Daisuke Yamai pitched a shutout for the first time in four years as the Chunichi Dragons beat the Yokohama BayStars 8-0 in the Central League on Tuesday.

Yamai (1-0), who was making his first start of the season, struck out six while allowing four hits and a walk in a 116-pitch outing. He retired the first five hitters in order before allowing a double, but he bounced back to post four 1-2-3 innings.

“I think everything went too well today. I was able to pitch at my own pace because my teammates scored throughout the game,” said Yamai, who turned 40 on May 10. “I wasn’t thinking about my age too much, but I wanted to do well because it was my first outing since I turned 40. So I’m really glad with the results.”

Yohei Oshima went deep twice as the visitors scored six of their runs on four homers.

After Dayan Viciedo opened the scoring with a second-inning, solo shot, Oshima drove in two runs in the next inning. In his next at-bat in the fifth, he blasted a solo shot to triple the lead.

Yota Kyoda doubled and scored on Zoilo Almonte’s sacrifice fly in the seventh before Ryosuke Hirata capped a three-run ninth with his third home run of the season.

Yokohama cleanup hitter Yoshitomo Tsutsugo, who hit three homers in Sunday’s game against the Yomiuri Giants, was hitless in his four at-bats. The 21-year-old right-hander Satoshi Iizuka (0-4) gave up four runs on eight hits and a walk.
