Red Sox announce $52M, six-year Matsuzaka deal

Matsuzaka said he had toured Fenway Park -- a place he'd seen several times on television -- and saw ongoing renovations before his news conference.

"Very beautiful and very impressed," he said.

The team's newest pitcher threw off the mound to Henry, with the soft toss sailing over his head. The owner fell backward before propping himself with both hands on the ground behind him.

"We didn't go over signals," Henry joked.

The bleacher fans no doubt will hang "K" placards from the green wall behind them every time Matsuzaka -- whose first name is pronounced "Dice-K" -- records another strikeout. In eight pro seasons, all with Seibu, he has 1,355 strikeouts in 1,402 1/3 innings.

"Matsuzaka called me after his press conference to thank me and he sounded very happy," Seibu acting president Hidekazu Ota said. "I wish him and his family all the best."

Matsuzaka was in the spotlight in 1998 when he led Yokohama High School to the Koshien Tournament championship. He pitched in the 2000 and 2004 Olympics and was most valuable player last March in the inaugural World Baseball Classic, won by Japan.

Matsuzaka passed a physical at Massachusetts General Hospital on Wednesday night. Minutes after Thursday's news conference, his deal was finalized when the terms were confirmed by the commissioner's office and the players' association.

"There were certainly a lot of ups and downs" during the negotiations Epstein said. "I think all the parties had a common goal which was for Daisuke to join the Red Sox and start his major-league career."

Epstein and Boras said the turning point came when Matsuzaka was satisfied that his wife and daughter would be taken care of during the transition to a new country.

"In any negotiation, there's a time limit," Boras said. "You make decisions and reach decisions based upon (the fact) you're forced to and the time frame for doing that obviously was escalated."

Had an agreement not been reached by midnight ET Thursday, 30 days after the Red Sox won the bidding, Matsuzaka would return to Japan and they would have kept their money.

Matsuzaka has a 108-60 record in Japan with a 2.95 ERA and 1,355 strikeouts in 204 games.

He gets a $2 million signing bonus payable upon approval of the contract, $6 million next year, $8 million in each of the following three seasons and $10 million in each of the final two years.

Epstein wouldn't say if Boston has baseball's best starting staff, but Red Sox chairman and owner Tom Werner wasn't shy about doing that.

"We've certainly had some exciting days at Fenway Park in the past few years," he said, "but the excitement at Fenway Park in 2007 will really be ratcheted up another notch."
