Matt Duffy

On January 30, 2020, Duffy signed a minor league deal with the Texas Rangers.

Duffy endured another injury shortened season in 2019, playing only in 46 games for the Rays. Duffy was designated for assignment on November 20, 2019 and released on November 22.

Following a successful offseason, Duffy made the Rays 2018 opening day roster and became the first Ray to play third base since the trade of Evan Longoria. On April 17, Duffy was placed on the 10-day disabled list due to a right hamstring strain, he returned shortly after. On June 13, Duffy hit a walkoff single against the Toronto Blue Jays in a 1–0 victory. On September 20, Duffy possessed a .300 batting average and had a chance to become the first Ray to finish the season with a .300 average since 2011. Following a 1-13 skid, Duffy ended his first full season since 2015 slashing .294/.361/.366 with four home runs in 132 games and was considered a front runner for the comeback player of the year award. He had the lowest ISO (Isolated Power) of all MLB players in 2018, at .072.

The original plan for the 2017 season was for Duffy to start the season at shortstop, assuming his Achilles would heal at the expected rate. But due to complications in the rehabilitation process, Duffy was placed on the 60-Day DL. Duffy came as close as a rehab stint to playing again in 2017, but more complications arose, drawing more setbacks. Duffy and the Rays organization expressed their frustrations with the rehabilitation process but still remained optimistic that he would appear in the 2017 season. Complications continued, however, and Duffy never made any appearance in a game in 2017. At the conclusion of the 2017 season, Duffy joined the instructional and winter league Rays' affiliates with hopes to build momentum into 2018.

On May 7, 2016, Duffy hit a walk-off double in the bottom of the 13th inning to defeat the Colorado Rockies 2–1. On June 21, Duffy was placed on the disabled list with an Achilles injury. For the season with the Giants, he batted .253/.313/.358.

On August 1, 2016, the Giants traded Duffy to the Tampa Bay Rays along with Lucius Fox and Michael Santos for Matt Moore. Duffy made his Rays debut on August 12, he went 1–4 with a single. On September 7, the Rays shut Duffy down for the season to have surgery on his Achilles. With the Rays in 2016 he batted .276/.300/.355.

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. On June 27 and 28, Duffy came up one hit short of hitting for the cycle in back-to-back games, needing a triple the first time and a single the next day. On July 10, Duffy had a career-high four hits in a 15–2 rout of the Philadelphia Phillies. 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. For the third time, Duffy came up one hit shy of hitting for the cycle, needing a home run this 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/.334/.428 with 12 home runs, 6 triples, 28 doubles, 169 hits, and 77 runs scored.

He recorded 16 hits and 5 runs while batting .267/.302/300. In Game 2 of the 2014 National League Championship Series, Duffy scored the tying run from second base on a wild pitch in the top of the ninth inning. He recorded a speed of 20.3 miles per hour when he raced from second to home. Duffy was also one of five rookies eligible to play against the Royals in the 2014 World Series. 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.
