Nationals' game against Cardinals washed out

ST. LOUIS -- Tuesday's game between the Nationals and Cardinals was postponed because of bad weather, which included a tornado warning, hail and rain.

It marked the sixth time in 20 days the Nationals have had a day off because of either weather or scheduling.

"It's too many off-days," manager Jim Riggleman said. "That's the thing about scheduled off-days. You know you are going to get some rain in April. To have one the day off before the season started, and then three [scheduled] off-days and now two rainouts, it's like five or six days of no baseball. It's certainly not ideal, but we will make the adjustment."

The game will be made up on Wednesday as part of a day-night doubleheader. It will mark the second time in four days the Nationals will play a doubleheader; the other was on Sunday against the Brewers at Nationals Park. Washington ended up winning both ends of that twin bill.

The first game on Wednesday is scheduled to start at 2:15 p.m. ET and the nightcap will begin at 8:15 p.m. ET. John Lannan, who was scheduled to start on Tuesday, will start Game 1, with Jordan Zimmermann throwing in the later game. The Cardinals will counter with right-hander Jake Westbrook in the first game, while left-hander Jamie Garcia will throw in the nightcap.

Riggleman is planning on making some lineup adjustments. Catcher Wilson Ramos, who was scheduled to start in Tuesday's game, will sit on the bench for Game 1. Ivan Rodriguez will get the start instead.

"I'm going to reverse the catching. I'll catch Pudge in the first game. No particular reason for that," Riggleman said. "Then, I might do some other things. Everything else will probably be the same. I might make one other change. I don't know yet."

Before the weather turned bad on Tuesday, it was announced before the scheduled start time that the game would be delayed. Before the game was officially postponed, tornado sirens went off, then it started pouring rain and hail. At one point, there was hail all over the field.

"I've seen some rain here, buy guys were coming in and saying that they have never seen anything like it. I guess it was really a downpour" said Riggleman, who served as a first-base coach with the Cardinals in 1989 and '90.

The Nationals are currently riding a three-game winning streak, while the Cardinals have won six out of their past eight games.
