Arizona Diamondbacks Call Up LuJames Groover for MLB Debut, Option Jose Fernandez

The Arizona Diamondbacks opened a three-game series with the Washington Nationals at Chase Field by promoting infield prospect LuJames Groover from Triple-A Reno and making his major-league debut as the starting first baseman (batting fifth). Arizona also optioned rookie Jose Fernandez to Reno and designated right-hander Taylor Rashi for assignment. The lineup change was aided partly by Ildemaro Vargas sitting with soreness after a collision with the Dodgers’ Max Muncy. Fernandez, who homered twice in his March 31 debut, has cooled sharply since late April, hitting .180/.232/.225 over 99 plate appearances. Groover, 24, has produced in Triple-A with a .322 average and a .873 OPS while splitting time between third base and first, and the club is emphasizing his improved defensive versatility.
Diamondbacks manager Torey Lovullo said of Groover’s call-up that, “Groover made his way through this, and he forced us. He’s been swinging a really good bat, has a really nice approach,” highlighting that the promotion is tied to more than just roster need.
Groover’s defensive performance is getting specific attention: at first base this season, he has “yet to commit an error through 134 innings,” according to Arizona reporting.
Ildemaro Vargas’ status was described in more detail ahead of the Nationals series—he had bruises to his thigh, ribcage and neck after colliding with Dodgers third baseman Max Muncy, and though “is alright” and available off the bench, he was slated to miss Friday’s game.
While scouts like Groover’s hit tool, some have questioned his long-term offensive impact—one report notes the concern is “evidenced by his three homers in 208 at-bats this year,” and that he’s still searching for his ultimate defensive home.
Groover’s path to the majors includes notable development milestones: he’s a second-round pick (2023) who “won the Texas League batting title with a .309 average in Double-A during 2025,” and he’s a “.302 hitter for his entire minor league career,” per the Diamondbacks’ coverage.
