While Seth Rollins hasn't went through the hardships in singles contests in which Diego did, he still suffered a pinfall loss at the hands of monumental underdog Heath Slater. This would prove to be Rollins' first singles pinfall loss in 2014. Rollins has had his fair share of singles matches in 2014, 14 to be exact, but was never pinned during those bouts. That's not to say he's undefeated, as he's lost numerous matches by disqualification, and one to Batista by countout, but Rollins had still competed with the likes of Batista, John Cena, Rob Van Dam, and Dolph Ziggler and not been pinned-- until the incomparable Heath Slater. To find Rollins' last pinfall loss in a singles match, you have to go back to December 30, 2013, in a Monday Night Raw loss to estranged WWE superstar CM Punk. Needless to say, it's more likely that Rollins will gain revenge on Heath Slater in a timely manner.
