Seattle ? Great week to be Ichiro Suzuki.

The Seattle leadoff man signed a $90 million, five-year contract extension Friday, three days after he was the unanimous MVP of the All-Star game. The deal ensures Seattle, enjoying its best season in four years, will not lose its franchise cornerstone to free agency this fall. Instead, the Mariners will keep the seven-time All-Star and perennial Gold Glove outfielder under contract until age 39.

“Now, I have the opportunity to be on one team for a long time. And I am grateful for that,” Suzuki said at a press conference announcing the richest contract in Mariners history.

“I’m going to do my best to play 10 more years here.”

Suzuki led the majors with 128 hits going into Friday night’s game against Detroit. He was batting .355 with five home runs and 39 RBIs, and had stolen 23 bases.

“We’ve signed a Hall of Fame-type player,” general manager Bill Bavasi said.

The contract contains base salaries of $17 million for each season from 2008-2012. Suzuki also gets a $5 million signing bonus, as well as deferred money.

“The one thing we have made clear since spring training was that it was our goal to have Ichiro play his entire career in Seattle, retire as a Mariner and go into the Hall of Fame in our cap,” Bavasi said.
