MLB All-Star FanFest Attractions Slideshow

World's Largest Baseball

According to All-Star FanFest, this white leather, red-laced ball is the largest baseball in the world. The sphere measures 12 feet in diameter. It boasts signatures from Hank Aaron, Rod Carew, Derek Jeter, Ozzie Smith and other baseball greats. More signatures are expected to be written on the ball before the All-Star Game.

Mets Team Photo Cut-Out

It may not be the '69 or '86 Mets, but this year's team includes a roster that has gained respectability in recent weeks. Place yourself in the team photo by standing next to your favorite Met, such as 2013 MLB All-Star Summer Ambassador David Wright. It is part of the "Hometown Heroes" section.

Negro Leagues

New York City is home to the breaking of the baseball color barrier, as Jackie Robinson made his debut for the Brooklyn Dodgers in 1947. MLB fans may not know that other MLB Hall of Famers such as Willie Mays, Hank Aaron and Ernie Banks all played in the Negro leagues. The Negro leagues museum includes game-worn jerseys and the above cut-out of a group of Homestead Grays (the legendary James "Cool Papa" Bell is crouching all the way to the right).

Charles Fazzino's Art

Artist Charles Fazzino, a New York native known for his 3D pop art style, was tabbed to design a series of All-Star game-themed pieces. The above piece is a baseball with references to historical Mets moments such as the 1969 World Series championship, Bill Buckner's error in the 1986 World Series and Endy Chavez's catch in the 2006 NLCS. The piece is listed at $45,000.

Live and Silent Auction

The live and silent auctions feature a variety of rare sports memorabilia that includes vehicles. The white Harley-Davidson motor scooter above was used by Warren Spahn in the 1960s and is listed between $5,000 and $10,000. The brown motorcycle is custom-designed by Ken Griffey, Jr. and Nick Anglada Originals, Inc. It is signed on the fender by Griffey, Jr. and it has two glass cases with balls signed by Willie Mays, Hank Aaron, Jim Thome, Alex Rodriguez, Sammy Sosa, Barry Bonds and Babe Ruth. It is listed between $25,000 and $50,000, and it will help raise funds for the Florida Hospital Foundation.

The Minor Leagues

The Minor Leagues Corner features the above map of every minor league affiliate of the MLB. There is also a wall of minor league hats, donning 160 caps.

Collector's Showcase

The globe's greatest baseball collectors convene every year at All-Star FanFest to display and sell their prized possession. None may be as unique as the Joe DiMaggio statue priced at $5,000 by Jim Maser, a.k.a. "The Pin Man." According to his brother, Dave, Maser has one of three of the sculptures in existence. The other two are owned by the DiMaggio family and sculptor Peter Rubino. The Babe Ruth sculpture to the left is also a Rubino piece.

MLB Trophies

The Commissioner's Trophy, the apex of Major League Baseball given to the World Series Champion, is currently located at the Javits Center. Not as protected as the Stanley Cup, visitors can walk right up to the trophy. Other trophies on display include the MVP Award, the World Series MVP Award, the Rookie of the Year Award and the All-Star Game MVP Award.

Performance Center

Presented by Under Armour, the Performance Center tests the precision of one's baseball skills. Guests can try to throw a strike to Buster Posey (sort of), time their steal speed from first base to second base or make a diving catch into a matt. The venue's wall includes the cleats of Clayton Kershaw, Ryan Howard, Bryce Harper, Manny Machado, Jose Reyes and other MLB stars.

Fields of Play

Ever wonder what it would be like to take the field in the top of the first inning in front of the home crowd? The emotional experience may only be for the players, but thanks to Scotts, fans can feel the grass their heroes field on. The above grass is Kentucky bluegrass from Wrigley Field (the actual field, not the ivy on the wall).

National Baseball Hall of Fame & Museum

The National Baseball Hall of Fame & Museum brought all kinds of goodies from Cooperstown including Mets gear, such as Gil Hodges 1969 World Series jersey and John Franco's post-9/11 FDNY hat, and historic jerseys, such as Chick Hafey's 1933 All-Star Game jersey (Hafey earned the All-Star Game's first hit in the inaugural 1933 game). A total of 83 artifacts were brought from Cooperstown. Notice the above sign on the exhibit's stage does not have a player on it.

Fast Relief Pitch

What baseball festival would be complete without a fast pitch station? Test your fastball's speed (but stretch first).

Tire Tryout

The Tire Tryout is all about precision. Either throw a baseball through a tire like the traditional quarterback drill or bunt for a hit.

Video Game Zone

Test your virtual home run hitting ability on MLB The Show 13. The top home run hitters at FanFest will earn a chance to compete on the jumbotron at Citi Field during the All-Star Game.

Rookie Leagues

The ultimate kids venue at FanFest, Rookie Leauges includes the T-ball home run derby setup above. There is also a T-ball cage, a throwing cage, a target practice station and a stealing home plate race. After going through the drills, what better way to finish than face painting?

Yogi Berra Museum & Learning Center

Learn all about the man with the most World Series championships (10) in MLB history and his nonprofit organization. Also, check it out some cool Yogi gear, including the jersey and bathrobe (with a No. 8 on the back) in the background.

Women On The Diamond

A League of Their Own comes to life, as jerseys from the All-American Girls Professional Baseball League are displayed. The above jersey is that of the Kenosha Comets. Former players from the league are available at certain times for autograph sessions.

The Diamond

The 10,500-square foot diamond presented by T-Mobile centers FanFest and is the stomping grounds for many of the event's famous guests. In this picture, taken from the MasterCard Priceless New York Rooftop, a group of mascots are participating in a home run derby.
