Duffy attended Cabrillo High School in Lompoc, California, where he pitched for the school's baseball team. As a senior, Duffy had a 5–3 win–loss record, a 0.60 earned run average (ERA), and 127 strikeouts in 58 2⁄3 innings pitched.
The Kansas City Royals drafted Duffy in the third round of the 2007 Major League Baseball Draft. He began his professional career that season with the Arizona Royals of the Rookie-level Arizona League, where he pitched in 11 games and had a 1.45 ERA.
The Royals promoted Duffy to Burlington Bees of the Class-A Midwest League in 2008, where he had an 8–4 record and a 2.20 ERA in 17 starts. He was named Burlington's Pitcher of the Year. In 2009, Duffy started 24 games for the Wilmington Blue Rocks of the Class-A Advanced Carolina League. He was named a Carolina League All-Star, and finished the season with a 9–3 record and a 2.98 ERA. Duffy represented the Royals in the 2009 All-Star Futures Game, where he pitched 2⁄3 scoreless innings.
The Royals invited Duffy to spring training in 2010. However, Duffy abruptly retired from baseball in March 2010, at the age of 21. He informed J. J. Picollo, the Royals' assistant general manager of scouting and player development, that he wanted to "reassess his life priorities". The move reminded many of Zack Greinke's departure from the Royals' camp in 2006. Realizing that he missed the game of baseball, Duffy decided to return to the Royals in June, and showed up at the extended spring training in Surprise, Arizona. Later that season, Duffy pitched for Wilmington, the Idaho Falls Chukars of the Rookie-level Pioneer League, and Northwest Arkansas Naturals of the Class-AA Texas League. Duffy went 5–2 with a 2.95 ERA in seven regular-season starts for the Naturals, and 1–0 with a 1.69 ERA in two playoff games, as the Naturals won the Texas League championship. He pitched in the Arizona Fall League after the season.
Heading into the 2011 season, Baseball America rated Duffy the 68th best prospect in baseball. The Royals again invited Duffy to spring training. Duffy began the 2011 season with the Omaha Storm Chasers of the Class-AAA Pacific Coast League (PCL). With Omaha, Duffy was named PCL Pitcher of the Week for the week of April 25 – May 1. Duffy pitched to a 3–1 record and 3.00 ERA in seven starts for Omaha, recording 43 strikeouts while only walking 10 and allowing 30 hits in 36 innings. The Royals promoted Duffy to Major League Baseball (MLB), and he made his MLB debut on May 18, 2011. He gave up two runs in four innings; he did not earn a decision in the 5–4 loss to Texas. He recorded his first MLB win on June 14, going six innings in a win over the Oakland Athletics. Duffy finished the 2011 season with a 4–8 record and 5.64 ERA in 20 MLB starts.
Duffy made six starts in 2012 before suffering a torn UCL in his left elbow that required Tommy John surgery on June 13, 2012. Prior to being sidelined, Duffy had a 2-2 record with an ERA of 3.90. On November 2, 2012, the Royals reinstated Duffy from the 60-day disabled list; however, he was not expected to return to pitching for the Royals until late June or early July.
On May 26, 2013, Duffy began a rehab assignment with the Double-A Northwest Arkansas Naturals. On June 6, the rehab assignment was changed to the Triple-A Omaha Storm Chasers. He was optioned to Omaha at the end of the rehab period on June 25. Duffy was recalled from Omaha on August 7, and returned on August 8. He was recalled on August 16 to start game 1 of a doubleheader against the Detroit Tigers.
During spring training in 2014, Yordano Ventura won the final spot in the Royals' starting rotation over Duffy. However, when Bruce Chen went down with a back injury early in the season, Duffy took over his spot in the rotation.
