I don’t know what it is about sex and slumps, but using the former to solve the latter is a tradition old as baseball, from Mark Grace’s superstition about going to bed with an ugly woman as a “slump buster” to “Nuke” LaLoosh wearing Annie Savoy’s garters as a way to stop overanalyzing things in Ron Shelton’s Bull Durham. Now comes a report from the New York Post in which the Yankees’ Jason Giambi admits to an even cheekier device: wearing a tiger-striped gold lame thong under his uni. “I only put it on when I’m desperate to get out of a big slump,” the slugger told Portfolio.com. (Or when he needs easy access for a shot in the ass, chimed in my pal Kate, Giambi being an admitted steroid user.) But that’s not the worst of it. He has gone on to share the device with teammates Derek Jeter, Johnny Damon, and Robinson Cano. “All of them wore it and got hits,” Giambi insisted. “The thong works every time.” Suddenly the White Sox’ inflatable dolls seem a lot less tawdry — and a lot more hygienic.
