The Houston team presented the Bush family with replica commemorative bricks honoring President Bush and the former first lady, who were constantly present for Astros games in their latter years.
A video tribute dedicated to the first couple was also played, showing the bricks that are now placed in front of Minute Maid Park.
The couple's son, Neil Bush, and their grandsons, Pierce and George P. Bush, were present, and George P. Bush threw out the first pitch.
