Indianapolis ? Baylor now has a basketball team it can celebrate. And oh, what a celebration it was.

The Lady Bears hugged, flopped on the floor in giddy delight and embraced their coach as a rainbow of neon-colored confetti rained down on the RCA dome.

All they had wanted was to be a shining light for a university stained by scandal.

One dazzling national championship ought to do.

Sophia Young’s 26 points, Emily Niemann’s precise three-point shooting and the brilliant, energetic play of the backcourt carried Baylor to an 84-62 victory over Michigan State on Tuesday night for the school’s first NCAA title by a women’s team.

“What a team I get to coach!” coach Kim Mulkey-Robertson said. “It wasn’t the coaching, it’s these guys taking me for a tremendous ride.”

And it was a fast one.

Five years after Mulkey-Robertson took over a team that went 7-20 and finished last in the Big 12 Conference, the Lady Bears were pulling on championship hats after a run through the tournament that included three victories over No. 1 seeds: North Carolina, LSU and finally the Spartans.

Both teams were playing in the finals for the first time. The margin was the second-largest in a championship game, falling one point short of the record set in 1987 when Tennessee beat Louisiana Tech, 67-44.

When the horn sounded Tuesday night, the players jumped in unison amid the streamers and screamed “We won! We won!” as fans chanted “Mul-key! Mul-key!” — a tribute to a coach who had taken the program to heights never before imagined.

“She doesn’t accept anything but the best from her players,” Baylor’s Steffanie Blackmon said. “She’s just hard on you, but it pays off, ’cause hey, we’re here, and we won the big thing right now.”

They did it with unforgiving defense that disrupted almost everything Michigan State tried, and by poking enough holes in the Spartans’ matchup zone to stay comfortably ahead after zooming to a 19-point lead in the first half. Niemann keyed the early surge and finished the first half with 15 points on 5-of-7 shooting from behind the three-point line; she finished with 19.

“I think (Niemann) was the whole key to this game,” Michigan State coach Joanne P. McCallie said. “If you take 51 off the floor, it was a different game. She was definitely the X-factor.”

Not that the Lady Bears were resting easy after that. Knowing that Michigan State had rallied from 16 down to beat Tennessee two nights before, Baylor kept attacking, making steals and scrambling for loose balls.

Their killer instinct was a perfect reflection of their feisty coach, who practically glowed in a bold aqua-blue pant suit as she stormed back and forth in front of the bench, calling plays, pleading for calls from the officials and cajoling her players to keep pressing — even with a 20-point lead.

They responded.

Young was unstoppable in the second half, scoring 18 points. The 6-foot-1 junior, who came to the United States from the West Indies at age 15 and had never played basketball before that, was named the most outstanding player of the Final Four.

“Well, all those moments all just paid off right now,” Young said. “This is what I came here for and I’m living my dream.”

Young went 10-for-19 from the field, grabbed nine rebounds and had four assists. Blackmon helped out with 14 points in the second half to finish with 22.
