I was just perusing the MLB statistics page over at ESPN, and noticed some fascinating numbers regarding the Yankee bullpen. Remember, the overall numbers are hindered by the poor performances of players no longer on the roster, making the totals even more fascinating.
The Yankees bullpen is 2nd in MLB in WHIP and K/9, at 1.26 and 8.56 respectively. It is first in K/BB at 2.47, 2nd in BAA against at .233, and first in OBPA (.309). However, it is last in home runs at 58 (leading to a 20th in SLG at .406), which is expected from a team that strikes out plenty of guys, had some bad pitching in April, and plays in a park conducive to long balls. Those factors have lead the Yankee bullpen to have a 4.14 ERA, good for 18th in baseball. That being said, the drastic improvement since April and the stellar peripherals suggest that this is now one of the best bullpens in baseball.
On an individual level, the Yankees have two players in the top 15 in ERA for relievers with at least 20 IP (Hughes, Rivera), 3 in the top 15 of K/BB (Rivera is 1st, Hughes, Aceves), and two in the top 10 for K/9 (Robertson, Hughes). In WHIP, they have 2 in the top 10 (Hughes, Rivera) and 3 in the top 25 (Aceves), and have 2 in the top 10 for OBPA (Hughes, Rivera), 1 in the top 10 for BAA and SLGA (Hughes), and two in the top 20 for OPS (Hughes, RIvera). The obvious conclusion is that the Yankee bullpen is quite excellent, and that Phil Hughes and Mariano Rivera are leading the charge. Go take a look at Hughes’ numbers as a reliever and his rank among the games’ elite firemen. They are mindblowing.
