Texas Rangers pitcher Kohei Arihara needs shoulder surgery and will be sidelined for at least 12 weeks, manager Chris Young said Saturday.
According to The Associated Press (h/t ESPN), Young told reporters that Arihara has an aneurysm in his pitching shoulder. Dr. Gregory Pearl, a vascular surgeon, will repair Arihara's posterior circumflex humeral artery on Thursday in Dallas.
Arihara has been on the 10-day injured list since May 9. He signed a two-year, $6.2 million contract with the Rangers after spending six seasons with the Hokkaido Nippon Ham Fighters of Japan's Pacific League.
The 28-year-old is 2-3 this season with a 6.59 ERA, 1.535 WHIP and 17 strikeouts in 28.2 innings.
Left-hander Hyeon-Jong Yang has taken Arihara's place in the rotation. Texas is fourth in the AL West with a 21-27 record.
