A pitcher's E.R.A. can be deceiving (especially for relievers)

Jonathan Broxton, the L.A. Dodgers closer, by almost every measure, is one of the best pitchers in baseball this year. If you only looked at his ERA (Earned Run Average), he would not look as good:

He is 7-0 (most wins of any reliever) with 23 saves (tied for 9th) and only 2 blown saves.

MLB rank: 40 + Innings Pitched

Batting Average Against: 1st - .140

On Base %: 1st - .235

Slugging %: 1st - .191

OPS (On Base % + Slugging %): 1st - .426

Strikeouts/9 Innings: 1st - 14.39 (next closest: Rafael Soriano - Braves: 11.96)

WHIP (Walks + Hits per inning): 5th - .90

ERA: 34th - 2.76

He has allowed runs in only 8 in the 43 games he has appeared in:
0 runs allowed - 35 times
1 run allowed - 3
2 runs - 3
3 runs - 1

He has only allowed 1 home run this year.
Who hit it? Gary Matthews Jr. (Angels), who has been one the worst hitters in baseball this year (.228, 2 HR, .605 OPS). Strange.
