As Jay said in his recent ATP interview ( Bob posted a link on Jay's thread ) many of these challengers are very competitive, seeds vs non seeds vs qualifiers. As indeed often shown in the results.
Anyway, Jay breaks against this particular qualifier.
Doing a very good job at protecting his second serve.
Overall 1st serves in 60%, 1st serve points won 61% (19/31) but 2nd serve points won 67% (14/21) and 77% (10/13) in that second set. Looks as if he's having to work hard for it but working well of late.
