Rookie of the Year: Seranthony Dominguez
This was also a pretty easy decision. Since being promoted to the major leagues, Seranthony Dominguez has been the anchor in an otherwise unsteady bullpen.
In 28 appearances, Dominguez has a 1.60 ERA, 1.69 fielding-independent pitching, 0.65 WHIP, and 7.17 strikeout-to-walk ratio. Gabe Kapler immediately started using him in high-leverage situations and he has delivered, recording nine saves and 10 holds while blowing only one save.
Since his debut, Dominguez ranks second in WHIP, ninth in K/BB, eight in opposing batting average, eighth in strikeouts, and 18th in ERA among 164 relievers with 20 or more innings pitched. He has already come in and established himself as one of the top relievers in the game just over two months into his major-league career.
When you think about the fact that this is the first season Dominguez has pitched exclusively out of the bullpen, it only makes his mercurial rise to Philadelphia look even better.
