Craig Kimbrel
The Boston Red Sox were baseball's most dominant team in 2018 en route to winning their 4th World Series since 2004, and most of that came on the back of their young stars J.D Martinez and Mookie Betts, but their pitching staff and bullpen were also great. The staff got a number of great contributions from the likes of Chris Sale, David Price and surprisingly Nate Eovaldi, but it was the bullpen that shined brightest at the back end of the season.
They were up and down throughout the year, but led by Craig Kimbrel, they turned it on when necessary, and given how much the arch rival Yankees have improved this offseason, they need to retain him. The Yankees already had plenty of stars in the field and the 'pen, but they've signed Adam Ottovino in a bid to improve the already dominant 'pen, and the Kimbrel-Red Sox match is one made in heaven, so there's no point changing that.
Prediction: Boston Red Sox
