Worth noting

• The Nationals made a late lineup switch on Thursday morning, inserting shortstop Ian Desmond into the game in place of Anthony Rendon. Desmond has been dealing with a blister on his left hand. All-Star Bryce Harper was also back in the lineup after sitting out Wednesday night's game with an injured left knee.

Desmond went 1-for-4 with a walk, a run and two strikeouts, but Harper stole the show with his first career walk-off homer to finish 3-for-5.

• Entering Thursday, Tyler Moore had reached base safely in all 10 games since being optioned to Triple-A Syracuse for the second time this season. Moore was hitting .417 with three doubles, two home runs, 11 RBIs and nine walks in that span. He didn't play in the Chiefs' game on Thursday

• Outfielder Billy Burns is riding a 20-game hitting streak at Class A Advanced Potomac entering Thursday night's game, during which he has hit .352 with 13 stolen bases. The 23-year-old leads the Carolina League in on-base percentage (.412), steals (42) and triples (seven).

• The Nationals learned on Wednesday that D.C. United of Major League Soccer had reached a tentative agreement with Mayor Vincent Gray to build a new stadium just a few blocks away from Nationals Park in the southwestern part of the city.

"On behalf of the Lerner family and all of us here at the Washington Nationals, we would like to congratulate D.C. United and Mayor Gray on reaching a tentative stadium deal that will undoubtedly benefit all sports fans in the nation's capital," the team said in a statement. "We look forward to welcoming D.C. United to the neighborhood."

D.C. United currently plays at RFK Stadium.
