Sacramento, Calif. (NBA.com exclusive) --  Kevin Martin has been here before.

Last season, the wiry scorer was knighted the future star of the Kings. Then, he led the Kings to their first win of the season in the team's home opener against Memphis.

A season later, with another young, winless team on his shoulders, he did it again. This time, Martin scored 48 points to lead Sacramento to a 127-116 overtime win over the Grizzlies.

"We always go on the road and struggle for many reasons, but we always find a way to come back home and win," Martin said. "There's something about being at home."

After forcing bad shots early, Martin began to find his flow within the offense in the second quarter. Playing his most efficient game of the season, the fifth-year shooting guard shot 14 of 27, including a career-best seven 3-pointers.

Martin hesitated to call Monday night a must-win, opting instead to call it a "much-needed" win. "We'll take all the wins we can get."

Memphis jumped out to an early 17-4 lead, as the Memphis frontcourt of Marc Gasol, Zach Randolph and Rudy Gay dominated the lane. The Grizzlies scored 20 of their 33 points in the paint in the quarter.

But third-year big man Spencer Hawes made an immediate impact off the Sacramento's bench. An inadvertent, yet emblematic smack to the chest of Randolph while fighting for post position proved the Kings wouldn't lay down in the paint.

Hawes was physical inside and helped move the ball well for the Kings, finishing with 21 points, 11 rebounds and seven assists and two blocks.

"Spencer showed why everyone thinks he can be such a good player," coach Paul Westphal said. "It wasn't his skills, it was his heart he showed tonight.

"We have to fight and scratch and have that be our trademark. He showed he is capable of that tonight."

Sacramento took a three-point lead with less than a minute to play on a Hawes midrange jumper with 45.3 seconds left. The big man delivered an emphatic message to his teammates after the shot, screaming: "Let's finish this!"

With 36.9 seconds remaining, Gay had other plans, though. He hit a 3-pointer from the baseline to tie the game and following an Omri Casspi turnover, Memphis took the lead on a Randolph jumper with 6.1 seconds left.

But Beno Udrih, who delivered an unexpected effort from the Kings bench, scored on a layup with 1.4 seconds left to send the game to overtime. From there, the Kings took over behind Martin, Omri Casspi and Andres Nocioni, who combined to score all 17 of Sacramento's points in overtime.

Kings first-round pick and starting point guard Tyreke Evans, who played despite an ankle injury, was limited to just three points. Udrih came through down the stretch, finishing with 16 points and six assists.

The rookie Casspi, Israel's first NBA player, is already a fan favorite in Sacramento. With a pair of fans waving an Israeli flag courtside and his father in attendance, Casspi displayed marksmanship from the 3-point line (3-of-4) and quickness inside as he finished with 15 points off the bench.

"It was the first time my Dad has seen me play in the NBA," Casspi said. "During the game I just looked at him and saw him smile. It just made my dream and obviously it is his dream too."

Allen Iverson made the announcement this morning on his Twitter page that he would make his Grizzlies debut. Iverson missed Memphis' first two games of the season and all of the preseason after partially tearing his left hamstring.

Memphis coach Lionel Hollins said before the game that he was simply looking to see where Iverson was in his ability to step in and help the team.

"In this situation we are trying to win the game but we also want to get him back and fit him in," Hollins said. "But we're not going to jeopardize the game for that."

The 34-year-old veteran came off the bench and did show flashes of the scorer he is known as, scoring 11 points on 5-of-9 shooting. He also showed some signs of rust early and never found his flow in the game.

At one point in the fourth quarter, he was quickly replaced by starting point guard Mike Conley after he passed up a jumper that led to a three-second violation.

"I've been playing basketball 26 years," Iverson said. "It's like riding a bike. That's what I do. I'm a professional at it. I felt like me out there."

Randolph had 30 points and 16 rebounds before fouling out in overtime.

"I think we gave ourselves a chance to win," Randolph said. "We have to clamp down. Once we get a team on their heels, we have to learn how to put them away. This is a game we definitely should have won."
