Players to tweet fans during Derby

Want to let Jose Bautista or David Ortiz know how you felt about that blast they hit into the Chase Field seats in the Home Run Derby? Just tweet him.

The Toronto Blue Jays and Boston Red Sox sluggers are among a handful of players who have agreed to communicate with fans via Twitter from the field at Monday night’s festivities.

Others taking part include Heath Bell, Gio Gonzalez, Joel Hanrahan, Matt Kemp, Howie Kendrick, Hunter Pence, Brandon Phillips, Gaby Sanchez, Justin Upton, Shane Victorino and C.J. Wilson.

Bautista, Ortiz and Kemp are Home Run Derby participants. The others are schedule to play in Tuesday’s All-Star game, with the exception of Victorino, who has withdrawn due to injury.

The MLB says other players on hand Monday night will have the opportunity to provide live commentary, photos and video through the Twitter and Facebook accounts of Major League Baseball and the Major League Baseball Players Association.

GOLDEN HOMERS

A few of the balls used in Monday’s home run derby will have a little something extra for the fans who catch them: gold.

The special balls will be made with one panel that’s infused with 24-carat gold leather and will be used once a batter is down to his final out in each round of the derby.

The balls have a retail value of $149.99, so anyone who manages to snag one at Chase Field will get a little extra value for their effort. Major League Baseball, along with State Farm Insurance, also will donate a combined $18,000 to the Boys and Girls Clubs of America for each golden ball that goes out for a homer.

BERNIE PLAYS

Former New York Yankees outfielder Bernie Williams played the national anthem on his guitar before Sunday’s Futures Game.

Williams won four World Series titles and four Gold Gloves in 16 years with the Yankees and was an accomplished musician even during his playing days. He released his first album in 2003 and put out another in 2009 that was nominated for a Latin Grammy.

Williams, who last played in the majors in 2006, played a flawless rendition of the national anthem on Sunday, receiving a warm ovation.

COOLING TREND

While dashing from hotels to taxis to the enclosed air conditioned comfort of Chase Field, the All-Star experience for fans is a scorching one, but perhaps not as bad as had been forecast.

The temperature cooled to 102 degrees on Sunday afternoon and, thanks to the threat of thunderstorms, might not even reach triple digits on Monday. The forecast high for Tuesday, the date of the All-Star game, is a mere 101. The average high for this time of year is 107.

On July 2, the high in Phoenix hit an incredible 118, a record for that date. That was a dry heat, but then so is a blow torch. Then came the massive dust storm that sent a wall of dirt through the city, a spectacle widely displayed on video across the country.

The lower temperatures bring higher humidity, and still-miserable conditions. Paramedic units were deployed around the ballpark and the nearby FanFest to provide aid for anyone overcome by the heat.
