With the 2012 postseason underway, Alex Remington takes a look at the statistics that might make a difference in each of the four first-round series. Next up is the NLDS featuring the NL West champion San Francisco Giants against the NL Central champion Cincinnati Reds . The first two games will be held at AT&T Park and the first pitch of Game 1 is scheduled for 9:37 ET on Saturday night. 2.65 The Reds' bullpen ERA, best in the majors. And it wasn't all Aroldis Chapman, either: The ERA of all Reds relievers other than Chapman was 2.88, which would have been tied for third in baseball this year, and with the Braves eliminated, it's still better than the bullpen of any other remaining playoff team. They received terrific work from rookies Tony Cingrani and J.J. Hoover, and veterans like Jonathan Broxton, Sean Marshall, and Jose Arredondo. The Reds had seven different relievers who pitched at least 30 innings with an ERA under 3.50, and Broxton was a midseason trade acquisition who gave them 22 1/3 innings of 2.82 ERA ball. If you're going to score on the Reds, score early.
