Just so I can satisfy myself with my feeble attempt at pointing out that Mo Rivera is having a better season than Frankie Rodriguez
Rivera 64.3 IP, 35 S, 73 K, 6 BB, 39 HA, 1.54 ERA, 0.699 WHIP
K-Rod 64.3 IP, 58 S, 74 K, 32 BB, 50 HA, 2.38 ERA, 1.275 WHIP
He's just had more opportunities for saves.
