Record crowds at the Tiburon Peninsula Club filled the stands to see American Tommy Paul face Germany’s Benjamin Becker. Becker prevailed in two sets to move on to the next round. Paul will partner with Canadian Denis Shapovalov in a doubles match against Marcelo Arevalo of El Salvador and Julio Peralta of Chile in an afternoon match on Wednesday.

Great Britain’s Brydan Klein took on last year’s Challenger champion Tim Smyczek (USA), but had to retire after suffering an injury. Tennys Sandgren also retired and ceded to Michael Mmoh (USA).
