Originally frontloaded to the spring, Jordin Sparks‘ tour calendar recently underwent a major overhaul.

More than a dozen concerts from her Battlefield Tour itinerary have been rescheduled for summer or cancelled outright, and several others are still awaiting a final decision.

The tour will not officially launch until June 1, though some spring performances remain on the books. At the moment, the summer trek’s first confirmed event is a rescheduled June 3 show at Starland Ballroom in Sayreville, NJ.

An April 23 show at Newport Music Hall in Columbus, OH, which would have launched the tour, is now cancelled. According to that venue promoter’s official Web site, refunds will be available from the original point of purchase through May 1. Also axed from the calendar is a May 6 performance at Main Street Armory in Rochester, NY.

Most other concerts booked for April and May have been shifted to new dates later in the summer. But rescheduled dates are still forthcoming for postponed gigs on May 9 at First Avenue in Minneapolis, MN; May 13 at the House of Blues in Chicago, IL; and May 15 at The Pageant in St. Louis, MO.

The updated Battlefield Tour itinerary is listed below. Concert-goers are advised to hold onto their tickets for the original performances as they will be honored on the rescheduled dates, in most cases.

According to Spark’s official Web site, the changes are the result of “an effort to bring [the tour] to more cities throughout the country.” More tour dates are expected in the near future, with the summer 2010 routing eventually hitting about 35 national markets.
