WASHINGTON (AP) Monday night's game between the Baltimore Orioles and Washington Nationals has been postponed because of rain.
The clubs will make up the game Thursday, a mutual off day, at 4:05 p.m.
The three-game series with playoff implications now opens Tuesday night, with Monday's scheduled starters pushed back a day.
Orioles right-hander Ubaldo Jimenez (11-9) will face Nationals lefty Gio Gonzalez (11-7).
Chris Tillman will start Wednesday and Tyler Wilson will start Thursday for Baltimore. The Nationals have not announced their starters after Tuesday.
The Orioles began the day 5 1/2 games out of the second AL wild-card spot. The Nationals trailed the NL East-leading New York Mets by six games.
Orioles: CF Adam Jones was out of Monday's lineup with back spasms, manager Buck Showalter said, even though Jones insisted he was dealing only with recurring soreness. ''I'm human, though,'' Jones said. ''Let me have a day off without it being a story. It's not a story.'' Jones has played 159 or more games in each of the past three seasons, but has dealt with shoulder and ankle issues this year. . RHP Miguel Gonzalez (shoulder) expects to throw a simulated game on Wednesday and hopes to make two starts before the close of the season.
Nationals: INF Ryan Zimmerman (left oblique strain) has missed 10 games and has not swung a bat since. ''Next couple of days hopefully,'' manager Matt Williams said. . Danny Espinosa (right hamstring strain) will have an MRI Tuesday, Williams said.
Orioles: Jimenez (4.31 ERA) will try to improve to 3-0 in September.
Nationals: Gonzalez has allowed three earned runs over his last three starts (18 1-3 IP).
