LAKE BUENA VISTA, Fla. -- Pirates starter Charlie Morton and non-roster invitee Brian Burres struggled through four innings, walking seven and plunking two other batters among the first 20 Braves they faced, and host Atlanta upended the Pirates 4-2 this afternoon before 4,004 at Champion Stadium at Disney World.

Morton allowed one run and one hit among his two innings, which included three walks and a hit batsman. He opened the first with a four-pitch walk of ex-Pirates center fielder Nate McLouth, for whom he was traded last June. McLouth stole second. Touted rookie Jason Heyward was hit by the second pitch to him and, after he was erased on a Chipper Jones double-play grounder that moved McLouth to third, Troy Glaus gave Atlanta (2-1) a 1-0 lead with a single to center field.

Morton had two more walks and a passed ball, though he got out of a two-out walk and a steal by Brooks Conrad in the second inning when he retired the other three batters on groundouts.

The Pirates (0-2) tied it at 1-1 with a two-out rally in the third. Delwyn Young singled with one out. Jason Jaramillo moved him to second on a comebacker to the pitcher. Andrew McCutchen walked, and Bobby Crosby followed with an RBI single up the middle.

Burres fared no better than Morton, walking or plunking five of six consecutive batters at one point and allowing two runs in the bottom of the fourth on a Conrad double for a 3-1 Atlanta lead.

Brad Lincoln allowed two hits in his fifth inning. Chipper Jones singled to left on Lincoln's first big-league pitch but was erased when Glaus hit into a double play. Brian McCann doubled next, but Lincoln ended the inning with a three-pitch strikeout of Matt Diaz, all swinging.

Andy LaRoche homered in the seventh.
