Joe Saunders and Ervin Santana both are 5-0 this season and are abouot to enter into an elite group of starting pitching combos that opened the season undefeated. They still would need three more victories combined, without a defeat, to make the list, which was compiled by STATS LLC:

(record listed is when both were undefeated at the latest date; one might have had a longer streak after the other first lost)
