Yoshio Itoi made Giants ace Tomoyuki Sugano pay for his biggest mistake, homering in the fifth inning to power the Hanshin Tigers to a 1-0 win over Yomiuri on Friday.

Sugano (5-3), who had won his last five decisions, had not allowed a runner through 4-1/3 innings at Koshien Stadium . But the right-hander fell behind 2-0 to the left-handed-hitting Itoi, who crushed a fat cutter and drove it into the right-field stands.

Tigers starter Yuta Iwasada (3-1) scattered six hits and a walk over seven innings with the help of eight strikeouts. Kentaro Kuwahara worked a 1-2-3 eighth, and closer Rafael Dolis worked around Casey McGehee’s ninth-inning leadoff single to record his 15th save.

“My opponent tonight (Sugano) is a great pitcher. Make no mistake about that,” the lefty Iwasada said. “I knew that when I got into a jam, I had to work carefully with my catcher to get out of trouble.”

After Itoi homered, an error, a single and a two-out walk to Iwasada loaded the bases, but Sugano got out of thejam with one of his 10 strikeouts. Sugano surrendered a leadoff triple in the sixth, but once more dug in deep to keep Kento Itohara from scoring.
