Lourdes Gurriel Jr. Returns to Diamondbacks After ACL Recovery

The Arizona Diamondbacks have reinstated outfielder Lourdes Gurriel Jr. From the 60-day injured list and designated infielder Luken Baker for assignment, the team announced on April 18, 2026. The moves come as Gurriel Jr. Returns to active duty less than eight months after undergoing anterior cruciate ligament (ACL) surgery, marking a significant acceleration in his recovery timeline.

Gurriel Jr. Suffered the ACL tear during spring training in March 2025, an injury that initially sidelined him for the majority of the 2025 season. His return to the 40-man roster now positions him to make his 2026 season debut, potentially as early as the Diamondbacks’ upcoming series against the Toronto Blue Jays beginning April 25 at Chase Field. Arizona manager Torey Lovullo confirmed the possibility of Gurriel Jr.’s activation for that series, noting the outfielder’s progress in baseball activities has exceeded expectations.

Accelerated Recovery and Roster Implications

The Diamondbacks’ medical and training staff have overseen a rehabilitation protocol that allowed Gurriel Jr. To begin baseball-specific drills in January 2026, followed by gradual integration into full-team practices by mid-March. His activation reflects both the success of that program and the club’s assessment that he is physically prepared to contribute at the major league level. Gurriel Jr. Has participated in simulated games and live batting practice over the past two weeks, demonstrating restored range of motion, explosive lateral movement, and consistent swing mechanics.

Luken Baker Designated for Assignment

To create roster space for Gurriel Jr.’s return, the Diamondbacks designated Luken Baker for assignment. Baker, who was acquired off waivers from the Pittsburgh Pirates in November 2025, appeared in 12 games for Arizona this season, batting .182 with two runs batted in and no home runs. He was primarily used as a pinch-hitter and defensive replacement at first and third base. Baker now has seven days to be traded, released, or outrighted to Triple-A Reno. If no move is made, he will be removed from the 40-man roster.

Context and Season Outlook

The Diamondbacks entered the 2026 season with Gurriel Jr. Listed as day-to-day during spring training, though the club had not ruled out a delayed return depending on his rehabilitation progress. His activation now provides Arizona with an experienced left-handed bat in the middle of the order, a role he held before his injury when he posted a .284 batting average with 18 home runs and 62 RBIs in 98 games during the 2024 season.

Gurriel Jr.’s return adds depth to an outfield that has seen inconsistent production early in 2026. His ability to play both corner outfield positions provides managerial flexibility, particularly as the Diamondbacks navigate a competitive National League West race. The team is currently 9-11 through its first 20 games, sitting third in the division behind the Los Angeles Dodgers and San Diego Padres.

The upcoming series against the Blue Jays represents Gurriel Jr.’s first opportunity to face American League competition since the 2023 season, when he played for the Boston Red Sox before being traded to Arizona in the offseason. Toronto enters the series with a 10-10 record, having split its first four games against the Diamondbacks in 2025.
