The Tigers are getting a late-season youth infusion with two of their top infield prospects. Jace Jung, the Tigers’ No. 5 prospect in MLB Pipeline’s updated midseason rankings, and No. 20 prospect Trey Sweeney are expected to be promoted from Triple-A Toledo on Friday for their Major League debuts against the Yankees, sources told MLB.com.

The Tigers have not confirmed the promotions, which are expected to be officially announced on Friday along with the corresponding moves for the 26- and 40-man rosters. Manager A.J. Hinch hinted that moves were coming when he talked after Thursday’s 2-1 win over the Mariners.

“We have a lot of room to grow. We’re going to get younger,” Hinch said. “We’re also going to get better. And we continue to fight because we know that we can play complete games.”

ESPN’s Kiley McDaniel first reported the Sweeney call-up. Evan Petzold of the Detroit Free Press initially reported the Jung call-up.

Both Jung and Sweeney were initially in the Mud Hens' lineup Thursday night at Charlotte before being scratched shortly before first pitch. The Tigers don’t normally do midweek promotions barring injury replacements, but the moves coincide with a notable date: With 45 days left before the end of the regular season, players without Major League service time can be called up Friday and remain through the season while retaining their rookie status for next year.

Jung, the Tigers’ first-round pick in 2022 after a standout college career at Texas Tech, is the younger brother of Texas Rangers third baseman Josh Jung, and sits 64th on MLB Pipeline’s Top 100 prospect list. The left-handed hitter with a hard-nosed style of play and a unique left-handed swing slashed .257/.377.454 with 14 home runs, 60 RBIs and a 117 wRC+ at Toledo this season, with a brief interruption in June on the injured list with right wrist soreness. The 23-year-old posted a .912 OPS against right-handed pitching.

Jung has spent most of the season at third base, having shifted from second base during last year’s Arizona Fall League. He still got occasional playing time at second, but he’s expected to work primarily at the hot corner in Detroit, where Colt Keith has blossomed into the everyday second baseman while building a case for AL Rookie of the Year consideration.

Sweeney joined the Tigers system upon arriving from the Dodgers in the Jack Flaherty trade on July 30. He hit the ground swinging with Toledo, batting .381 (16-for-42) with six doubles, two home runs and nine RBIs in 11 games, nine at shortstop. Like Jung, the 24-year-old Sweeney is a left-handed hitter who does particular damage against righties with an .866 OPS, making him a potential complement at shortstop with Javier Báez, whose go-ahead two-run home run in Thursday’s eighth inning powered Detroit to victory.
