PHOENIX -- Five-time All-Star Matt Williams, who had been the last of the original Diamondbacks until recently being released, announced his retirement yesterday. Williams, who had 378 career home runs, spent the past five seasons with the Diamondbacks. Though he still had a year on his contract, he was designated for assignment by the team June 1.

His agent, Joe Longo, said Williams talked to several teams but ultimately decided to stay home with his family.

"It was more a matter of his family. He put his family first," Longo said.

Williams, 37, had been leaning toward retiring after his contract with Arizona expired. His release accelerated the decision.

"He's newly engaged and he has his kids there. All things considered, he just didn't want to leave," Longo said.

The Diamondbacks tried to trade Williams and two others to the Colorado Rockies for Larry Walker in the off-season, but Williams and Walker rejected the deal.
