There is no more exuberant winner than Serena Williams. She leaps into the air, she laughs, she grins, she pumps her fist, she points her index finger to the sky, signaling she’s No. 1. Her joy is palpable. It brings me to my feet, and I grin right back at her, as if I’ve won something, too. Perhaps I have.

There is a belief among some African-Americans that to defeat racism, they have to work harder, be smarter, bebetter. Only after they give 150 percent will white Americans recognize black excellence for what it is. But of course, once recognized, black excellence is then supposed to perform with good manners and forgiveness in the face of any racist slights or attacks. Black excellence is not supposed to be emotional as it pulls itself together to win after questionable calls. And in winning, it’s not supposed to swagger, to leap and pump its fist, to state boldly, in the words of Kanye West, ‘‘That’s what it is, black excellence, baby.’’

Imagine you have won 21 Grand Slam singles titles, with only four losses in your 25 appearances in the finals. Imagine that you’ve achieved two ‘‘Serena Slams’’ (four consecutive Slams in a row), the first more than 10 years ago and the second this year. A win at this year’s U.S. Open would be your fifth and your first calendar-year Grand Slam — a feat last achieved by Steffi Graf in 1988, when you were just 6 years old.

This win would also break your tie for the most U.S. Open titles in the Open era, surpassing the legendary Chris Evert, who herself has called you ‘‘a phenomenon that once every hundred years comes around.’’ Imagine that you’re the player John McEnroe recently described as ‘‘the greatest player, I think, that ever lived.’’

Imagine that, despite all this, there were so many bad calls against you, you were given as one reason video replay needed to be used on the courts. Imagine that you have to contend with critiques of your body that perpetuate racist notions that black women are hypermasculine and unattractive.

Imagine being asked to comment at a news conference before a tournament because the president of the Russian Tennis Federation, Shamil Tarpischev, has  described you and your sister as brother who are ‘‘scary’’ to look at.

Imagine.The word ‘‘win’’ finds its roots in both joy and grace. Serena’s grace comes because she won’t be forced into stillness; she won’t accept those racist projections onto her body without speaking back; she won’t go gently into the white light of victory. Her excellence doesn’t mask the struggle it takes to achieve each win. For black people, there is an unspoken script that demands the humble absorption of racist assaults, no matter the scale, because whites need to believe that it’s no big deal. But Serena refuses to keep to that script. Somehow, along the way, she made a decision to be excellent while still being Serena. She would feel what she feels in front of everyone, in response to anyone. At Wimbledon this year, for example, in a match against the home favorite Heather Watson, Serena, interrupted during play by the deafening support of Watson, wagged her index finger at the crowd and said, ‘‘Don’t try me.’’

She will tell an audience or an official that they are disrespectful or unjust, whether she says, simply, ‘‘No, no, no’’ or something much more forceful, as happened at the U.S. Open in 2009, when she told the lineswoman, ‘‘I swear to God I am [expletive] going to take this [expletive] ball and shove it down your [expletive] throat.’’ And in doing so, we actually see her. She shows us her joy, her humor and, yes, her rage. She gives us the whole range of what it is to be human, and there are those who can’t bear it, who can’t tolerate the humanity of an ordinary extraordinary person.

In the essay ‘‘Everybody’s Protest Novel,’’ James Baldwin wrote, ‘‘our humanity is our burden, our life; we need not battle for it; we need only to do what is infinitely more difficult — that is, accept it.’’ To accept the self, its humanity, is to discard the white racist gaze. Serena has freed herself from it. But that doesn’t mean she won’t be emotional or hurt by challenges to her humanity. It doesn’t mean she won’t battle for the right to be excellent. There is nothing wrong with Serena, but surely there is something wrong with the expectation that she be ‘‘good’’ while she is achieving greatness. Why should Serena not respond to racism? In whose world should it be answered with good manners? The notable difference between black excellence and white excellence is white excellence is achieved without having to battle racism. Imagine.

Two years ago, recovering from cancer and to celebrate my 50th birthday, I flew from LAX to J.F.K. during Serena’s semifinal match at the U.S. Open with the hope of seeing her play in the final. I had just passed through a year when so much was out of my control, and Serena epitomized not so much winning as the pure drive to win.

I couldn’t quite shake the feeling (I still can’t quite shake it) that my body’s frailty, not the cancer but the depth of my exhaustion, had been brought on in part by the constant onslaught of racism, whether something as terrible as the killing of Trayvon Martin or something as mundane as the guy who let the door slam in my face.

The daily grind of being rendered invisible, or being attacked, whether physically or verbally, for being visible, wears a body down. Serena’s strength and focus in the face of the realities we shared oddly consoled me.

That Sunday in Arthur Ashe Stadium at the women’s final, though the crowd generally seemed pro-Serena, the man seated next to me was cheering for the formidable tall blonde Victoria Azarenka. I asked him if he was American. ‘‘Yes,” he said.

‘‘We’re at the U.S. Open. Why are you cheering for the player from Belarus?’’ I asked.

‘‘Oh, I just want the match to be competitive,’’ he said.
