The Arizona Diamondbacks reinstated left-handed reliever Jalen Beeks from the 15-day injured list on Friday after he missed the past three-plus weeks with lower back inflammation.

First baseman Tyler Locklear, acquired from the Seattle Mariners in the Eugenio Suarez trade, reported to the club and will start Friday’s game against the Athletics in Sacramento.

Arizona additionally optioned left-handed pitcher Brandyn Garcia and first baseman Tristin English to Triple-A Reno, while the club selected the contracts of left-handed reliever Kyle Nelson and shortstop Connor Kaiser.

The 40-man roster is back at 40 after Arizona traded several key veterans ahead of Thursday’s trade deadline, including Merrill Kelly and Suarez. The youth movement is not quite in full-swing, it turns out.

Beeks returns a semblance of stability to the bullpen as the team leader in appearances with 42. He’s worked a 4.39 ERA and made three straight scoreless appearances before hitting the shelf.

Locklear, 24, is the No. 6 prospect in Arizona’s farm system, per MLB Pipeline, and will play his first major league game of the season. He debuted last season and hit .156 in 49 plate appearances before getting sent back down. He’s made some adjustments to his hand placement this summer and has been the hottest hitter in Triple-A, as general manager Mike Hazen described.

“We feel like he made some significant adjustments fundamentally with his hands, with his setup and his swing in the middle part of the year, and he was the best hitter in Triple-A from June-on,” Hazen told Arizona Sports’ Wolf & Luke. “We’re gonna work to continue to push the defensive improvements at first base. He’s a great worker. We’ve heard nothing but good things makeup-wise.”

Garcia, 25, heads to Reno after making two appearances with the Diamondbacks after getting traded from Seattle for Josh Naylor. Garcia delivers a 97 mph sinker with a sweeper and slider, a potential future back-end reliever with quality stuff.

English was pushed out by Locklear, as he was getting everyday playing time at first base since Naylor was dealt last week. English is having a great year in the minor leagues (.967 OPS) but has struggled to get going in a brief MLB opportunity at 2-for-22.

Kyle Nelson returns to Diamondbacks

Nelson returns the Arizona bullpen having last appeared in a major league game on April 22, 2024.

The southpaw suffered from thoracic outlet syndrome and missed the remainder of the 2024 season. He made his return for Triple-A Reno in May before getting designated for assignment a month later, passing through waivers and outrighted to Triple-A.

Nelson has a 3.47 ERA in 122 career games pitched for the Diamondbacks, and he made five appearances during the 2023 postseason. In Triple-A this season, he’s worked a 6.35 ERA with 17 strikeouts and nine walks in 22.2 innings.

Kaiser is a 28-year-old infielder who signed a free agent contract with the D-backs last offseason. He played three MLB games for the Colorado Rockies in 2023, his most recent big league experience.

He’s hit .236 in Reno with a .769 OPS and six home runs. He can play all around the infield but has mostly set up at shortstop.
