BALTIMORE -- Another round of champagne will have to stay on ice for at least another day for the Toronto Blue Jays.

Their game against the Baltimore Orioles on Tuesday night was postponed because of rain. As a result, the teams will play a doubleheader starting at 4 p.m. ET Wednesday.

In Game 1, the Blue Jays' Marcus Stroman will take on the Orioles' Miguel Gonzalez. Immediately afterward, Toronto's R.A. Dickey faces Baltimore's Kevin Gausman.

Toronto has already clinched a spot in the postseason for the first time since 1993. Nonetheless, there is still much at stake in their remaining six games.

The Blue Jays can seal their first American League East title in 22 years on Wednesday at Camden Yards, depending on the second-place New York Yankees' performance. Toronto is also battling the Kansas City Royals for home-field advantage throughout the playoffs.

Toronto's World Series aspirations got a boost earlier this month with the return of Stroman, who was activated from the disabled list on Sept. 11 after recovering from a torn ACL. Since returning, Stroman has won all three of his starts with a 1.89 ERA.

The Orioles were officially eliminated from the playoffs early Tuesday morning on the East Coast when Houston won 3-2 in Seattle. Until that happened, manager Buck Showalter and the players had refused to give up hope for a third postseason berth in the past four years.

"The first time you see those boxes in the clubhouse, it's not fun," Showalter said. "I haven't see those in the last couple of years."

Baltimore has to win all six of its remaining games to finish with a winning record. It is quite a contrast to last season, when they were entering the playoffs as the AL East champion.

"It's self-inflicted," Showalter said. "We knew it was going to be a tough climb in September. ... We were disappointed last year. There is only one team walking around with their chest stuck out."
