A seventh-round pick out of North Carolina-Charlotte in 2014, the 23-year-old Butler reached Double-A San Antonio the season after being drafted. Now he's making another statement in the Arizona Fall League.
After three appearances, including one start, Butler is 2-0 with a 1.50 ERA. He has allowed one run on four hits and three walks with two strikeouts in six innings.
"He looked aggressive, and the ball was coming out really well," said Sam Geaney, the Padres' director of player development, after seeing Butler's start in the AFL.
Butler opened last season with Class A Advanced Lake Elsinore and was 3-2 with a 3.66 ERA in 12 appearances, including seven starts. He was 0-3 with a 4.78 ERA in three starts with Double-A San Antonio. However, the shoulder fatigue limited Butler to just 64 2/3 innings.
At the moment, the Padres are still discussing whether the 6-foot-4, 225-pound Butler projects better as a starter or a reliever. Also undetermined is where Butler might start the 2016 season.
Butler is not the only prospect pitching well for the Peoria Javelinas in Arizona.

Yardley was a California League All-Star and Lake Elsinore's Pitcher of the Year last season. He was 2-4 with a 2.72 ERA and 16 saves in 20 chances with the Storm in 2015. He appeared in 47 games with Lake Elsinore and made five appearances (0-1, 5.14 ERA) with San Antonio.
