The Marlins and the Carnival Center have teamed up on a ticket promotion.

Baseball Hall of Famer Dave Winfield is the host and narrator of the Play Ball! The Baseball Music Project, which is a celebration of baseball through music, playing Friday at the Knight Concert Hall at the Carnival Center for the Performing Arts in Miami. Against a backdrop of baseball images and video, the Florida Classical Orchestra will play songs such as Take Me Out to the Ballgame, You’ve Gotta Have Heart and Joltin’ Joe DiMaggio.

The promotion allows patrons to buy tickets for $25 using the promotional code MARLINS789 and also get a ticket to a Marlins game for just a $1 service fee. Tickets from The Baseball Music Project can be turned in at Dolphin Stadium for Bullpen Box seats at any Sunday through Thursday home game this season.

And Winfield will be on hand at Saturday’s Marlins-San Diego Padres game at Dolphin Stadium to autograph copies of his new book Dropping the Ball – Baseball’s Troubles and How We Can and Must Solve Them to raise money for the Florida Marlins Community Foundation. Fans, who aren’t attending the Carnival Center show, can guarantee a chance to meet Winfield and get a signed copy of the book by visiting the Community Corner at the stadium during Friday night’s game and making a $25 donation.

SEVENTH HEAVEN

Taco Bell has another unusual baseball promotion. It’s offering fans a chance to post a marriage proposal on the virtual sign behind home plate during a nationally televised baseball game on Fox on July 7. The “official quick service restaurant” of Major League Baseball picked the date because it says it’s “considered by many as one of the luckiest and most romantic days of the century” because of its unique number sequence -- 07-07-07 -- and to promote its new 7-Layer Crunchwrap.

To enter Taco Bell’s “7 Layers of Love” contest, fans, who are at least 18, have until May 27 to submit “seven reasons why your significant other would be lucky to marry you” at www.tacobell.com. The entries will be narrowed to seven finalists and the winner will be determined in time for the game. The grand prize winner gets the virtual proposal and a year’s supply of Taco Bell food. For those who are wondering, that’s $500 in Taco Bell Bucks.
