The Cardinals have optioned second baseman Kolten Wong to Triple-A Memphis, according to a club announcement. Jhonny Peralta, who has missed the entire season to this point, will be activated off the disabled list Tuesday.
Wong, 25, has hit just .222/.306/.286 with one home run in 49 games for St. Louis this season. He had a strong 2015 season, hitting .262/.321/.386 with 11 homers in 150 games, and was rewarded by the Cardinals in March with a 5-year, $25.5 million extension through the 2020 season.
Wong will go back to Memphis, where he hasn't played since the 2014 season, to try to improve upon his struggles and work his way back to being a major-league contributor by the end of the season. In the meantime, the Cardinals will keep breakout star Aledmys Diaz at shortstop, use Peralta at third base and shift Matt Carpenter to second while Jedd Gyorko provides depth.
In parts of four major-league seasons, Wong owns a career .247/.303/.365 line with 24 home runs and 108 RBI.
