Williamson (elbow) faced hitters in a live batting practice session Wednesday, Charlie Goldsmith of Fox 19 Now Cincinnati reports.
The left-hander has no restrictions to begin camp after he missed the entire 2025 season while recovering from Tommy John surgery. Williamson will get the chance to compete for a spot in the Reds' Opening Day rotation this spring, but he still has two minor-league options remaining and seems more likely to begin the season at Triple-A Louisville.
