The Reds announced that they have added three players to the 40-man roster. Infielders Edwin Arroyo and Leo Balcazar had their contracts selected from Double-A Chattanooga, while outfielder Hector Rodriguez was selected from Triple-A Louisville. All three are now protected from the Rule 5 Draft. In addition, right-hander Carson Spiers was designated for assignment. The club’s 40-man roster now stands at an even 40.
Arroyo, 22, was originally a second-round draft pick by the Mariners in 2021. He was one of four prospects who went to Cincinnati in the Luis Castillo trade in July 2022. He spent most of 2023 at High-A but earned a promotion to Double-A in September of that year despite being just 19 years old. However, injury struck in March 2024, as Arroyo suffered a torn labrum in his left shoulder while diving back to the bag on a pickoff attempt. The resulting surgery wiped out his 2024 season. He was a non-roster invite to spring training in 2025 and returned to Double-A Chattanooga for his first full season there, save for a brief stint on the injured list in April for a left hamstring strain.
In 120 games for Chattanooga in 2025, Arroyo batted .284/.345/.371 while scoring 63 runs and chipping in 12 stolen bases. That output was good for a 107 wRC+. Arroyo decreased his strikeout rate to 16.9% in 2025 after sitting at 21.3% across High-A and Double-A in 2023. His walk rate declined from 8.8% to 7.7%, though that is not surprising given the difficulty of the jump to Double-A. MLB.com lists Arroyo as the Reds’ No. 8 prospect and considers him a decent hitter with untapped power potential, though his calling card is his plus defense at shortstop. He figures to spend most 2026 at Triple-A.
Rodriguez, 21, was signed by the Mets as an international free agent in January 2021 and was traded to the Reds in July 2022 in the Tyler Naquin deal. He split the 2025 season between Double-A and Triple-A, batting .298/.357/.481 with a 140 wRC+ in 82 games for Chattanooga. However, Rodriguez hit a wall upon reaching Triple-A, with an 85 wRC+ in 50 games. His walk rate declined to 5.2% after sitting at 8.1% in Double-A. His strikeout rate also increased from 13.9% to 16.5%, although the latter figure is still good and bodes well for his contact ability. The switch-hitter is considered the Reds’ No. 9 prospect and a solid baserunner, though he’ll likely move off of center field for one of the corners long-term.
Balcazar, 21, was signed by the Reds as an international free agent in January 2023 and split the 2025 season between High-A and Double-A. In 75 games at High-A, he posted a 110 wRC+ along with a 14.9% strikeout rate and an 8.5% walk rate. Though his wRC+ declined to 100 in 51 games at Double-A, his strikeout (11.1%) and walk rates (10.6%) both improved over his High-A numbers. MLB.com lists him as the club’s No. 23 prospect. Since his recovery from a torn ACL in 2023, he has proven himself a decent defender at shortstop, though he will continue to get reps at second base as well.
As for Spiers, his DFA was unsurprising given that he underwent elbow surgery in July and was expected to miss most or all of next year. The right-hander was signed as a non-drafted free agent in 2020 and pitched 117 big-league innings with a 5.69 ERA from 2023-25. The bulk of those innings came in 2024, when he made 22 appearances (10 starts) with a 5.46 ERA, a 19.5% strikeout rate, and a 6.6% walk rate. He made just three appearances (two starts) in 2025, all in April, before going on the injured list with a right shoulder impingement on April 20. He was pulled from a rehab assignment in early July with biceps tightness and underwent an MRI, which revealed the more serious UCL damage. It was unclear whether Spiers underwent Tommy John surgery or an internal brace procedure, but the most likely outcome is that he’ll be out until the start of the 2027 season.
