St. Louis ? Jeff Weaver and Anthony Reyes sat together in the interview room, looking at each other and waiting for questions. There was one they couldn’t answer: Who’s going to pitch Game 5 of the World Series for the St. Louis Cardinals?

“I don’t know which it’s going to be, so they’re both getting ready,” St. Louis manager Tony La Russa said Wednesday.

That decision will be delayed another day because Game 4 was postponed by rain Wednesday night. Jeff Suppan and the Detroit Tigers’ Jeremy Bonderman will try again tonight, with the teams facing another iffy forecast.

The Cardinals lead the best-of-seven series, 2-1.

Tigers manager Jim Leyland wouldn’t discuss his options after Game 4 was called. Justin Verlander had been set to go in Game 5, but Kenny Rogers could move ahead of him if the Tigers face elimination.

“You can speculate as you all do,” Leyland said. “You can second guess how the rotation’s going to go the rest of the series, whatever you want to do.

“Jeremy Bonderman is pitching the next game for the Tigers, he’s earned it. He’s one of our horses and he will be on the mound when Game 4 starts, whenever that may be.”

After the Cardinals’ third rainout of the postseason, La Russa said Reyes and Weaver would pitch Games 5 and 6 with the order to be determined by where the series stands. Weaver could go on regular rest in Game 5 on Friday followed by Reyes, a rookie, and ace Chris Carpenter on regular rest in a Game 7.

That’s the most likely scenario, although La Russa noted that he could bring back Carpenter on three days’ rest in Game 6 if the Cardinals needed a win to keep the series going.

“What our record is has a lot to do with it,” pitching coach Dave Duncan said.

The rainout means Suppan, the MVP of the NL championship series, would be able to pitch only once in the series.

La Russa wasn’t looking beyond the next game.

“Just play the one tomorrow and don’t get too far ahead,” he said.

The pregame scene was unusual and somewhat awkward, although neither right-hander sounded too worried.

“I always go at it like I’m going to pitch, so I just do everything I was going to do before, like I’m going to pitch,” Reyes said. “If it’s not my time, I just try to prepare for the next one.”

Said Weaver: “Another day of rest always helps, but I feel good right now.”

Verlander struggled in a matchup of rookie starters against Reyes in Game 1. While Reyes was brilliant for eight innings in a 7-2 victory that night at Comerica Park, Verlander, a 17-game winner, gave up six earned runs in five-plus innings.

He has a 10.80 earned-run average against the Cardinals and a 7.47 ERA in three postseason starts.

The Tigers were disappointed with Verlander’s lack of velocity in Game 1. Normally around 100 mph, Verlander’s fastballs were in the low 90s.

“I wasn’t really driving with my legs as much as I had been earlier in the year,” he said. “We worked on that a little bit. I think it was just a mix of maybe the mechanics and how my arm felt that day.”
