early in the season, the Phillies optioned him to AAA on May 9 in favor of Reid Brignac. Two days later, he broke his clavicle, and spent two months on the disabled list. After a rehabilitation assignment, he performed well at AAA, and earned a call-up to the major leagues, replacing Brignac, whom the Phillies designated for assignment. Overall, Galvis posted his worst offensive season thus far; he hit .176 at the major league level with four home runs and 12 RBIs. After the season, Michael Baumann of Crashburn Alley wrote, "After two years of medical and developmental setbacks, Galvis is still only entering his age-25 season, so it's possible the bat develops from bad to below-average and Galvis turns into something. I wouldn’t count on it, but it's still within the realm of possibility." When the Phillies traded Rollins to the Los Angeles Dodgers prior to the 2015 season, media reports speculated that Galvis and César Hernández were the presumptive nominees to start at shortstop for the upcoming season, likely seeking to bridge the gap between Rollins and J. P. Crawford, the top prospect in the Phillies' organization. Galvis indeed became the team's starting shortstop, where he would remain for the following three seasons. He finished the 2015 season with a .263 batting average in 151 total games played. Galvis had a mixed year in the 2016 season both defensively and offensively. He led all National League shortstops in fielding percentage (.987) and was nominated for a Gold Glove Award, ultimately losing to Brandon Crawford of the San Francisco Giants. Offensively, Galvis collected 20 home runs and 67 RBIs with a .241 batting average in 158 games played. On the other hand, his .274 on base percentage was the lowest of all qualified major league batters. Galvis played all 162 games in the 2017 season, including 155 games started at shortstop. On Opening Day, he hit a home run in the second inning against the Cincinnati Reds, one of 12 he would hit that season. Despite playing every game with the Phillies, Galvis slowly began to lose playing time at shortstop to top Phillies prospect J. P. Crawford following Crawford's September callup. Galvis finished with a .255 batting average and .690 OPS. He also performed well defensively, again leading National League shortstops in fielding percentage and being nominated for a Gold Glove Award, and again losing to the Giants'
