Silicon Valley insider Scott McNealy is hoping for the best Father's Day weekend ever, as he caddies for his 18-year-old son at the U.S. Open golf tournament.
Maverick McNealy, an amateur, is trying to make the cut at Pinehurst in North Carolina. After the first round Thursday, he was 4 over par.
"He probably needs to shoot even [par], 1 over, 2 over, something like that to have a shot at making the cut and spending the weekend out here," Scott McNealy beamed in a "Squawk Box" interview Friday. "But no matter happens, it's an absolute blast."
The elder McNealy, co-founder of Sun Microsystems, added that Maverick's three brothers—aged 12, 14 and 16—were helping out on the driving range Friday morning before the second round.
Maverick McNealy, a standout on the Stanford University golf team, is pursuing computer sciences in the classroom.
"The night before he did the 36-hole qualifier [for the Open] … I had to tell him to go to bed. He was working on a C++ program that was solving mazes with four different, user-selectable algorithms."
"After the qualifier last week, he had four exams at Stanford that finished at 10-o'clock Friday night. We moved him out of his dorm on Saturday. And then we took the first flight out Sunday morning to Pinehurst."
Scott McNealy, a good golfer in his own right, played at Harvard where he earned a bachelor's degree in economics. He also has an MBA from the Stanford Graduate School of Business.
The 59-year-old helped start Sun Microsystems in 1982. Nearly 30 years later, Oracle bought Sun for $7.4 billion.
McNealy said he hopes his son has a "great amateur career" and then goes on to do other things. He worried about the "gypsy lifestyle" of a pro golfer, always on the road traveling from tournament to tournament.
