[1] Miller played for ten teams during his major league career, tying a modern-day record (since 1900) with Dick Littlefield that has since been broken.

In the 1956 American Legion Baseball championships, Miller won all three games for the St. Louis Stockhams to lead the team to the national title.

[8] Miller pitched in four more games in the 1957 season, seeing a total of nine innings of work, all in relief, ending with an earned run average (ERA) of 7.00.

[10] In the 1961 MLB Expansion Draft held on October 10, 1961, the New York Mets picked Miller as one of three players they selected from the Cardinals, joining catcher Chris Cannizzaro and outfielder Jim Hickman.

[1][12] Miller was the starting pitcher on the losing end of a no-hitter pitched by Sandy Koufax of the Dodgers on June 30, 1962, a 5–0 Mets loss.

[14] In losing his first 12 decisions with the Mets, Miller tied a then-Major League record for losses by a pitcher at the start of the season.

[1] Miller faced off against Jim Palmer, but lasted only 1+2⁄3 innings, giving up five hits and three runs (only one of them earned) before being removed by manager Billy Martin.

[26][27] Miller's journeyman travels started when he was traded by the Twins to the Cleveland Indians on December 10, 1969, together with Dean Chance, Graig Nettles and Ted Uhlaender, in exchange for Luis Tiant and Stan Williams.

[4] He was dealt along with Barry Moore from the Indians to the White Sox for Buddy Bradford and Tommie Sisk before the trade deadline on June 15, 1970.

[4] On September 1, 1970, he was purchased by the crosstown Chicago Cubs from the White Sox for an amount described by The Washington Post as being well above the $20,000 waivers price.

[32] Miller continued his success in the bullpen, ending the season with the Pirates with a 1–2 record and three saves in 16 appearances, all in relief, finishing with a 1.29 ERA.

[37] Miller was released by the Pittsburgh Pirates on March 27, 1973, and signed as a free agent with the San Diego Padres on April 2, 1973.

[4][38] The Mets made it to the 1973 World Series, losing to the Oakland Athletics in seven games, but Miller was not placed on the postseason roster, as he had joined the team too late in the season.

His final appearance was on September 28, 1974, in a 7–3 loss to the Pirates, with Miller getting the last two outs of the fifth inning in relief of starter Tug McGraw.

[4] In 1976, Miller was named as manager of the Amarillo Gold Sox, the double-A Texas League affiliate of the San Diego Padres.

He led the team to a first-place finish with an 81–54 record, and won the league championship over the Shreveport Captains, a Pittsburgh Pirates affiliate, winning the best-of-five series in five games.

[5] Miller spent three seasons with Toronto, helping to develop future stars Dave Stieb and Pete Vuckovich.

[41] Miller, then an advance scout for the Giants, died of injuries sustained in a collision with another vehicle in Rancho Bernardo, California, near San Diego.
