Sunday’s heat was definitely hard on the players and fans at the Ballpark in Arlington where the Rangers played a rare mid-summer day game.  Normally, Major League Baseball grants the team a waiver permitting them to play most of their Sunday games under the lights.  But due to TV commitments with ESPN, the team’s request for a waiver was turned down, so the first pitch was a little after 2 p.m. meaning the game was played during the hottest hours of the day.  The heat was un-doubtedly the main reason attendance was held down around 30-thousand even though the stadium had been sold out to its capacity of more than 46-thousand for the previous three games, all played at night.  During the worst of Sunday’s heat, more than three dozen fans were treated for heat-related issues at first aid stations at the Ballpark.
