For the second straight day, rain postponed a game between the Orioles and the Pittsburgh Pirates at Camden Yards.
The two clubs will play the two-game interleague series in one day Thursday, with a single-admission doubleheader scheduled to begin at 4:05 p.m.
It marks the first time in 10 years that rain forced back-to-back postponements for the Orioles. The club's games against the Boston Red Sox at Fenway Park were rained out April 13 and 14, 2004.
And it hasn't happened at Camden Yards since two games between the Orioles and the Tampa Bay Devil Rays were postponed April 17 and 18, 2000.
Orioles right-hander Bud Norris will face Pirates right-hander Charlie Morton in the first game Thursday, while Orioles right-hander Chris Tillman and Pittsburgh right-hander Brandon Cumpton are the scheduled starters in the nightcap.
Tillman originally was scheduled to pitch Tuesday, but his start now has been pushed back twice because of the rainouts.
Tillman hasn't pitched since April 23 in the Orioles' 10-8 win over the Toronto Blue Jays at Rogers Centre. He gave up seven earned runs and nine hits in 5 2/3 innings but improved to 3-1 this season.
In his career, Tillman is 11-3 with a 3.75 ERA in 23 starts with six days or more of rest. Pitching with six days of rest April 18 against the Red Sox, he allowed three runs and seven hits while walking four batters in the Orioles' 8-4 victory at Fenway Park.
Norris also will have had six days of rest between starts for the third time this season.
He hasn't pitched since April 24, when he picked up his first win of the year after holding the Blue Jays to three runs and five hits in six innings as the Orioles won, 11-4. In his career, Norris is 3-10 with a 5.06 ERA in 19 starts with six days or more of rest.
Fans with tickets for Wednesday's game will need to exchange their tickets for Thursday's doubleheader. Tickets for Tuesday's game will be honored Thursday and valid for both games. Fans can bring their tickets directly to the gate for admission.
Camden Yards gates will open at 3 p.m. Thursday, with parking lots opening at 2 p.m. Prepaid parking permits for either Tuesday's or Wednesday's game will be good for the doubleheader.
Fans who had tickets for Tuesday's or Wednesday's game and cannot attend Thursday's doubleheader can exchange them for any remaining home game on a dollar-for-dollar basis.
Exchanges can be made at the Camden Yards box office or by mail and must be completed by June 30. Complimentary tickets are not exchangeable.
The Orioles' “I Like Our Guys” T-shirt giveaway that was scheduled for Wednesday has been moved to Thursday. The club said it will have enough giveaway T-shirts on Thursday to accommodate fans who arrive late because it is an “all fans” promotion.
In other news, the Orioles' April 15 rainout against Tampa Bay will be made up as part of a doubleheader June 27 at Camden Yards, according to an industry source.
The team hasn't officially decided the time of the games, but it likely will be a split-admission doubleheader, with games at 1:05 p.m. and 7:05 p.m.
That would allow the Orioles to collect gate revenue for two separate games. Fans with tickets for the April 15 game who cannot attend the June 27 game will be able to exchange their tickets.
An official announcement on the doubleheader against the Rays could come later this week.
Television restrictions prevented the Orioles from making up the game as part of a day-night doubleheader June 28, the source said.
Even though the teams share a day off June 26, the collective bargaining agreement prevents teams from playing more than 20 consecutive days, so the game also could not be rescheduled for that day.
