Johnson -- no stranger to the Big Apple as he began his managerial career with seven seasons with the Mets, and won the World Series with New York in 1986 -- spent the early part of his day helping bond-trading firm Cantor Fitzgerald with its annual charity day in Manhattan.
More than 100 celebrities and athletes -- including Johnson, who said he enjoyed time alongside New York Giants quarterback Eli Manning and New York Jets quarterback Mark Sanchez -- "traded" bonds, with 100 percent of the global profits being donated to charity. The fundraiser commemorates the 658 Cantor Fitzgerald employees lost in the 2001 attacks.
"It's just a great cause for all the heroes and people who died, to give something back," Johnson said. "I certainly love the city of New York and how they're dealing with that loss. It's good to remember it. There were a ton of people in the Financial District going by the site, and it was nice to be there."
The Nationals wore their navy blue Stars and Stripes uniforms on the road for the first time Tuesday, while the Mets wore hats during batting practice and the national anthem to honor New York first responders. The hats will be autographed and auctioned off with proceeds distributed by the Mets Foundation to Sept. 11-related organizations.
Representatives from the NYPD, FDNY, PAPD, EMS Court Officers, OEM and the Sanitation Department presented the colors before the game. Juliette Candela (from the 9/11-related organization Tuesday's Children) sang the national anthem, while Regina Wilson (FDNY) performed "God Bless America."
