#3 WWE United States Championship Tournament (2017-18)
Dolph Ziggler won the United States Championship in 2017 at the Clash of Champions PPV, defeating Baron Corbin and Bobby Roode in a triple threat match. The ShowOff vacated the title soon after winning it, and 'left' WWE.
SmackDown GM Daniel Bryan announced an eight member tournament to crown the US champ, with Jinder Mahal, Bobby Roode, Mojo Rawley, Xavier Woods, Zack Ryder, Tye Dillinger, Baron Corbin, and Aiden English as its participants.
Roode, Mahal, Rawley, and Woods progressed to the semi-finals, which saw The Glorious One and The Modern Day Maharaja win their matches to fight in the final. The final match was set to take place at the Royal Rumble PPV.
However, the company preponed it, scheduling it on the same night the semi-finals took place. Bobby won the title by defeating Mahal in the final. The tournament seemed a bit rushed, and even the wrestling quality was not upto the mark. I give this US tournament a "B".
