Will Jessica Pegula and Tommy Paul avoid second-round upsets at the Australian Open?
Paul survived a comeback bid by Australia’s Chris O’Connell in front a feverishly partisan crowd; the American tightened up when he served for the match in the fourth set, then fought through a shoulder injury to take the decider 7-5. Nishikori, meanwhile, came back from two sets down, and saved two match points, against Thiago Monteiro.
