Murofushi, the only thrower who cleared the 80-meter mark, was called for a foul in his first toss but measured 81.92 in his fourth attempt to outperform second-place Krisztian Pars of Hungary (79.59) and Olli-Pekka Karjalainen of Finland (78.80), who took third.

"It was good that I was able to relax out there. I was able to accomplish my personal goals today.

It's important not to get tense," said Murofushi, who set a national record of 84.86 meters in the meet last year.
