Spiers allowed three hits and struck out four over two scoreless innings in Saturday's spring start against the Guardians.
Spiers, who served dual roles as a starter and reliever in 2023, opened the Cactus League schedule for the Reds as a starter. The performance was an encouraging outing for Spiers, as two of his four punchouts came against players that rarely strike out -- Steven Kwan and Jose Ramirez. It would be a surprise if the right-hander wins a rotation spot, but a strong spring could keep Spiers on a starter's trajectory and put hm atop the list of depth starters.
