In the final minute of an N.B.A. playoff game on Monday night, Doug Christie raised his left fist, extending his pinkie and index fingers toward the rafters of Arco Arena. Christie, a lanky swingman for the Sacramento Kings, appeared to be calling out a play for his teammates.
But the message was actually intended for his wife, Jackie, seated in the stands. He often makes the same hand signal at least 50 times a game.
''That's just to let my wife know I love her, and she and family are bigger than basketball,'' Christie said.
Jackie Christie said she and her husband began communicating with each other during games a while ago. ''When I make this sign, it means drive to the hole,'' she said. ''When I make this sign, it means smile because you look a little sad on the bench. He started making this sign and said, 'This means I love you,' and it developed from there. It makes me feel real special.''
Reporters who cover Christie's former team, the Toronto Raptors, were so intrigued by the couple's sign language that they created a betting pool when the Raptors played at Sacramento last November. By their count, Christie signaled his wife 62 times during the game.
''Sixty-two,'' Jackie said, shaking her head in a pleased manner recently as she clutched her husband's hand on the couch in their home in suburban Sacramento. ''That's beautiful.''
When the Kings flew to Los Angeles today for Game 3 of the Western Conference finals against the Lakers on Friday night, Jackie was seated next to Doug, as much a part of the postseason experience as any family member in the N.B.A.
In the frenetic world of major professional sports, where athletes have trouble balancing their personal and public lives -- and the perception of don't-ask, don't-tell marriages is sometimes a reality -- the Christies have gone to great lengths to make sure their own vows are kept sacred.
With few exceptions, Doug Christie does not look at other women, avoiding dialogue or even eye contact. ''Every conversation I've ever had with a woman since we've been married besides my wife she knows about,'' he said. ''She's been there. But what are we talking about? Banking? Mortgage? Other than that, I don't have anything to say to anybody. It's taking up my time and my time is limited to basketball and my family.''
The Christies, who have been married for eight years and have three children, get married on July 8 each year, their anniversary. It is not a mere renewal of their wedding vows, but an actual wedding -- replete with friends, family, cake and a reception.
This year, they will be married on the foundation of their new, not-yet-completed home in Bellevue, Wash. Christie's agent, Bradley Marshall, who is also a minister, has married them the past two years.
''At first I thought this was a little bit much, but when you see the dividends it pays, you understand,'' Marshall said. ''They invite other married couples to the wedding, and they're very encouraged by the whole process. It's very emotional.''
Jackie said she attends 25 to 30 of the Kings' 41 regular-season road games, riding on the team's charter.
''I used to tell people I was married to an athlete and they would give me that look, 'Oh, we know what he's doing,' '' she said. ''I don't try to explain anymore: 'Yeah, but he's different. And I travel with him and he's not like the rest.' I just know Doug is faithful.''
When Christie played for the Raptors, his wife once confronted a female fan seeking an autograph and a kiss in Toronto. ''A security guard grabbed her, but I put my hand up and told her to back off really loud,'' she said. ''It scared me, because my voice sounded like a demon. It just came out. She was a pretty girl, very young. But she was touching someone she shouldn't have been.''
Some wives of professional athletes focus on the perks of life in the big time: affluence, public attention, premium seats at sold-out games. Jackie Christie sees a different reality, one in which her husband and other players are battling the seduction of women who wait after games and prowl hotel lobbies.
''You see so much of that going on, you think, 'Is that going to happen to me?' '' she said. ''I'm fine now. I gave up trying to change things. People are going to be the way they're going to be. Now, my attitude is, whatever we have to do to keep our circle tight. Just respect what we have and our commitment.''
Sustaining relationships can be difficult for N.B.A. players, said Charles Smith, a former player who was a union vice president. ''Nine times out of 10, when a player gets married early in his career, he's still growing and his spouse is still growing,'' Smith said. ''Then you have kids, and it's a very difficult juggling act. If you don't have a firm foundation to fall back on, it doesn't work.''
Rick Fox, the Lakers' forward, and his wife of three years, the actress and singer Vanessa Williams, sometimes put up with a bicoastal relationship. Williams is starring on Broadway in ''Into the Woods.''
