LHP Aroldis Chapman is the second-best reliever in baseball, while RHP Dellin Betances is the ninth-best, according to a Top 10 list released by the MLB Network.
LHP Andrew Miller, who the Yankees traded to the Indians last July, was ranked as the best reliever in baseball.
The list is compiled after taking into account "player performance over several seasons with an emphasis on 2016," as well as "projected perforrmance for the upcoming season."
The 28-year-old Chapman, who signed a five-year deal with the Yankees this offseason after being traded to the Cubs in July, had a 2.01 ERA (1.93 FIP) and 0.89 WHIP while striking out 44 batters in 31 1/3 innings (31 appearances) and saving 20 games for the Yankees last season before the trade.
He posted an overall ERA of 1.55 (1.42 FIP) and 0.86 WHIP while striking out 90 batters in 58 innings (59 appearances) in 2016.
Betances, 28, had a 3.08 ERA (1.78 FIP) and 1.12 WHIP while striking out 126 in 73 innings (73 appearances) last season.
Chapman is expected to serve as the Yankees' closer this season, while Betances works in a setup role.
