Monday night's game between the Orioles and Texas Rangers was postponed by rain. The teams are scheduled to play a night game Tuesday, and Monday's game will be made up Wednesday at 5:05 p.m. EDT as the opener of a doubleheader.
Millar started the day with a run of 46 straight games in which he reached via a hit, walk or hit by pitch. It's the team's longest such streak since Cal Ripken had a 46-game run in 1998, and only three games short of tying Ken Singleton's club record of 49 in 1977.
Millar hasn't missed reaching base since June 20.
"Streaks are fun. I had a 70-something streak in the minor leagues before (Kevin) Youkilis ended up tying it," Millar said. "I like streaks. Hopefully it will go on, and it will spotlighted on the bricks on the warehouse out there."
Millar was jokingly referring to the number 2131, which was placed on the warehouse beyond the right-field wall at Camden Yards when Ripken broke Lou Gehrig's record of playing in 2,130 consecutive games.
Millar and the Orioles were glad Monday's game was called off after a delay of less than a half-hour.
"This is the way to do it. Everybody knew right away," Millar said.
"We always want to play, but we didn't want to wait until 10 or 10:30 to start the game," Orioles manager Dave Trembley said.
The Rangers, however, were disappointed with the twi-night doubleheader because it means they will get back to Texas in the wee hours of Friday morning.
"We had hoped for an earlier start," assistant general manager Thad Levine said. "We would have preferred to do it tomorrow."
Rain is in the forecast Tuesday, too, so the Orioles got permission from Major League Baseball to hold the doubleheader Wednesday.
Daniel Cabrera, who was scheduled to start for Baltimore on Monday night, will pitch in the doubleheader Wednesday along with rookie Garrett Olson. Erik Bedard will start for Baltimore on Tuesday night.
Texas manager Ron Washington was planning to limit Padilla to around 100 pitches. Padilla has started once since a 51-day stint on the disabled list with right triceps irritation.
Washington said the extra day of rest probably won't make a difference for Padilla.
