Julio Rodríguez Placed on 7-Day Concussion IL After Being Struck by Throw

The Seattle Mariners placed star center fielder Julio Rodríguez on the seven-day concussion injured list Friday after he was struck in the back of the helmet by a throw during Thursday’s game against the Los Angeles Angels. Rodríguez reported lingering symptoms, prompting the team to initiate mandatory concussion protocol.

The Incident and Medical Timeline

The injury occurred in the bottom of the first inning of Thursday’s 1-0 win. While running from first to third base on a grounder, Rodríguez was hit by a 78.2 mph throw from Angels first baseman Nolan Schanuel, who was attempting to turn a double play. Although Rodríguez initially remained in the game, he was removed in the third inning after his adrenaline faded and he began experiencing lightheadedness, according to MLB.com.

Rodríguez arrived at T-Mobile Park on Friday still feeling the effects of the impact. Team officials determined that a period of rest was necessary, leading to the placement on the seven-day concussion list. Manager Dan Wilson emphasized the need for caution regarding head injuries, noting that the team’s priority is to allow Rodríguez to recover without rushing his return to the field.

“As he kind of said last night when he got over there, I think when the adrenaline of the moment kind of ran out, he kind of felt lightheaded at the time. And he just wasn’t feeling himself. He kind of came in today and didn’t feel himself again.”Dan Wilson, Mariners Manager, via MLB.com

Roster Adjustments and Replacement Strategy

To fill the vacancy on the active roster, the Mariners selected utility player Miles Mastrobuoni from Triple-A Tacoma. Mastrobuoni, who was designated for assignment last month, cleared waivers and remained in the organization, providing the team with much-needed positional versatility. As reported by MLB Trade Rumors, Mastrobuoni has experience at nearly every defensive position, though he has not played center field at the major league level.

Julio Rodríguez Can't Stop Hitting

The team also transferred right-handed pitcher Cooper Criswell to the 60-day injured list to clear a spot on the 40-man roster. Criswell, who was initially sidelined with a pectoral strain that was later reclassified as a right shoulder issue, is not eligible to return until early August, according to Lookout Landing.

Impact on the Mariners’ Lineup

The absence of Rodríguez, who is hitting .259/.323/.424 with 12 stolen bases this season, represents a significant blow to the Seattle offense. In the immediate aftermath, the Mariners have turned to Victor Robles to handle center field duties. Robles, who was also hit by a pitch during the same game, remained in the lineup for Friday’s contest.

Impact on the Mariners' Lineup

The team is currently managing several other minor injuries as well. Luke Raley, who recently returned from a forearm issue, remains an option for center field, while Dominic Canzone continues to play through a hamstring concern. Despite the injury-riddled week, management remains focused on maintaining consistency.

“Obviously, with head injuries, you have to be so careful. And so I think giving him the extra time and precaution is definitely the way to go at this point.”Dan Wilson, Mariners Manager, via MLB.com

Looking Ahead to the All-Star Break

Rodríguez is eligible to return as early as next Friday, when the Mariners begin a series at Tropicana Field. However, with the All-Star break approaching the following week, the club may choose to exercise additional caution. Whether Rodríguez returns before or after the break will depend on his ability to ramp up baseball activities without experiencing a recurrence of concussion symptoms.

For now, the team is taking a day-by-day approach to his recovery. As Wilson noted, the immediate goal is for Rodríguez to focus on rest before gradually reintroducing physical activity.

“I think it’s just a matter of what he’s going to be able to handle. Today is a day for him to kind of stay down and not do too much. And then I think that, hopefully as he can handle things, we can start to ramp back up.”Dan Wilson, Mariners Manager, via MLB.com
