#1 Randy Orton
Randy Orton made his long-awaited return on SmackDown Live this week. The Viper's last match was at Super ShowDown where he fought Triple H. Following the match in Saudi Arabia, Orton skipped Stomping Grounds and Extreme Rules. Since Orton is back in action, he is likely to have a big match at SummerSlam.
Orton confronted Kofi Kingston on the Blue Brand this week. The Viper mentioned that the gold hasn't been around his waist for a long time and he wants to win the title from Kingston. Following the segment, Orton and Kingston cross paths in a Six-Man Tag Team Match where the Viper pinned the WWE Champion.
Orton certainly made a huge statement by pinning Kofi Kingston this week. Judging by Orton's segment on SmackDown Live, he could go for the WWE Title at SummerSlam. Orton is a classic heel, while Kingston is currently a top babyface of the Blue Brand, so they could deliver an exceptional rivalry.
