Young 2.20, Sousa 1.78
This will be their first meeting.
Slightly better overall results for Young last year. He won 53% of her matches in 2017 compared to 47% for Sousa. He was also stronger on hard courts with 56% of matches won. Sousa won 44%.

Sousa reached the final in Auckland last year losing in 3 sets to Jack Sock. He performed better on indoor courts and has won just 3 of his last 10 outdoor hard court matches.
I think the sets will be very tight. Backing servers is an option. Value on Young to take at least a set. Sousa would have to be a lay below 1.50.
Update: Sousa got the first break of serve in the opening set. Young broke back and took the set in a tie break. Sousa took the match in 3 sets.
Sousa won 6-7, 6-4, 6-2.
