SP - Peralta - 107 ERA+, Lohse - 107 ERA+, Gallardo - 108 ERA+, Garza - 104 ERA+, Nelson - 77 ERA+, Estrada - 87 ERA+, Fiers - 178 ERA+

If Segura and Braun hadn't had down years that could have been a playoff team. Segura went from 4.1 bWAR to 0.9 bWAR. Braun went from 1.7 bWAR (61 games) to 1.2 bWAR (135 games) and that's even with one of the worst 1B position in baseball that season.
