EAST LANSING, Michigan (Ticker) -- It has taken nearly four full seasons for Alan Anderson to shift his game into overdrive.
Anderson scored 22 points, grabbed 10 rebounds and led four players in double figures as No. 12 Michigan State posted a 90-64 victory over Penn State in a Big Ten Conference matchup.
The Spartans (22-5, 13-3 Big Ten), who will be the number two seed in the upcoming conference tournament, won their eighth game in nine outings and defeated the Nittany Lions for the sixth consecutive time.
Anderson recorded his second double-double of the season and has topped 20 points in three of his last four games after going 116 consecutive games without scoring 20.
"It's my second or third (double-double) and it feels great," Anderson said. "I was just being aggressive on the boards offensively and defensively."
"Alan has been playing unbelievable basketball for us," Spartans guard Chris Hill said. "Not just scoring, but he's been rebounding and he's been leading. He's been doing things we really needed from him."
Penn State (7-22, 1-15) tried to spoil Senior Night by using a 16-4 run, highlighted by eight points by Ben Luber, to take a 20-12 lead in the first 7 1/2 minutes.
But Michigan State picked up the pace and made four consecutive 3-pointers, including a pair by Maurice Ager in a 14-2 burst, which helped give the Spartans a 39-35 edge at halftime.
Anderson and Hill combined for 12 points as the Spartans opened the second half with a 14-2 burst to extend the margin to 53-37 with 15 minutes to play. Michigan State outscored Penn State, 39-9, in the first 14 1/2 minutes of the second half.
"We wanted to shoot better from three-point line," Michigan State coach Tom Izzo said. "The big one was making sure we limited their offensive rebounding and to hold them to only seven while we got 16 is big. We had 28 assists on 36 baskets, so that was impressive."
Hill scored 21 points, while Ager and Kelvin Torbert added 11 apiece for Michigan State, which made 13-of-26 3-pointers and has won 99 of 106 games at the Breslin Center.
The Spartans shot 55 percent (21-of-38) from the floor in the second half, forced 23 turnovers for the game and outrebounded the Nittany Lions, 37-28.
Luber and Mike Walker scored 12 points each for Penn State, which has lost 11 straight games and has dropped all 14 contests against the Spartans at East Lansing.
"Michigan State is very, very good in transition," Penn State coach Ed DeChellis said. "So you can't give them easy transitions. But there is no defense in the backcourt when (they take) it down the floor and that's something that has haunted us all year. In the second half, they really turned the heat up on us and we didn't handle the pressure very well."
