A third-round pick of the San Francisco Giants out of high school in 2015, Miller made a name for himself in the minors, reaching Double-A with both the Giants and his hometown Atlanta Braves. The 28-year-old was a California League Mid-Season and Post-Season All-Star with the San Jose Giants in 2018 and was an Eastern League Mid-Season All-Star with the Richmond Flying Squirrels in 2019. Miller spent his first five seasons in the Giants organization before playing two years at Double-A Mississippi with the Braves, having been selected in the Rule 5 draft by Atlanta. 

Miller first came to York in 2023, but after a slow start, was released to make room for incoming big league veteran Richard Urena when the Revs were needing another left-handed bat and subsequently signed with Charleston. Afforded the opportunity to play every day, the right-hand hitting Miller batted .279 with 12 homers in 90 games for the Dirty Birds and finished fourth in the Atlantic League with 32 doubles and 10th in the league with 32 steals. Last season, Miller returned in July from a hand injury and batted .271 with five homers, eight doubles, 17 RBI, and 13 steals in 38 games for Washington in the Frontier League.

Miller made minor league history on April 11, 2018 in a road game against the Lancaster Jethawks when he homered in the eighth inning and tripled in the ninth, joining teammate Gio Brusa as the duo both hit for the cycle in the same game, the official scorecard of which is now in Cooperstown.  Miller is a career .238 hitter with 70 homers, 178 doubles, 19 triples, and 131 stolen bases in 846 games across nine pro seasons.
