Shelby Charles Miller (born October 10, 1990) is an American professional baseball pitcher in the Arizona Diamondbacks organization.

He has previously played in Major League Baseball (MLB) for the St. Louis Cardinals, Atlanta Braves, Texas Rangers, Chicago Cubs, Pittsburgh Pirates, San Francisco Giants, Los Angeles Dodgers and Detroit Tigers.

A fourth award, MLB.com's Pitching Performance of the Month, was the result of his first MLB complete game shutout in May 2013, a one-hitter against the Colorado Rockies.

[3] He played quarterback until the seventh grade, when he suffered a staph infection, allowing Casey Pachall to win the role.

At the time of his promotion, he led the FSL with 81 strikeouts, and was considered the best pitching prospect in baseball by Keith Law of ESPN.com.

[19] After the season, Baseball America rated his fastball as the best in the Cardinals system, and named him a starting pitcher on their 2011 Minor League All-Star team.

[8] After competing for a spot on the Cardinals roster, he began the 2012 season with the Memphis Redbirds of the Triple–A Pacific Coast League (PCL).

[23] Amidst the Cardinals' competition for a playoff spot, Miller recorded his first major league win as a reliever in an extra inning game against the Los Angeles Dodgers on September 16.

He appeared twice in relief for the Cardinals during the 2012 National League Championship Series (NLCS) against the San Francisco Giants, allowing four hits and two runs in 3+1⁄3 innings.

He walked none, striking out a career-high 13, which tied the Cardinals' rookie record, also held by Dick Hughes and Scipio Spinks.

On the second pitch of the game, a line drive off Carl Crawford's bat glanced struck Miller's right elbow.

[34] On September 11, Miller continued his dominance over the Milwaukee Brewers, allowing five hits and striking out four in 6+2⁄3 innings.

[37] As teammate Adam Wainwright defeated the Chicago Cubs in his final start of the season on September 28, 2013, he tied Zimmermann for the league lead in wins.

[26] Although Miller was on the roster for all three series in the Cardinals' 2013 postseason run, manager Mike Matheny did not place him in the starting rotation.

Instead, he totaled a single inning in one relief appearance against the Pittsburgh Pirates in the 2013 National League Division Series (NLDS), in which he gave up one home run.

"[40] After losing the World Series in six games to the Boston Red Sox, Matheny and general manager John Mozeliak explained that Miller's role was as "insurance."

He took a no-hitter into the sixth inning, faced 30 total batters while striking out five and enjoyed much more consistent command.

[48] On November 17, 2014, the Cardinals traded Miller and prospect Tyrell Jenkins to the Atlanta Braves for outfielder Jason Heyward and relief pitcher Jordan Walden.

The two-hitter against the Marlins would serve as Miller's last win until his final start of the season, on October 4, when he pitched eight innings in a shutout effort against the St. Louis Cardinals.

[58] On December 9, 2015, the Braves traded Miller and Gabe Speier to the Arizona Diamondbacks in exchange for Dansby Swanson, Ender Inciarte, and Aaron Blair.

[61] He struggled once the season began,[62] and was placed on the disabled list on May 24 due to a sprained index finger, making his return on June 20.

[63] Miller pitched to a 2–9 record and a 7.14 ERA through the MLB All-Star break, when the Diamondbacks optioned him to the Reno Aces of the PCL.

In 8 starts split between the rookie–level Arizona League Brewers and Triple–A San Antonio Missions, he compiled a 1–3 record and 4.13 ERA with 36 strikeouts across 32+2⁄3 innings pitched.

[81] After making three appearances in which he surrendered seven earned runs and recorded six outs, he was placed on the 10-day injured list with a lower back strain.

[82] That night, Miller pitched the first three innings of a no-hitter against the Indianapolis Indians at Principal Park in Des Moines, Iowa.

[83] He struck out five batters and walked one before being relieved by Tommy Nance, Brad Wieck, and Ryan Meisinger who completed the combined no-hit game.

[88] On March 27, 2022, the New York Yankees signed Miller to a minor-league deal with an invite to the team's major-league spring training camp.

[93] On September 29, Miller became the first pitcher in the modern era to have back–to–back outings with five or more strikeouts in less than three innings with no walks or runs allowed.

Miller was designated for assignment by the Tigers on September 24, 2024, in order to make room for their young star pitching prospect, Jackson Jobe.

Miller is married to Michigan native Erika Romans, who played volleyball at Milford High School.
