BALTIMORE (AP) Gunnar Henderson hit in the first, Dean Kremer stopped a four-start losing streak and the Baltimore Orioles salvaged a split of their two-game series against Washington with a 4-1 victory Wednesday night. Kremer (5-9) outdueled DJ Herz (2-5) in a sharply pitched game, allowing a run and five hits over six innings. Yennier Cano and Cionel Prez each worked a perfect inning of relief, and Seranthony Domnguez followed with a hitle s ninth for his second save since joining the Orioles before the trade deadline. It was the first scorele s performance for the Baltimore bullpen in six games. Over the previous five, Orioles relievers had allowed 11 runs in 14 innings. It was the first hitle s game for the bullpen since July 19. It felt like a normal baseball game. We haven't played many of them, Orioles manager Brandon Hyde said. We pitched really well, we were solid defensively. Gunnar huge hit early, and then a nice little rally there late in the game. Herz permitted two runs and four hits in six innings. Henderson gave Baltimore a 2-0 lead with his 30th home run of the year, and that was all the Orioles Jackson Chourio Jersey needed. The only run for the Nationals came in the second on Alex Call's RBI double. Anthony Santander nearly made a running catch in right field but the ball popped in and out of his glove. Baltimore entered a half-game behind the Yankees atop the AL East, with New York playing at Chicago on Wednesday night. Baltimore's Coby Mayo lined a single to left in the fifth for his first big league hit after an 0-for-16 start. Sigh of relief, for sure, Mayo said. I was never too stre sed about the hit, but then it gets to you a little bit. Mayo drew a walk in the seventh, and fellow rookie infielder Jackson Holliday followed with an RBI single. A sacrifice fly later that inning by Adley Rutschman made it 4-1. Holliday made a sliding stop to start a slick double play up the middle with Henderson that ended the game. TRAINER'S ROOM Orioles: Hyde said RP Jacob Webb (right elbow) still hasn't played catch yet, but that may happen in the next few days. RP Danny Coulombe (left elbow) is in the entry stage of throwing. Nationals: 3B Jos Tena (thumb) did not play. ... RHP Jacob Barnes was hit on the leg by Ryan O'Hearn's comebacker in the seventh but remained in the game. UP NEXT Nationals: Begin a four-game set at Philadelphia on Thursday night.
