Tasuku Hashimoto hit a grand slam and Yuta Omine pitched six strong innings as the Chiba Lotte Marines beat Yu Darvish and the Hokkaido Nippon Ham Fighters 5-2 on Thursday.
The Marines opened the scoring in the fourth inning when Hashimoto drove a low inside fastball from Darvish (11-4) over the right-field wall with two outs and the bases loaded at Sapporo Dome.
Daisuke Hayakawa lofted a sacrifice fly in the eighth to give the Marines a three-run cushion.
