<P> After the 2008 season, the Astros' groundskeepers began installing 2.3 acres (9,300 m) of a new turfgrass playing surface at Minute Maid Park . The Astros also became one of the first to use the new Chemgrass, later known as AstroTurf after its first well - publicized use at the Houston Astrodome in 1966 . </P> <P> In honor of longtime Astros broadcaster Milo Hamilton, the City of Houston officially renamed a portion of the Ballpark District to the "Hall of Fame District", and the portion of Hamilton Avenue that runs within that district to "Milo Hamilton Way" on April 8, 2009 . </P> <P> For the 2011 season, the park added a large Daktronics HD screen nicknamed "El Grande" replacing the original one in center field . At 54 feet high and 124 feet wide, it is the fourth largest scoreboard in Major League Baseball, behind Safeco Field (home of the Seattle Mariners), Progressive Field (home of the Cleveland Indians), and Kaufmann Stadium (home of the Kansas City Royals). The old screen was taken out and replaced by billboards . Additionally, a smaller HD screen was added on the far left field wall . The ring of advertisement screens around the park were replaced in favor of HD ribbon boards . </P> <P> After the Astros reverted to their original colors and logo in 2013, much of Minute Maid Park was repainted to navy and orange from brick red . Signs with the previous logo and colors were also replaced . More than 4,500 US gallons (17,000 l) of paint were used and over 1,000 signs were replaced . </P>
