 1950s, Miller learned to master his changeup, using a fastball-like motion on a pitch that went to home plate at speeds no higher than 84-84 MPH. Under Billy Rigney after the Giants moved to San Francisco, Miller was utilized as a relief ace, entering games in the 7th, 8th, or 9th innings to hold a lead or keep the game close. He twice led the league in saves in the 1960s, doing it once in each league.
