San Diego Padres second baseman Jake Cronenworth has been sidelined on the seven-day injured list Tuesday after experiencing concussion symptoms.
To replace Cronenworth on the roster, the Padres brought up infielder Sung-Mun Song from their Triple-A affiliate in El Paso.
The organization has not disclosed details about when the 32-year-old Cronenworth may have suffered the potential head injury. The veteran player has faced challenges at the plate during the early portion of the 2026 season, posting a .144 batting average and .196 slugging percentage with just one home run and four RBIs across 32 games. Throughout his seven-year major league career spanning 813 games, he maintains a .244 batting average.
For the 29-year-old Song, this call-up marks his first opportunity in the major leagues. He joined the Padres organization this past offseason, signing a four-year contract after developing his skills in Korea’s KBO league. An oblique injury initially landed him on the injured list to begin the season, and following his recovery, he was assigned to El Paso where he has performed well, batting .293 with one home run and 15 RBIs over 25 games.
Song wasted no time making his mark, earning his inaugural major league start Tuesday against San Francisco, taking the field at second base while hitting ninth in the batting order.
The Padres made additional roster adjustments Tuesday, bringing back left-handed pitcher Yuki Matsui, 30, from the 15-day injured list where he had been recovering from a groin strain. To make room, they sent lefty Kyle Hart, 33, down to El Paso. Hart compiled a 0-1 record with a 5.40 ERA, issuing six walks while recording 10 strikeouts across 16 2/3 innings in 12 relief outings.
