ATLANTA— Georgia Tech turned up the defensive pressure when Pittsburgh added a freshman starter to an already inexperienced offensive line. Jeremiah Attaochu had two of Georgia Tech's season-high five sacks, Robert Godhigh ran for two touchdowns and the Yellow Jackets beat Pitt 21-10 on Saturday night. Left tackle Dorian Johnson made his first start, becoming Pitt's first true freshman offensive lineman to start in seven years.
