Banks died in January at the age of 83.
The Rockies held a moment of silence for Banks and put a tribute to him on the scoreboard.
The Cubs held a moment of silence ahead of their Opening Night game against the St. Louis Cardinals to honor Banks and former Cardinals outfielder Oscar Taveras. Taveras was killed in a car crash in October.
Chicago is also honoring Banks during home games with a large photo tarp in the unfinished Wrigley Field bleachers.
Banks, nicknamed "Mr. Cub," spent his entire 19-year career with the Cubs and was the first African-American player in franchise history. He was named to 14 All-Star Games and was inducted into the Baseball Hall of Fame in 1977.
