Reds at Guardians, 3:05 p.m. ET

• Reds: The 10-pitcher battle for five rotation spots begins in earnest on Saturday, when Carson Spiers gets the ball to start. Spiers, a prospect who debuted near the end of 2023, likely has an outside shot at being one of the five starters, but he could still be a depth option if somebody goes down. He can also figure in the mix for one of several bullpen spots up for grabs. — Mark Sheldon

• Guardians: After three seasons away from the organization that housed him for 11 years, Carlos Carrasco will make his return to the rubber for the Guardians on Saturday. Carrasco joined the team on a Minor League deal. Whether he makes the Opening Day roster will be determined by the health of the starting rotation and possible opportunities in the bullpen, but he’s guaranteed a warm welcome in his first spring start. — Mandy Bell
