SIDELINES : Tennis Tour Gets New Executive

KEY BISCAYNE, Fla. —  Mark Miles of Indianapolis, director of corporate relations for Eli Lilly and Co., will replace Hamilton Jordan as chief executive officer of the ATP Tour, the tennis group said today.

In a statement, the ATP said Miles, 36, of Indianapolis will replace Jordan “after a period of transition.” Jordan will become chairman of the board of the tour.

“I am happy and comfortable to be turning over my responsibilities to Mark,” Jordan said in the statement. “In a sense, Mark brings the best of both worlds to this position. He is an outsider in the sense that his professional career has been outside of tennis. . . . Yet Mark has played tennis all his life.”
