Back end of the Angels rotation stunk on ice last year. The three-way trade with the Dbacks was designed to shore up the rotation, bringing in Hector Santiago and Tyler Skaggs. Skaggs is still in the back of the rotation, but Santiago isn’t: the Angels just demoted him to the bullpen.
The move is considered temporary, but it’s probably deserved. Santiago has posted a 5.19 ERA over his first seven starts and is walking 4.7 batters per nine innings.
Who takes his place in the rotation is unclear.
