A number of setbacks would delay the opening of this stadium until July 16th 1970. When it was unveiled, the Pirates had succeeded in accomplishing everything they wanted out of a stadium… hundreds of luxury boxes, an easy to maintain field and facility and a capacity that went from 41,000 to a final maximum for baseball of 58,000. The artificial turf utilized little suction carts that would drive around the
field after a rain, that would suck up all the water and then disperse it to a drainage system. Eventually that gave way to a drainage system built underneath the turf. Renovations over the years including moving the bullpens around to various parts of the stadium and in 1975, the outfield fences were brought in to increase the number of home runs hit at Three Rivers.
