The LA Angels struck gold with Yusmeiro Petit. Petit eventually was voted as the most valuable pitcher on the Angels team by his teammates. He won the award alongside Andrelton Simmons and Mike Trout, who shared team MVP honors.
Petit did everything for the Angels bullpen this season. He closed games, pitched multiple innings, left runners on base. He was the glue guy that led the Angels bullpen to a top-five ranking in 2017.
Petit won this award with a 2.76 ERA in 2017. He went 5-2 out of the bullpen, and was one of, if not the, best pitcher in high leverage situations.
