Gauff's American idols
Starting from the top, Cori 'Coco' Gauff once put her favourite players in order: Serena Williams, Venus Williams, Madison Keys and Sloane Stephens. After defeating one of her idols on Monday at the All England Club, with a straight-sets victory over Venus, the 15-year-old American could end up playing another from that list this week.
Should Gauff defeat Slovakia's Magdalena Rybarikova on Wednesday, she would possibly have the prize of a third round match on Friday against Keys. And, as the qualifier demonstrated against Venus, she doesn't hold back against those she reveres.
Australian moustaches
There is a proud history of Australian tennis players with moustaches doing well at Wimbledon. See John Newcombe, a winner of three singles titles. This summer, Jordan Thompson surely has the most impressive facial hair among all competitors.
While Thompson lost to fellow Australian Nick Kyrgios in the opening round of the gentlemen's singles on Tuesday, he is playing in the doubles alongside another Aussie, former singles champion Lleyton Hewitt, on Wednesday. They face the all-Indian team of Jeevan Nedunchezhiyan and Purav Raja.
History on the line for Wawrinka
Roger Federer isn't the only Swiss man taking a swing at history - and the number nine - with an elegantly destructive single-handed backhand. While Federer is attempting to win Wimbledon for a ninth occasion, Stan Wawrinka has ambitions of becoming only the ninth man in history to complete the ultimate tennis collection, the Career Grand Slam.
After scoring his first major at the 2014 Australian Open, and then landing the 2015 Roland-Garros and 2016 US Open titles, Wawrinka is a Wimbledon run away from the full set. That would make him the fourth man of this generation to win the four majors at least once each, joining Federer, Rafael Nadal and Novak Djokovic.
While Wawrinka isn't as comfortable on the Wimbledon grass as Federer (but then, who is?), he has twice reached the quarter-finals here, in 2014 and 2015. He plays American Reilly Opelka in the second round.
Pliskova's modest record
For a player of her grass court ability, Karolina Pliskova has a modest record at Wimbledon. Until last summer, when she ventured as far as the last 16, the Czech had never even progressed beyond the second round.
Such was Pliskova's level at last week's warm-up event in Eastbourne, she dropped just 19 games on the way to the title, including just five in the final against Germany's Angelique Kerber, the Wimbledon champion.
Pliskova, who is coached by 1994 Wimbledon champion Conchita Martinez, plays Puerto Rico's Monica Puig in the second round.
Power games
Who has the biggest, nastiest forehand in the sport? That's a debate that might be settled on Centre Court on Wednesday when Britain's Kyle Edmund plays Spain's Fernando Verdasco for a place in the last 32.
There are some, including former Grand Slam champion Mats Wilander, who think of Edmund's forehand as the most powerful in tennis. Others suggest that when Verdasco is timing the ball well, his forehand has even more snarl and menace to it.
