Gyorko began the season as the Padres starting second baseman but recently lost the job to Cory Spangenberg.
After hitting .135 with no home runs and two RBIs in April, Gyorko hit .279 with two home runs and eight RBIs in May.
As a rookie in 2013, the 26-year-old Gyorko hit .249 with 23 home runs and 63 RBIs and finished sixth in the NL Rookie of the Year voting. He was given a five-year, $35 million extension in April 2014 but saw his numbers dip across the board last season, hitting .210 with 10 home runs and 51 RBIs.
To fill Gyorko's spot on the roster, the Padres recalled right-handed pitcher Nick Vincent from Triple A.
San Diego (30–30) plays the Braves in Atlanta on Wednesday.
