Orioles beat Nationals, 5-1, reduce magic number to 1; Rays defeat Red Sox to avoid elimination

BALTIMORE—The Orioles’ celebration will have to wait another night. While the Orioles took care of business, reducing their magic number to one with a 5-1 win over the Washington Nationals before an announced crowd of 24,278 at Camden Yards on Wednesday night, the Tampa Bay Rays didn’t help.

The Rays beat the Boston Red Sox, 5-0, and if the Orioles defeat Boston on Thursday night, they’ll clinch their first American League East title since 2014.

The Orioles (99-59) are 40 games over .500 for the first time since the end of the 1979 season. They swept the four games they played against Washington (69-90), allowing just one run.

Adley Rutschman hit a two-run home run, his 20^th, in the third against Nationals starter Patrick Corbin.

Jorge Mateo walked, leading off the fifth, moved to second on a passed ball by Kelbert Ruiz, stole third, his 30^th of the season, and scored on Rutschman’s single to right. Jordan Westburg’s bases-loaded walk scored Anthony Santander and chased Corbin (10-15).

Cedric Mullins doubled to start the sixth against Andrés Machado. Mullins moved to third on Mateo’s bunt and scored on Hays’ single for a 5-1 lead.

Oriole starter Grayson Rodriguez (7-4) allowed a first-inning single to Kelbert Ruiz, and retired 11 straight until Dominic Smith doubled in the fifth. Smith scored on Jake Alu’s single.

Rodriguez allowed one run on six hits in 5 2/3 innings with five strikeouts and no walks.

Danny Coulombe, Jacob Webb and Tyler Wells combined to retire the final 10 batters.
