"It's a special feat. It's a special feat in any era," said Pirates manager Clint Hurdle. "The game is cycling back to speed. The home runs are not the multitude and magnitude they used to be. It speaks to his skill set."
The 24-year-old McCutchen is the first Pirate to join the 20-20 club since Nate McLouth in 2008.
"It's good to have that," said McCutchen, who leads the team with 20 stolen bases. "Definitely a stepping stone for me. Still got a lot of ball to play, so still going to continue to keep going out there and playing harder. Try to finish strong."
A first-round selection (11th overall) by the Pirates in the 2005 First-Year Player Draft, McCutchen is in his second full season in the Majors and made his first All-Star team this year.
"I just play," said McCutchen, who homered in the first two games of the three-game series with Houston. "I let the game take care of itself. As long as I go out there and do what I need to do. I'm not trying to set up a goal, I stay within myself."
