Construction officials don’t expect a delay in the opening of the new ballpark for the Texas Rangers after a fire damaged an area near the roof. Officials say the fire started when sparks from welding work ignited combustible materials in a sub-roof area of Globe Life Field. The first game in the $1.2 billion stadium with a retractable roof is set for March 23. It’s an exhibition between the Rangers and St. Louis Cardinals. A construction executive says some metal decking damaged in the fire will be replaced. The investigation is continuing.
