Bag of Jose Fernandez-signed baseballs washes up on Miami Beach

A bag of baseballs autographed by Miami Marlins pitcher Jose Fernandez, who died in a boating accident early Sunday morning, washed ashore on Miami Beach on Monday, according to law enforcement officials.

Ocean Rescue Division Chief Vincent Canosa told WSVN-TV in Miami that a black bag containing four signed baseballs apparently belonging to one of the three people who died in the accident was turned into a lifeguard at 24th Street -- approximately one mile from where the 32-foot boat was found upside down on a jetty off Miami Beach.

The 24-year-old Fernandez, Emilio Macias, 27, and Eduardo Rivero, 25, all died in the accident.

The discovery was made on the day that the Marlins returned to the field with everybody wearing Fernandez's No. 16 jerseys, and second baseman Dee Gordon highlighting the emotional day by hitting his first home run of the season and fighting back tears as he crossed home plate.

Fernandez was 16-8 with a 2.86 ERA this season, earning his second appearance in the All-Star Game. Fernandez, who was named the National League Rookie of the Year in 2013, was 38-17 with a 2.58 ERA in 76 career starts for the Marlins.

Fans established a makeshift memorial on the plaza outside the ballpark entrance, leaving dozens of flower arrangements -- daisies, carnations, roses and lilies, the result as colorful as Fernandez's personality. There were also candles, and messages scrawled on balls, balloons, photos and jerseys.

"It's our job to make his life matter, so we're going to do that forever, and forever starts today," Marlins president David Samson said Monday.
