SENDAI (Kyodo) -- Hideto Asamura went deep three times and drove in seven runs on Tuesday as the Rakuten Eagles earned their 1,000th win in Nippon Professional Baseball, a 12-4 rout over the Lotte Marines.
The slugging infielder went 4-for-4 in front of his home crowd at Rakuten Seimei Park Miyagi and ended Ayumu Ishikawa's bid for a seventh straight win.
After drawing a walk in the first inning, Asamura hit a solo shot in the fourth, crushed a two-run go-ahead blast in the fifth and capped the scoring with a three-run bomb in the eighth for his 25th, 26th and 27th homers of the season.
The Marines have given up 10 home runs to Asamura over 16 games.
"He's Rakuten's main weapon, so it's understandable that we'll lose if he's hitting like that," Marines manager Tadahito Iguchi said. "We all have to be vigilant, the battery included."
Ishikawa (6-3), who yielded a leadoff solo homer to Kazuki Tanaka after taking the mound, was charged with eight runs on nine hits and three walks over 6-1/3 innings.
The Marines tied the game in the third on a wild pitch from Eagles lefty Wataru Karashima to Hisanori Yasuda, who followed up with a go-ahead single for the lead, but the visitors lost it two innings later and never recovered.
Karashima, who is 0-3 this year, exited in the fourth after he drilled former big leaguer Leonys Martin near the back of his head, prompting both benches to clear.
Daichi Suzuki sparked a fifth-inning rally for the Eagles with a two-out RBI single before the Eagles reclaimed their early lead on Asamura's second homer of the game.
Former Colorado Rockies pitcher D.J. Johnson (1-0) earned his first win in Japan after retiring the side in the top of the frame.
Rakuten, who joined NPB in 2005, earned their third straight win.
