Early career
Born in Long Beach, California, Duffy attended Lakewood High School in Lakewood, California, where he acquired the nickname "Duffman." At Lakewood High School, Duffy was a two-year letterwinner and led the team to a 23-12 record and a league championship in 2008. He was a two time all-state selection and a two-time all-league pick also. As a junior, Duffy achieved a batting average of .409 and 28 runs batted in. He hit .380 his senior year with 34 runs batted in and 3 home runs.
Duffy played college baseball at Long Beach State University from 2010 to 2012. During his 2010 season at Long Beach State, Duffy played in 30 games, starting 20 of them, averaged .244, had 86 at bats, 8 runs, 21 hits, and 7 RBI. In the 2011 season, Duffy played in 55 games, started 54 of them, averaged .266, had 214 at bats, 22 runs, 57 hits, and 31 RBI. In those two seasons at Long Beach State, Duffy played in 85 games, started 74 of them, averaged .260, had 300 at bats, 30 runs, 78 hits, and 38 RBI. In 501 college at bats, Matt Duffy hit .253 and had an on-base percentage of .305. Over those three seasons, Duffy recorded zero home runs, sixteen doubles, and one triple. He was kept on the team because of his defensive abilities.
Between his sophomore and junior seasons, Duffy played in the Cape Cod League, where he improved his swing by standing further back in the batter's box and incorporating a leg kick. His coach urged him to read Harvey Dorfman's "The Mental Keys to Hitting", which Duffy says he has read at least 10 times and refers back to whenever he is in a slump.

Major league career
2014
Duffy was called up to the San Francisco Giants and played his first game in the major leagues on August 1, 2014. In the 2014 regular season, Duffy played in 34 games and had 60 at bats. He recorded 16 hits and 5 runs with a batting average of .267 and on-base percentage of .302.

In the 2014 World Series, at age 23, he was the youngest player on the Giants' 25-man roster. By this point in his career, the knobs of his bats were decorated by cartoon "Duffman" decals.
2015
Duffy was invited to his first Spring training in 2015, where he hit .361 and earned the Barney Nugent Award, given to the player in his first Major League camp whose performance best exemplifies the spirit of the club. On April 5, 2015, Duffy was named to the Giants' opening day 25-man roster. He hit his first major league home run on April 15, 2015, against the Colorado Rockies. On May 10, 2015, Duffy hit a walk-off, bases-loaded single in the bottom of the ninth inning to defeat the Miami Marlins 3-2.

Duffy was the first Giants rookie to collect 5 RBIs in a game since Buster Posey on July 7, 2010.
As a utility infielder, Duffy played all four infield positions during April and May, but he primarily played at third base as regular starter Casey McGehee struggled. On May 24, 2015, Duffy was awarded the starting third base job for the Giants after McGehee was designated for assignment. In June, Duffy batted .313 with 6 doubles, 3 triples, 5 home runs, and 15 RBIs, eventually working his way up to third in the batting order.

The next night, Duffy hit a two-run, go-ahead triple in the sixth inning as the Giants came from behind to defeat the Phillies 8-5.

On August 14, Duffy hit his tenth home run of the season off Max Scherzer of the Washington Nationals, finishing 3-for-3 with a single, double, and home run, falling one hit short of the cycle for the fourth time.
On October 2, Duffy won the 2015 Willie Mac Award for the team's most inspirational player, the first rookie to win in the award's 35-year history. Duffy finished his first full major league season batting .295 with 12 home runs, 6 triples, 28 doubles, 169 hits, and 77 runs scored.
