Suffered season ending injury
Castro is out for the season with a right knee injury, Jesse Rogers of ESPN.com reports.
ANALYSIS
Castro injured his right knee as he slipped while trying to cover first base against the Mets on Wednesday. He had to be removed from the game as he was helped off the field by trainers, but the injury was tabbed as soreness initially. The specifics of the injury are yet to be disclosed, but the severity is certainly not good.

Castro's strong performance during Cactus League performance earned him a greater role in Arizona's bullpen out of spring training. The 28-year-old mostly handled setup duties, but he got some run as the D'Backs' closer early in the season. The right-hander compiled 5 saves, 3 wins and 8 holds by the end of May to go along with a 2.22 ERA and 0.99 WHIP. It looked like a breakout season was on the horizon, but Castro opened June with a couple of rough outings and was soon ousted as closer. The right-hander still had a solid season overall, as his 6 wins, 7 saves, 13 holds and 1.18 WHIP were all personal bests. Castro ended 2023 on a high note with a 14-game scoreless streak with 17 strikeouts over 12.2 innings. Look for him to spend most of 2024 in the 6th, 7th and 8th innings.

Demand increasing
Castro could be signed in the coming days, shares Buster Olney of ESPN.
ANALYSIS
Castro logged a 4.03 ERA through 29.0 innings last season, but his 4.87 xERA and 1.45 WHIP are less flattering. Nonetheless, Olney reports a "sense" among MLB executives that "a wave of second-tier free agent relievers is moving fast and on the cusp of landing deals."
