Diamondbacks make a flurry of roster changes

The Arizona Diamondbacks have announced a handful of roster moves on Thursday. Infielder Ildemaro Vargas, catcher James McCann and left-hander Jalen Beeks have elected free agency. Right-handers Austin Pope, John Curtiss and Casey Kelly, left-hander Kyle Nelson and infielder Connor Kaiser were outrighted off the 40-man roster. Arizona’s 40-man roster now sits at 38 players.

Vargas just wrapped up his third stint with the team. The versatile utilityman debuted with the Diamondbacks in 2017. After playing a minor role across three seasons, Arizona designated him for assignment in 2020. The DFA led to a trade to the Twins, though Minnesota would also designate Vargas for assignment less than a month after acquiring him. The Cubs scooped him up off waivers for the final month of the season. Vargas went through a similar set of transactions in 2021, just in a different order. He was claimed off waivers by the Pirates in May, then designated for assignment a couple of weeks later. Pittsburgh worked out a trade that sent Vargas back to Arizona.

Washington gave Vargas his longest look to date. The Nationals signed him as a minor league free agent in May 2022. He hit .280 in 53 games with the team. Washington gave Vargas semi-regular playing time over the next two seasons. He topped 300 plate appearances for the first time in 2024. Vargas signed a minor league deal to return to Arizona this past offseason. He appeared in 38 games with the team in 2025. Vargas has spent time at all four infield positions, plus left field and right field. He’s also made five appearances in mop-up duty on the mound, hilariously allowing just two earned runs in five innings. The 34-year-old’s extreme versatility could get him another gig this offseason.

Arizona added McCann after Atlanta cut him loose in June. He appeared in 42 games for the team, filling in behind the plate after Gabriel Moreno went down with a hand injury. The 34-year-old posted a solid 110 wRC+ in limited action.

Beeks ended up being a decent find for the Diamondbacks. They signed him just before the season began, and the veteran lefty contributed a 3.77 ERA over 57 1/3 innings. Beeks missed time with a back injury, but still managed to make 61 appearances, including two as an opener.

Curtiss is the only member of the DFA group to make a significant impact at the MLB level in 2025. He appeared in 30 games with the big-league club, recording a 3.93 ERA. Curtiss has bounced around frequently since debuting in 2017, pitching for eight different teams.

Nelson has been a part of Arizona’s bullpen in recent years, but he only appeared in three games this past season. Pope debuted in September, making a two-inning appearance against the Dodgers before heading back to Triple-A Reno. Kelly pitched in two games in August. Kaiser had a couple of brief stints with the big-league club, going 2-for-18 across 11 games.
