But despite the noise in the outfield and the droning of electrical saws working to pin up the backstop, his players heard every word.
"All of us realize this part of the season is really the part that counts," said Russ Adams, a junior infielder who is leading North Carolina with a .374 batting average. "It's kind of like a new season; we're starting all over again."
And starting over might be the best thing for the UNC team after a disappointing performance in last week's ACC tournament. From that tournament, UNC earned a second seed in NCAA Regional Division I play.
North Carolina (40-19, 17-7) traveled to Columbia, S.C., on Wednesday to prepare for Friday's 2 p.m. bout with third-seeded James Madison University.
UNC never before has faced the Dukes (43-14) in post-season play. The tournament is double elimination, and the Tar Heels could face two other teams this weekend -- first-seeded South Carolina or fourth-seeded Virginia Commonwealth (38-25).
The Gamecocks (48-14) are hosting the tournament for the third consecutive year at Sarge Frye Field.
Fox cited pitching as the one area UNC needed to improve. During the last few weeks, North Carolina's pitchers haven't been producing at the same level they were during the regular season -- a fact that has caused concern.
"You've got to have a good team," he said. "You have to have very good pitching, and more importantly, you've got to know and expect that you can do it."
Right-handed pitcher Scott Autrey, who has appeared in 15 games, is slated to open the tournament for the Tar Heels. He is 4-3 on the season with a 4.98 earned run average.
