The competition may be over for sixth season “American Idol” winner Jordin Sparks, but her R&B battle rages on this spring with a fresh headline tour. The Battlefield Tour begins on April 23 at Newport Music Hall in Columbus, OH, and concludes May 23 at The Grove in Anaheim, CA.

A total of 22 concerts are scheduled for that four-week period, though additional tour stops are also planned for later in the summer. Sparks will reappear for a June 26 show at Dixie Landin’ in Baton Rouge, LA, and an August 8 event at the Wisconsin State Fair in West Allis, WI.

Highlights on the spring calendar include engagements on April 27 at the Nokia Theatre in New York, NY; May 2 at Hersheypark Amphitheatre in Hershey, PA; May 13 at the House of Blues in Chicago, IL; and May 22 at Club Nokia in Los Angeles, CA.

Tickets for some concerts are already available to the public, but another round of general onsales is planned for the March 26-28 weekend. Markets with imminent onsales include Houston and Dallas (March 26), Boston and Los Angeles (March 27), and Westbury (March 28).

The face value of tickets varies from market to market, but three of Sparks’ upcoming events are marked as free on her official fan club, Sparkstown. Amusement park concerts at Hersheypark and Dixie Landin’ are free with admission. Her May 1 performance at Connecticut casino Mohegan Sun is also listed as a free show.

Sparks is still promoting her sophomore effort, “Battlefield,” released in July 2009. The record debuted at No. 7 on the Billboard 200, three positions above her 2007 self-titled debut.

This is the most recent national tour for the “Idol” singer. Sparks spent most of last summer supporting Jonas Brothers on tour, as well as opening for Britney Spears’ second tour leg.
