The conditions were even hotter on Friday for the start of a weekend series in St. Louis.
A day after playing in 101-degree conditions at Miller Park, the temperature reading at Busch Stadium during warmups on Friday was 105 degrees. By first pitch, the thermometer dipped to 103, which still tied the hottest game-time temperature in Marlins history. A game in Arizona on June 14, 1999, was also 103 degrees at first pitch.
Marlins manager Ozzie Guillen said he doesn't want his players complaining about the heat.
"There is a reason we don't take batting practice today and tomorrow, because I don't want to hear that," Guillen said. "If somebody says it is hot, we'll send him to the hotel, I don't want him here. Especially, we come from Miami, and they played in the worst ballpark ever to play [Sun Life Stadium]. I don't want to hear it."
Marlins hitting coach Eduardo Perez formerly played for the Cardinals, and he knows how hot it gets in St. Louis.
"On the field itself, you try to keep the guys that are in there hydrated more than anything," Perez said. "It's pretty much a lot of focus, you can't throw away at-bats. There is a tendency to throw away at-bats. I think it's harder on the pitchers than it is on the hitters. We need to keep them out there as long as we can, offensively.
"The beauty of it is, they have to [also]. Our offense has to try to keep their defense out there as long as possible. If we can do that, we should be good."
