After going down a break in the third set against Stanislas Wawrinka, the 2006 finalist sat in his chair at the changeover and whacked his racket seven times on the court until it was completely mangled.
He then calmly gave it to a ballboy before picking three more from his bag — two still in plastic wrappers — and breaking those one by one.
Baghdatis recovered to win the set but lost the match 7-6 (3), 6-4, 5-7, 6-1 on Wednesday.
The Grand Slam Committee will meet on Thursday to decide on the size of his fine. Regulations say a player can be fined up to US$2,000 for each incident of racket abuse.
