A league of their ownNot many musicians can fill major league ballparks nowadays, but here's a look at who has rounded the bases of late:

Bruce Springsteen & E Street Band: The Boss is gearing up for a Sept. 7-8 stand at Chicago's Wrigley Field, as well as multiple nights at Mets, Red Sox and Nationals ballparks through fall.

Roger Waters and Brad Paisley: The Pink Floyd legend and country star played the first-ever concerts at Wrigley on back-to-back nights last month. Waters is also at Yankee Stadium this weekend.

Paul McCartney: The ballpark vet, at right, played the first show at the new Yankee Stadium last year as well as several other parks. Target Field nearly had him booked, but struck out.

Chesney & McGraw: The only other two ballparks on their tour are next weekend in Anaheim and Oakland, Calif. Their other 16 dates are in football stadiums (where all of U2's recent U.S. 360° Tour also played).

Sunday's concert lineupTickets: The show, initially declared a sell-out, had new tickets released and available as of Friday in the Sandbar general-admission section ($278) or in seated sections to the side of the stage ($78-$108) via Tickets.com.

Tentative set times: Jake Owen kicks things off at 4:30 p.m., followed by Grace Potter & the Nocturnals at 5:30, Tim McGraw at 6:30 and Kenny Chesney at 8:30.

No-nos: No blankets, lawn chairs, outside food or drink allowed. Also, smoking is not allowed inside the ballpark (and there will be no ins/outs).

VIP treatment: The "Never Wanted Nothing More" package comes with a tailgate party with buffet, ballpark tour, Chesney football jersey and tour T-shirt, premium parking and access to the Sandbar viewing section or floor seats ($609-$719). The "Good Stuff" package ($439-$569) is all that minus the tour, jersey and T.
