Former Montreal Expos pitcher Hideki Irabu was arrested Wednesday for allegedly assaulting a bartender after drinking 20 mugs of beer, a police official said.

Irabu, 39, became angered after his credit card was rejected.

He then allegedly pushed the bartender against the wall, pulled his hair and smashed at least nine liquor bottles at a bar in Osaka, Japan, a police official said on condition of anonymity, citing department policy.

The bartender sustained no injuries.

The former major leaguer paid the bill with another credit card.

The police official said Irabu admitted the assault.

Irabu started his career with the Chiba Lotte Marines of Japan's Pacific League and joined the New York Yankees in 1997 on a four-year, $12.8-million US contract.

While with the Yankees, the Japanese right-hander failed to cover first base in spring training once, prompting Yankees owner George Steinbrenner to refer to him as "that … fat toad."

Irabu pitched in 126 major-league games, including 14 with the Expos.

He spent six seasons in the majors with the Yankees, Expos and Texas Rangers before signing with Japan's Hanshin Tigers in 2003.

In the majors, Irabu had a career record of 34-35 with 5.15 earned-run average.

He retired in 2005 and currently lives in California.
