The Diamondbacks recalled Morillo from Triple-A Reno on Monday.

EDGE Analysis

Morillo has offered a mixed bag during his several stints in the majors, posting a 4.55 ERA and 32:20 K:BB over 31.2 innings. Even with his control and command issues, the hard-throwing Morillo has sometimes found himself in high-leverage situations as part of an unsettled Arizona bullpen.

The Diamondbacks optioned Morillo to Triple-A Reno on Wednesday.

EDGE Analysis

Morillo gave up a run on one hit and two walks without recording an out in Tuesday's loss to the Brewers. His latest appearance elevated his ERA to 4.55 to go with his 1.77 WHIP through 31.2 innings with the D-backs, and he'll now aim to get back on track in the minors. Taylor Rashi was promoted from Reno to take Morillo's place in Arizona's bullpen.

Morillo picked up the save Tuesday against the Rangers, throwing a perfect ninth inning with no strikeouts.

EDGE Analysis

The Diamondbacks are still searching for a closer to replace Kevin Ginkel (shoulder), who was shut down for the season in early August. Morillo, a 26-year-old rookie who's bounced between the big leagues and Triple-A during 2025, appears to be in the running for the position. While he has a 4.76 ERA and 28:16 K:BB in 28.1 innings with Arizona this season, Tuesday's performance could have earned him some trust with manager Torey Lovullo. Morillo posted a 3.00 ERA in 15 innings with Triple-A Reno this year.

EDGE Analysis

Morillo has made 31 appearances out of the Diamondbacks bullpen this season, posting a 4.94 ERA and 28:16 K:BB over 27.1 innings. The 26-year-old could work his way into high-leverage appearances as part of an unsettled bullpen, although he's unlikely to be in the mix for save chances right away.

Morillo was optioned to Triple-A Reno following Sunday's game against the Angels.

EDGE Analysis

Morillo got roughed up in Saturday's appearance, surrendering four runs on five hits while striking out one over one inning of work, which seems to have led to his demotion. Arizona has yet to make a corresponding move.

Morillo allowed four runs on five hits while striking out one over one inning in Saturday's 10-5 loss to the Angels.

EDGE Analysis

Morillo, who entered the game to begin the eighth inning with a 0.82 ERA over his previous 14 outings, let a one-run deficit balloon to five by the time he was done. In the wake of several bullpen injuries, the rookie's name was recently floated for high-leverage situations, but he was not up to challenge Saturday. Although walks didn't play a role in Saturday's performance, control has been a challenge for Morillo, who owns a 5.3 BB/9.

Morillo is expected to pitch in high-leverage situations after Shelby Miller (forearm) was placed on the 15-day injured list, Alex Weiner of Arizona Sports reports.

EDGE Analysis

Miller had taken over the closer role following season-ending injuries to A.J. Puk (elbow) and Justin Martinez (elbow). Miller's injury leaves manager Torey Lovullo scrambling to fill out the late-game crew. Kevin Ginkel saved Monday's game after Morillo finished out the eighth inning. Morillo, fellow rookie Kyle Backhus and Jalen Beeks are expected to be part of the mix. The 26-year-old Morillo is 29 games into his MLB career and has a 3.91 ERA and 1.58 WHIP with 26 strikeouts and 15 walks over 25.1 innings.

Morillo was recalled from Triple-A Reno prior to Monday's game against the Padres.

EDGE Analysis

Morillo is taking the roster spot of Shelby Miller, who was placed on the 15-day injured list due to a right forearm strain. Morillo has found success at the big-league level in 2025 and had posted a solid 0.96 ERA with nine strikeouts in his previous 12 appearances (9.1 innings) prior to being demoted to Triple-A on Wednesday.

EDGE Analysis

The 26-year-old's move to the minors will clear a spot on the active roster for Jake Woodford, who signed with the D-backs on Wednesday. Morillo has posted a 4.01 ERA and 1.54 WHIP across 24.2 innings in the majors this year, and he could return to Arizona later in the season if/when the Diamondbacks need a fresh bullpen arm.

The Diamondbacks are expected to option Morillo to Triple-A Reno on Wednesday, Nick Piecoro of the Arizona Republic reports.

EDGE Analysis

Morillo has made 28 relief appearances for the Diamondbacks this season, posting a 4.01 ERA and 25:13 K:BB across 24.2 frames. He'll be replaced on the roster by Jake Woodford, who will offer the Arizona bullpen more length.
