2:12pm: Francona said De La Cruz will probably miss two to four weeks, per Mark Sheldon of MLB.com.

11:36am: The Reds announced Monday that they’ve placed star shortstop Elly De La Cruz on the 10-day injured list due to a strained right hamstring and recalled top infield prospect Edwin Arroyo from Triple-A Louisville for his major league debut. Cincinnati also selected the contract of lefty Brandon Leibrandt and designated right-hander Yunior Marté for assignment in a corresponding move. Francys Romero of BeisbolFR.com reported that the Reds would place De La Cruz on the IL and promote Arroyo shortly before the formal team announcement.

De La Cruz suffered his hamstring injury in Sunday’s game. Upon driving a ball into the right-center field gap for what looked like an easy double — if not a triple, given his speed — he instead pulled up at first base in obvious pain (video link). A quick visit from the training staff concluded with an early exit from the game. He subsequently underwent an MRI that revealed the strain. Cincinnati has not yet provided a possible timeline for his potential return or revealed the grade of hamstring strain with which De La Cruz has been diagnosed. Manager Terry Francona will likely provide more details prior to tonight’s game against the visiting Royals.

An injury to the 24-year-old De La Cruz is about as impactful an injury absence as possible for Cincinnati. The switch-hitting dynamo was putting together perhaps the best season of his exciting young career, delivering a .280/.346/.509 slash (134 wRC+) with a dozen homers, 13 doubles (14, were it not for this injury), five triples and 10 steals. He’s hitting for power at the highest rate of his career, and after struggling immensely from the right-handed batter’s box through the first three seasons of his career, De La Cruz was having a breakout showing in that regard as well (.299/.342/.642 in 73 plate appearances versus southpaws).

If there’s a silver lining for Reds fans, it’s that the De La Cruz injury serves as a catalyst for the promotion of Arroyo — one of the hottest-hitting prospects in all of Minor League Baseball at the moment. A fellow switch-hitter, Arroyo is just 22 years old but was laying waste to Triple-A pitching with a .323/.383/.562 batting line through an even 250 plate appearances. He’s homered 11 times and added nine doubles, five triples and nine steals. He’s been hitting at a particularly absurd level over the past month: .368/.406/.705.

Originally drafted by the Mariners with the No. 48 overall pick back in 2021, Arroyo was traded to the Reds as part of the deal sending Luis Castillo back to Seattle. He was a consensus top-100 prospect at the time. His stock dipped in subsequent seasons, in no small part due to a shoulder injury that required surgery and wiped out his entire 2024 season. However, Arroyo’s torrid 2026 output has thrust onto the tail end of the top-100 lists at MLB.com and Baseball America. ESPN’s Kiley McDaniel listed him as the top riser in Cincinnati’s system just this morning, noting that Arroyo’s power looks to be back in full force after an understandable dip last year in the return from that shoulder operation. Arroyo hit just three long balls in 120 games last year.

Arroyo has primarily been a shortstop in his professional career, but he’s played some second base and third base in recent seasons as well — likely in recognition that shortstop isn’t going to be opening up in Cincinnati anytime soon, so long as De La Cruz remains healthy. He’ll step into De La Cruz’s shortstop spot for the time being, but if Arroyo hits the ground running, it’s not at all out of the question that he could parlay this initial call to the majors into a more prominent role at third base and/or second base once De La Cruz returns. Neither third baseman Ke’Bryan Hayes nor second baseman Matt McLain has hit at all this season — and that’s egregiously true in the case of the former (.142/.195/.225 in 128 plate appearances). Hayes is currently on the injured list a disk injury in his back, continuing a long history of back ailments.

The 33-year-old Leibrandt is the son of former big league pitcher Charlie Leibrandt. He’s pitched in parts of two minor league seasons: the 2020 campaign with Miami and the 2024 season with Cincinnati. He’s allowed nine runs in 15 1/3 major league frames. The younger Leibrandt has been tagged for a 5.23 ERA in 11 Triple-A starts this season, though a disproportionate amount of the damage against him came in his most recent start. Leibrandt logged a solid enough 4.29 ERA through his first 10 starts before being tattooed for six runs in just 1 1/3 innings against the Twins’ Triple-A club last time out.

Injuries have thinned out both the Cincinnati bullpen and rotation. The Reds have Hunter Greene, Rhett Lowder and Brandon Williamson all on the injured list. Depth starters like Chase Petty, Julian Aguiar and Jose Franco have pitched poorly in Triple-A. The Reds already brought veteran Chris Paddack aboard following his release in Miami; he’s allowed a total of nine runs with eight strikeouts against seven walks across a trio of five-inning starts. In the bullpen, relievers Graham Ashcraft, Emilio Pagan and Pierce Johnson are on the injured list; Ashcraft was recently placed directly on the 60-day IL due to a UCL sprain.

Marté, 31, was just called up last Friday when Ashcraft hit the IL. The journeyman right-hander appeared in one game, faced six batters and allowed five of them to reach. He wound up being charged with four runs in one-third of an inning. Marté has pitched in parts of four MLB seasons, totaling 113 2/3 innings with a 5.94 ERA. He throws hard and can miss bats but has regularly shown shaky command while struggling to limit damage against left-handed hitters in particular. He’ll be traded, placed on waivers or released within the next five days.
