Strasburg allows two homers as Nationals fall

LAKE BUENA VISTA, Fla. -- Jason Heyward's fourth-inning home run off Stephen Strasburg highlighted a two-hit night, and the Braves mounted a late rally to beat the Nationals, 6-5, at ESPN's Wide World of Sports Complex on Wednesday.

Chad Tracy, who is vying for a spot on the Nationals' bench, homered in the fourth inning and tied the game with a single in the eighth. He scored the go-ahead run later that inning on a double by Carlos Maldonado.

But Jordan Parraz homered off Ryan Matthews to lead off the bottom of the eighth and even the score. Jose Constanza then reached on an infield hit, moved to second on a fielder's choice and scored on a lined single by Luis Durango to put the Braves back ahead.

Heyward ended an 0-for-12 skid with a solo shot off Strasburg. The Braves right fielder added a sixth-inning double and went 2-for-3 after entering the day 4-for-29 in the exhibition season.

Strasburg was charged with four earned runs and five hits in four innings. His biggest nemesis was Dan Uggla, who gave the Braves a first-inning lead with a two-run opposite-field home run. The Braves second baseman created some more excitement in the third inning with a long sacrifice fly that was caught just short of the wall in left-center field.

Braves starting pitcher Julio Teheran kept the Nationals scoreless for three innings but surrendered a pair of blasts in the fourth. Tracy victimized the highly regarded prospect with a two-run shot, and Jesus Flores added a two-out solo home run. These were the first home runs Teheran surrendered since allowing six during his two-inning stint against the Tigers on March 4.

Randall Delgado, who is battling Teheran for the final rotation spot, followed with three scoreless innings before unraveling in the eighth. Brett Carroll worked a one-out walk and moved to second on a wild pitch. After Delgado fanned Tyler Moore, Tracy drove in Carroll. Maldonado hit a ground-rule double to right-center to score Tracy, and Delgado walked Mark Teahen to load the bases. But Delgado struck out Eury Perez looking to end the frame.

Eric O'Flaherty pitched a perfect ninth inning to earn his first Grapefruit League save.

Up next for the Nationals: Right-hander Chien-Ming Wang will face his former team, the Yankees, on Thursday at Space Coast Stadium. The game will be played at 1:05 p.m. ET and can be seen on MLB.TV. It will mark the first time Wang has faced the Yankees after leaving New York as a free agent following the 2009 season. Wang was 55-26 with a 4.16 ERA for New York from 2005-09. His best seasons were 2006 and '07, when he won a combined 38 games. Wang is expected to throw three or four innings and be followed by left-hander John Lannan, who is expected to pitch at least five innings.
