Making matters worse, The Astros wore their gray uniform tops, which are heavier than their red tops.
"The heat doesn't bother me one iota," said Astros first baseman Lance Berkman, a Texas native. "We used to play triple-headers in this stuff when I was a kid."
Houston manager Brad Mills said having a younger lineup on the field would be beneficial, but that didn't go into his thinking when filling out the lineup card. Starting pitcher Josh Banks and catcher Jason Castro played in the heat all season at Triple-A Round Rock.
"There's obviously a time where it becomes too hot, and if that's today both teams have to play in it," Mills said. "We'll go through it. Our pitcher has been in Round Rock and pitched in some heat before, and the catcher is a younger guy and has caught in it before."
