#4 Bobby Lashley wins clean

As mentioned on the first slide, although it would further damage Strowman's credibility if he lost to Lashley in Saudi Arabia, it wouldn't surprise me if Lashley is booked to win. He's a favorite of 'the Chairman' due to his physique and if he did win, he could stake a claim to a Universal Championship shot in the future.
Lashley's return hasn't been as successful as both he and WWE would have wanted, but at least he hasn't been booked to lose so many matches for the Universal Title like Strowman has. Lashley has recovered from losing to some of the other faces like Finn Balor or Seth Rollins, but physically, Strowman beating Lashley is believable.
It would also be somewhat believable for Lashley to defeat Strowman. He displayed his power on Raw by power slamming 'the Monster', and power like that often gets rewarded by Creative. If the match is longer and Lashley wins, it would not be as bad as if 'the Almighty' won a quick squash match.
