Bobby Bonilla Day: The story behind the best baseball contract ever

The most interesting holiday of America’s favorite pastime comes just three days before the country celebrates its independence.

On July 1 of every year from 2011 to 2035, the New York Mets have and will write a $1.19 million check to former player Bobby Bonilla — even though he hasn’t suited up for the team in the 21st century.

“We got a guaranteed 8% interest rate,” Dennis Gilbert, the sports agent who negotiated the contract for Bonilla, told Yahoo Finance (video above). “Made it work and gave him income all the way through age 65.”

The Bronx native will be paid in roughly $29.75 million over the course of the contract — and it all sprang from a $5.9 million salary owed to Bonilla for the 2000 season.

“No one really knew about it until it came news,” Bonilla told Yahoo Finance. “It was pretty funny that all of a sudden now it became this thing. Every time I look at Dennis, I say: ‘Thank you.’”

1999 was ‘probably the most difficult year’ for Bonilla

Roberto Martin Antonio Bonilla last stepped on the field wearing the Mets’ dark blue and orange colors in the last game of the 1999 regular season when he grounded out to Pittsburgh Pirates’ first baseman Kevin Young as a pinch hitter in the bottom of the ninth inning.

Following their expulsion from the postseason, the kings from Queens immediately went into restructuring the roster, starting with Bobby Bonilla. After all, in the 1999 season, the outfielder played 60 games and hit .160.

“Yeah, '99, which is probably the toughest year play. The one year I went back with the Mets, probably the most difficult year,” Bonilla said.

In his 16 years in the league with eight teams, Bobby Bo collected three-time Silver Slugger awards, six MLB All-Star selections, and a World Series ring with the 1997 Florida Marlins.

The Mets traded for Bonilla before the 1999 season from the Los Angeles Dodgers for relief pitcher Mel Rojas. The trade meant taking on the final two years of a $23.3 million contract that would have the boys from Flushing paying $5.9 million a year.

Bonilla made waves in 1999 — but mostly for his struggles on and off the field. He struggled to get on base and he fought with the press and Mets management, including namesake and manager at the time Bobby Valentine.

His most infamous moment during the season came in the sixth game of the NLCS match against the Braves when he was spotted playing cards in the clubhouse with future Hall of Famer and teammate Rickey Henderson.

How the famous contract came to be

The Mets had enough, and so they met up with Bonilla’s agent and agreed on a deal that would go down in the Hall of Fame of retirement plans.
