Nationals - Dbacks: On June 5, 2026 the Arizona Diamondbacks selected the contract of infielder LuJames Groover, optioned José Fernández to Triple‑A Reno and designated Taylor Rashi for assignment to open a 40‑man roster spot.
Groover, 24, arrives after a strong Triple‑A start this season. At the time of the call‑up he had a.322/.421/.452 line with a 116 wRC+ and three home runs, drawing walks at roughly a 14.5% clip while striking out about 16.8% of the time. The club lists him as a corner infielder by trade and Baseball America ranked him the No. 5 prospect in Arizona’s system, with FanGraphs placing him ninth in the offseason.
The promotion follows a steady professional ascent. A second‑round pick in the 2023 draft, Groover missed time in 2024 with a broken wrist but played 61 games that year and pushed through a full Double‑A season the following year: 123 games with a.309/.399/.434 line, 12 homers and a 120 wRC+, drawing an 11.5% walk rate against a 14.4% strikeout rate. Those numbers are the performance case Arizona cited in turning to him now.
Arizona’s first‑base landscape helps explain the timing. Pavin Smith had just come off the injured list and was projected to see regular work, and while Smith was out the D‑backs covered first base with José Fernández and Ildemaro Vargas, using Adrian Del Castillo at designated hitter. Del Castillo’s offense has been limited this year (.192/.252/.325), and Vargas, after a 27‑game hit streak that bridged last season, has hit just.186/.218/.237 since. Fernández himself showed a striking split: a torrid.342/.359/.500 through his first 78 plate appearances followed by a.180/.232/.225 line across his next 99 plate appearances, a volatility that likely influenced Arizona’s decision to option him back to Reno.
That volatility points to the practical attraction of Groover: high on‑base skill and contact control. The friction is obvious — his power has not tracked with those on‑base numbers this year, with only three home runs in Triple‑A. He offers corner infield defense and very limited experience at second base, which narrows immediate defensive deployment and raises questions about how much of a platoon or bench role he can occupy without more home‑run juice.
Taylor Rashi’s designation created the roster vacancy Groover fills. Rashi signed a minor‑league deal in the offseason, was added to the roster in early April and was optioned to the minors after allowing four earned runs in 3 2/3 innings. His big‑league line stands at 20 innings with a 5.40 ERA, a 29.9% strikeout rate, a 10.3% walk rate and a 44.2% ground‑ball rate; he has averaged barely 90 mph on his fastball and mixes a splitter with slider and curve. The club’s move preserves bullpen depth on the 40‑man while pushing Rashi into uncertainty at the moment.
The immediate roster result is clear: Groover is on the active roster, Fernández is in Reno and Rashi is off the 40‑man. What remains unresolved — and the most consequential question now — is how Arizona will use Groover day to day: as an everyday first baseman, a designated hitter in matchups, or a situational complement to Pavin Smith and the rest of the corner mix. The Diamondbacks have not specified his role beyond the positional possibilities, leaving lineups to be watched closely in the days ahead.
