Monday's US Open first round pits Alexander Blockx against Tomas Barrios Vera on hard. Alexander Blockx has won 4 of the last 10. Tomas Barrios Vera is searching for form, having lost 7 in a row (2 of the last 10).

The serve is where this match separates: Blockx has been winning 74.3% of first-serve points to Vera's 64.9%, and on hard that gap compounds fast. Blockx should have enough here, though Vera has the tools to make the scoreboard uncomfortable.
