NEW YORK — Minutes after the NBA draft started, Derrick Rose learned he was headed home. Long after it ended, O.J. Mayo and Kevin Love were on the move.

A night that began with the expected pick ended with a stunning trade, which had two top-five selections changing teams as part of an eight-player deal between Minnesota and Memphis.

The Timberwolves dealt the rights to Mayo, the No. 3 pick, to the Grizzlies for Love, taken two spots later, in a trade that wasn't completed until past 2 a.m., some two hours after Boston made the 60th and final pick of the draft.

Minnesota also received Mike Miller, Jason Collins and Brian Cardinal, and sent Antoine Walker, Marko Jaric and Greg Buckner to Memphis.

"We fully expected to have O.J. on our team next year," Minnesota assistant general manager Fred Hoiberg said. "This deal came up very late in the draft. We just felt this deal had too many pieces that addressed needs that we had that we just couldn't pass it up."

"Plans are on the fly in this business," Grizzlies GM Chris Wallace said. "We were hoping to get O.J., but awhile back it was obvious he was not going to drop to five."

Hours earlier, the Chicago Bulls selected Rose, who grew up on the city's South Side, with the No. 1 pick, choosing the Memphis guard over Kansas State forward Michael Beasley.

With Beasley going second to Miami and Mayo following, college freshmen made up the first three picks for the first time in draft history.

"We actually talked about this earlier," Beasley said. "We all grew up together and we all grew up playing against each other and we all made a pact together that we would all be here. Just to see it all fall into place and see it all happen is kind of crazy."

Five of the first seven players selected and 10 in the first round were freshmen, both NBA records. It was also a big night for the Pac-10 Conference, which had five of the first 11 picks.

Rose led the Tigers to the national championship game in his lone college season. The Bulls opted for the point guard's playmaking ability over the scoring and rebounding of Beasley, who ranked in the top three in the nation in both categories.

"We talked so much about it. We really did," Bulls general manager John Paxson said. "Very honestly, at the end when we made our decision, it was unanimous with my scouts and coaches and myself. This was the direction we wanted to go in the end, and it has nothing to do with the talent of Michael Beasley. This had everything to do with the direction we felt was right for us."

The 6-foot-3 Rose put on a red Bulls cap, hugged some supporters, including Memphis coach John Calipari, and shook hands with Beasley, seated at a nearby table, before walking onto the stage to meet NBA commissioner David Stern.

"I was a little nervous when they came back out, but I always had that in mind that I want to be No. 1," Rose said. "So it was great hearing my name and being the No. 1 pick."

Miami settled for Beasley, who wasn't sure if the Heat would go for Mayo instead. Beasley averaged 26.2 points, third in the nation, and topped Division I with 12.4 rebounds per game. But with questions about his size — he may be 2 inches shorter than the 6-foot-10 he's listed at — the Bulls may not have believed he could play the 4 spot in the NBA.

UCLA guard Russell Westbrook was the first nonfreshmen taken, going fourth to the Seattle SuperSonics — with new teammate and reigning Rookie of the Year Kevin Durant standing and applauding the pick from the back.
