under wraps
adj.— «Stevie Wonderboy’s performance was so dominating that the victory was completed with jockey Garrett Gomez having a firm hold on the reins—”under wraps” in racing parlance—because having the colt further extend himself was obviously unnecessary.» —“It’s a wondrous end to Del Mar’s $608 million meet” by Hank Wesch in Del Mar Union-Tribune (San Diego, California) Sept. 8, 2005.
