When Frank Thomas was released by the Toronto Blue Jays earlier this season one couldn't help but wonder if Jason Giambi was far behind. At the time he was having quite the terrible season. For the month of April Giambi had a paltry .164 batting average and a slugging percentage of .411, or over .100 points below his career average. Well he's turned all that around and what has changed? Well isn't it obvious: it's that little critter above his lip. Since May 17 when the caterpillar first showed up, Giambi's numbers are out of this world. Take a look at these numbers: G = 40, AB = 130, BA = .338, OBP = .419, SLUG = .715, OPS = 1.134, HR = 11. Needless to say starring in 70's porn part time has brought Giambi luck. But is his mustache the best Yankee 'stache ever? Checkout past Yankees who have donned the whiskers and vote on who's are the best.
