Bynum is equal to challenge

The Big Teen took on Big Ben, and the results weren’t so bad for the Lakers’ 19-year-old center.

Andrew Bynum more than held his own Sunday against Chicago Bulls center Ben Wallace, the league’s four-time defensive player of the year.

Bynum’s on-the-fly education continued with 12 points, 13 rebounds and a career-best four blocked shots in 28 minutes. Wallace, known much more for his scowling, aggressive defensive posture than his scoring touch, had eight points, 12 rebounds and two blocks in 41 minutes.

Bynum fouled out with 4:15 to play, but there were moments to note before he left.

He blocked Wallace’s shot 22 seconds into the game and drew immediate approval from the crowd. Wallace got him back later in the first quarter, blocking his shot on an up-and-under move, but then Bynum pinned him down low for a four-foot hook shot midway through the second quarter.

Wallace blocked an attempted dunk by Bynum late in the third quarter, but the kid earned some respect from the veteran.

“He’s a young guy, a solid post player,” Wallace said. “He stays away from some of the things that he can’t do and he just does whatever he can do to help this team. That’s a sign of a great player to come, especially in this league.”

Before the game, Lakers Coach Phil Jackson said he didn’t expect too much from Bynum.

“We don’t anticipate that Andrew’s going to have a great deal of success against Ben,” he said. “Whatever we get from him is going to be gravy.”

Afterward, Jackson acknowledged being caught off guard.

“More than anything else, I was surprised at his tenacity and rebounding, his defensive ability out there,” he said. “That helped us out.”

Jordan Farmar sustained a moderately sprained right ankle after pulling up quickly with the ball with 3:32 left in the second quarter. He left the game for X-rays, which were negative.

“My crack training staff said that it’s not a serious ankle sprain,” Jackson said. “He should be OK in a matter of a day or two.”

Said Farmar: “Not the way it feels right now, but they know better than I do.”

If Farmar cannot play Tuesday against the Clippers, veteran Aaron McKie could be on the active roster for the first time this season.

McKie had a good training camp until he sustained a strained back during exhibition play. He has been practicing with the team and is cleared to play in games, but has not cracked the backcourt rotation.

Maurice Evans hit a rattle-around-the-rim three-pointer, leading to a possible new moniker from Kobe Bryant. “That was the second game in a row now where he’s made some ‘lotto’ shots. I’m going to start calling him ‘lotto.’ ” Evans finished with six points.... Japanese pitcher Daisuke Matsuzaka sat courtside for Sunday with his agent, Scott Boras.
