TOKOROZAWA, Japan (Kyodo) -- Rookie Shota Hamaya allowed a run over six innings and 37-year-old Takumi Kuriyama drove in two runs for the Seibu Lions in their 3-1 Pacific League victory over the Lotte Marines on Wednesday.
Hamaya (1-0), the Lions' second pick in last fall's draft, allowed four hits while striking out three. The lefty did not issue a walk.
"I was so nervous before I went to bed last night that I barely slept," the 21-year-old said. "(When I got behind) I focused on making my pitches and if they hit them, then they hit them. I just tried to throw them as well as I could."
Kuriyama, who had four hits, homered off Marines' lefty Kazuya Ojima (5-6) in the first. He capped a two-run fifth-inning rally with an RBI single.
Right-handers Ryosuke Moriwaki, Kaima Taira and Tatsushi Masuda finished up for the Lions with one perfect inning apiece. Masuda earned his 19th save.
At Hotto Motto Field Kobe, Daiki Tajima (2-4) outdueled Hideaki Wakui (8-3) with his first career shutout, a two-hitter, in the Orix Buffaloes' 2-0 win over the Rakuten Eagles.
At Sapporo Dome, Yuki Yanagita drew a game-tying bases-loaded walk and Alfredo Despaigne singled in two runs to break the tie in the SoftBank Hawks' 5-4 win over the Nippon Ham Fighters.
In the Central League, reserves Shunta Tanaka and Soichiro Tateoka each homered and combined to drive in six runs for the Yomiuri Giants, who held on to beat the Hanshin Tigers 7-6 at Tokyo Dome and win a ninth straight game for the first time in eight years.
At Tokyo's Jingu Stadium, a pair of seventh-inning RBI pinch-hit singles lifted the Yakult Swallows over the DeNA BayStars 3-2.
At Hiroshima's Mazda Stadium, Jose Pirela and Ryuhei Matsuyama each homered and drove in two runs for the Hiroshima Carp in a 9-2 win over the Chunichi Dragons.
