The Yankees are off to their worst start to a month this season, but it’s not because of their bullpen. In fact, of their eight losses in August, the only one lost by a reliever was when Mariano Rivera allowed a walk-off homer to the Rangers.
The big four that have made the most difference are Boone Logan, David Robertson, Joba Chamberlain and Kerry Wood. Here’s a look at all four of their great stretches:
| Player | Since | G | IP | K | BB | ERA |
| Logan | 7/21 | 12 | 8.2 | 9 | 1 | 0.00 |
| Robertson | 7/4 | 16 | 15.2 | 21 | 9 | 0.00 |
| Chamberlain | 7/28 | 9 | 8.2 | 6 | 3 | 0.00 |
| Wood | 8/1 | 6 | 7.0 | 9 | 4 | 1.28 |
