March Madness continues Saturday night when the Michigan State Spartans and the Duke Blue Devils battle in the Final Four.  The 2015 NCAA Tournament game tips off at 6:09 p.m. ET; links to the free live stream and the free radio broadcast are provided below.

No. 7 Michigan State's surprising run continued Sunday with a 76-70 win over Louisville.  Senior guard Travis Trice has been a huge part of the Spartans' success in the tournament, averaging 19.7 points through the team's first four games in the tournament.  While many have been shocked by what Michigan State has done so far in March, Trice and his teammates aren't surprised by the success they've had.

"We've been that way all year: overlooked, doubted the whole time," Trice said, according to the Associated Press.  "But we don't really look like it like that," Trice added, moments later. "If we win, people are going to be talking about us. We win a national championship, everybody will be talking."

For Spartans coach Tom Izzo, one challenge he faces is outcoaching Duke's Mike Krzyzewski, who's won eight of nine games against Izzo.  Krzyzewski, though, isn't looking at the numbers.

"You know, stats are unbelievable, man," Krzyzewski said. "That doesn't make a difference at all. They're going to be ready. You know what? They don't lack talent."

No. 1 Duke has lost only four games this season, and - with the exception of a close game against Utah in the fourth round - has been dominant in the tournament.  Krzyzewski earned his 12th trip to the Final Four with last weekend's 66-52 win over Gonzaga.

For Duke's freshman trio of Jahlil Okafor, Tyus Jones and Justise Winslow, it may be the only Final Four they ever play in.

"It's just special. You can just feel it in the air now, how important it is, what it means to be here," said Jones, one of Duke's three freshmen who may declare for the NBA after the season. "Just look out and see how many seats are out there. On Saturday night, those seats are all going to be filled. It's a special feeling."
