Kazuma Okamoto blasted a two-run home run to give the Yomiuri Giants the lead and Gerardo Parra drove in three runs in a 7-1 win over the Hanshin Tigers in the Central League on Sunday.

Playing behind closed doors at Tokyo Dome, the Giants completed a three-game sweep of the Tigers in their first series of a season that was delayed for three months due to the novel coronavirus pandemic.

Dominican right-hander Angel Sanchez, coming off two solid seasons in South Korea, pitched 5-2/3 innings and picked up the win in his Nippon Professional Baseball debut. He allowed four hits, including a leadoff home run, and four walks, while fanning one.

Okamoto, the Giants' cleanup man, hit his first homer of the season off lefty Onelki Garcia (0-1) in the fourth when the Giants were trailing by a run. Parra singled in a run and scored before captain Hayato Sakamoto capped the five-run inning with an RBI single.

In the fifth, Okamoto had his third hit of the day and Parra homered for the second straight day, a two-run shot that put the game out of reach.

"I think we got off to a great start, and each and every player fulfilled their roles," Giants manager Tatsunori Hara said.

Sanchez, who made his major league debut in 2017 with the Pittsburgh Pirates, joined the SK Wyverns in 2018 and claimed 17 wins last season. He signed with the Giants during the offseason.

At Fukuoka's PayPay Dome, Seiya Inoue's second-inning grand slam lifted the Lotte Marines to a 5-1 win over reigning Japan Series champion SoftBank Hawks.
