Langer, the two-time Masters champion from Germany, will become eligible for the Champions Tour when he turns 50 on Aug. 27. Villegas, from Colombia, is a 25-year-old rising star.
Both played well in front of fans who lined fairways to watch them. Langer shot 65 to go to 3-under par 137 and Villegas posted a 67 to reach 6 under.
Despite the generation gap, they talked frequently. Villegas said he learned a lot from the international star who is old enough to be his father.
'He's a great guy. I had some interesting chats with him about working out and about a lot of stuff. You can always learn from someone like that,' Villegas said. 'On the first tee (introductions) they say, 'Two-time Masters champion.' That's tells you everything.'
Langer enjoys playing with young golfers like Villegas even though they often outdrive him by 50 yards. But he said Villegas is more than a golfer who hits the ball a mile.
'He's actually down-tuned a little bit with his drives (this season),' Langer said. 'He learned he had to control his distance more and his ball flight. He can definitely hit it far. At the same time, he plays very controlled.'
Defending champion Corey Pavin stumbled to a 3-over par 73 Friday and missed the cut in the U.S. Bank Championship. But 2003 champion Kenny Perry fired a 5-under 65 to get into contention for another victory.
'I moved closer,' said Perry, 6 under for the tournament. 'I hit a lot of good shots.'
A positive for Perry going into the weekend is that he loves playing Brown Deer Park Golf Course.
'I like coming here. I feel very comfortable walking around this golf course,' he said.
Jeff Sluman, who won in 2002, also made the cut but two-time champion Carlos Franco didn't.
REMEMBER MY NAME
A lot of people still mistakenly refer to the U.S. Bank Championship as the Greater Milwaukee Open, the name it had for decades until a change in 2005.
Even some players get that wrong.
After his second round, a 1-over 71, Appleton native J.P. Hayes was asked if the tournament felt different because of the absence of Madison golfers Steve Stricker and Jerry Kelly, who are playing in the British Open.
'Not from my standpoint. It feels like the same GMO to me ... U.S. Bank Championship,' he said.
WILSON WINS ALL OVER
Menomonee Falls native Mark Wilson shot even-par 70 Friday to make the cut at 3-under 137.
Earlier this year, Wilson won his first PGA tournament, the Honda Classic. He is now looking forward to another big event, one that is even more important than winning tournaments. His wife, Amy, is due to give birth to their first child in about seven weeks.
'The child thing I'm looking forward to more than any golf round I've ever had,' he said.
Asked if winning tournaments or becoming a father was harder, Wilson answered, 'To win the golf tournament, no question.'
