D’Alessandro joins Red Sox partners

Boston — David D’Alessandro, the chairman of John Hancock Financial Services Inc., become a part-owner of the Boston Red Sox Saturday.

“They are a vibrant part of our community not only as a baseball team, but as a community citizen, too,” D’Alessandro said in a statement. “I hope that I can, in some small way, contribute to their success.”

In addition to John Henry, chairman Tom Werner and president Larry Lucchino, Boston’s ownership group has 16 limited partners.

D’Alessandro has been a critic in recent months of the U.S. Olympic Committee.

In January, he demanded the USOC provide a financial report, saying John Hancock might invoke a morals clause to pull out of its sponsorship deal.

The turbulent times at the USOC culminated in the resignation last month of its chief executive, Lloyd Ward.

D’Alessandro has said that the “financial improprieties, questionable business practices and perpetual instability” at the USOC are damaging the Olympic image.

Mets’ Vaughn leaves because of hip injury

New York — Mo Vaughn left the New York Mets’ game Saturday against Montreal after three innings with a hip injury.

Vaughn hit a sacrifice fly in the third inning, then was replaced by Jay Bell at first base in the fourth.

“I just tweaked it,” Vaughn said. “I didn’t want to do any more damage. I should be back in the lineup tomorrow.”

Vaughn has a minor strain to his right hip flexor.

“It stared tightening up on him,” manager Art Howe said. “We’ll see how he feels when he comes in tomorrow.”

The Mets beat Montreal, 3-1.
