WASHINGTON -- A teenager among men, Juan Soto has impressed his teammates on the Washington Nationals with his maturity and, even more so, his potent bat.
Soto hit a tiebreaking two-run double in the eighth inning, and Washington beat the Baltimore Orioles 4-2 Thursday night in the deciding matchup of a three-game interleague series between neighboring rivals.
Soto, a 19-year-old rookie, is batting .326 with 16 RBIs in 28 games. Starting in the cleanup spot for the first time, he drew a walk and delivered the game's pivotal hit.
"I think we're all amazed every single day," Washington ace Max Scherzer said. "He puts together great ABs. He has antics and has some flair. He's a great young player. He's just enjoying himself."
Bryce Harper led off the eighth with a double off Mychal Givens (0-4) and Trea Turner followed with a single. After Anthony Rendon struck out, Soto hit a liner into the gap in left-center.
"He's got unbelievable poise," Nationals manager Dave Martinez said of Soto. "No matter what the situation is, he goes out there with a game plan."
Whatever that plan is, it's effective.
"I just try to be focused and keep working," Soto said.
Rendon homered for the Nationals, who received seven strong innings from Scherzer and flawless work from their bullpen.
Newcomer Kelvin Herrera (1-0) pitched a 1-2-3 eighth inning and Sean Doolittle got three straight outs for his 20th save in 21 tries.
Seeking to end a rare run of two straight losses, Scherzer left a tied game after allowing two runs -- both on solo homers -- and striking out nine.
Afterward, the right-hander heaped praise upon Soto for the manner in which he's adapted to playing in the big leagues.
"He has a great feel for the strike zone," Scherzer said. "To have that type of eye, it's remarkable for him to be able to do that at this time and this age and this level."
Activated from the 60-day disabled list before the game, Colby Rasmus homered for the Orioles in his first at-bat since April 6.
"Me and Max, we go way back, so I felt real good," said Rasmus, who had been sidelined with a hip injury.
In addition, Rasmus made an outstanding throw from right field to the plate, nailing Wilmer Difo on a tag-up play in the seventh inning with the score tied.
Mark Trumbo also homered for Baltimore, his sixth of the season and third in four games.
Baltimore starter Kevin Gausman gave up two runs and four hits over six innings. The right-hander was lifted with the score tied, leaving him winless in his last seven starts.
