The Houston Rockets have made a late-summer tweak to their roster depth, swapping out one of their two-way contract slots as the countdown to training camp begins. Just over a month before camp opens, the team replaced guard Tristen Newton with center Rafael Castro, a move that signals a focus on frontcourt reinforcement. Castro, a 6-foot-10 big man, went undrafted in June after playing for Providence College and then George Washington University. He spent the summer competing in the NBA Summer League with the Milwaukee Bucks, appearing in games in both California and Las Vegas. While his collegiate numbers show an average of 14.6 points over his final two seasons, his reputation is built on defense. Castro earned a spot on two All-Defensive Teams in the Atlantic 10 Conference, showcasing his shot-blocking and rebounding instincts. Born in New Jersey and of Dominican heritage, he now joins a Rockets organization that values versatility and defensive grit. Castro becomes the third two-way player on Houston's roster, alongside point guards Quadir Copeland, who came out of North Carolina State, and Sam Pedulla, who played at Virginia Tech and Ole Miss. Pedulla brings notable credentials: he was named the G-League Rookie of the Year last season, posting averages of nearly 24 points, seven assists, and five rebounds. The Rockets recently signed Pedulla and parted ways with JD Davison, who had been with the team the prior season. Two-way players are allowed to suit up for up to 50 games with the parent club before needing to be converted to standard NBA contracts or be released. It is likely that all three will spend time with the Rio Grande Valley Vipers, Houston's G-League affiliate, if they remain with the organization through training camp. The Rockets' core rotation is largely solidified, even as the front office has intentionally left the 15th standard roster spot open. This vacancy is a strategic move for salary-cap flexibility and tax considerations, while also keeping the team nimble to pounce on veteran options that may become available as the season unfolds. The offseason has already brought significant reinforcements: Fred Van Vleet and Steven Adams are back from injury, Marcus Smart was acquired in free agency, and rookie Bruce Thornton—a potential second-round steal—impressed during summer league. However, the path to playing time for the two-way players is narrow. Castro will have to wait behind Alperen Sengun, Adams, and the returning Clint Capela, as the Rockets look to develop his offensive game. The backcourt is even more crowded, with Van Vleet, Smart, and Reed Sheppard expected to handle the bulk of ball-handling duties. If Copeland or Pedulla see significant minutes in the regular season, it would likely mean injuries or unexpected roster shuffling. As the Rockets aim to close the gap on divisional rivals like San Antonio, Oklahoma City, and Minnesota, consolidation trades remain a possibility. These moves could open brief windows for younger players at the tail end of the roster. For now, the team is betting on Castro's defensive upside and Pedulla's G-League production to add depth, while keeping a watchful eye on the market for veteran upgrades.
