Kirk Gibson announced Arizona's starting rotation on Monday. Ian Kennedy will be followed, in order, by Daniel Hudson, Josh Collmenter, Trevor Cahill and Joe Saunders. Arizona is apparently playing the matchups early with Cahill, which doesn't seem like an endorsement from his new team. The 26-year-old Collmenter, meanwhile, will need to perform early to hold off Trevor Bauer and Tyler Skaggs. The right-hander is winless in three starts this spring, and owns a 9.75 ERA over 12 innings.
