Body armour isn't ever required at the All England Club but there are times when lawn tennis can still feel bruising and confrontational.
Jessica Pegula, the No.4 seed from the United States, whose parents are the owners of the Buffalo Bills NFL team, produced a great burst of intensity and aggression in the opening minutes of her all-American first round match against Lauren Davis.
On the first morning of The Championships, the grass courts are untouched, immaculate and almost impossibly green.
The No.2 Court lawn was clearly to Pegula's liking with the 29-year-old taking a 4-0 lead after 12 minutes.
Pegula thinks that the power in your game determines how you compete on grass and she was out-gunning Davis, her average service speed a good 7mph faster than her opponent's.
Although Pegula wasn't able to maintain that level - to play as supremely as the court looked - and she couldn't convert her three match points in the second-set tie-break, she held her nerve and advanced 6-2, 6-7(8), 6-3.
"I just kept my focus and didn't get too frustrated there," she told the No.2 Court crowd. "I like being first on," she added. "I like to know my fate right away."
As Pegula has acknowledged, she's not one of those underdog stories that tennis fans like "rooting for". After all, she's a top five player with wealthy parents.
But the American is worth following this Fortnight to see whether she can go deep into the Wimbledon draw for the first time, perhaps even live up to her seeding by making the semi-finals.
At every other Grand Slam apart from Wimbledon, Pegula has reached the quarter-finals but her best result to date at SW19 was reaching the third round here last summer.
Pegula's performances at Eastbourne last week - where she reached the quarter-finals, only to be beaten by her doubles partner Coco Gauff - demonstrated that she can play on grass.
Her tennis against Davis also suggested the same.
Pegula had some rough luck at the last Grand Slam, getting food poisoning just before Roland-Garros from escargots or possibly "a bad piece of fish" at her first dinner in Paris.
She was like a "zombie" for a couple of days, which must have contributed to her going out in the third round.
If Pegula can avoid a similar calamity in the restaurants of Wimbledon Village, she could put a run together this Fortnight.
Pegula will now meet world No.78 Cristina Bucsa, who beat world No.72 Kamilla Rakhimova, in the second round.
