Maggert, 48, has won three times on the tour but only one of those victories has come in this century. He captured the St. Jude Classic in 2006, but has had only six Top 10 finishes since then.
He had to make successful appearances in the PGA Qualifying Tournament at the end of the 2009 and 2011 seasons just to keep his playing privileges on the circuit and has missed the cut in eight of his last 11 appearances this year.
Maggert began his round on the back nine Thursday and birdied four of the first six holes. He had an eagle at the par-5 third before suffering two bogeys.
Also at 68 was John Daly, who kept his round together despite making a double bogey at the par-3 11th.
This is only the fifth tournament of the year in the United States for Daly and he has survived the cut in three of the other four. His highest finish, however, has been a tie for 41st.
