Wataru Matsumoto worked five innings to win his pro debut for the Saitama Seibu Lions in a 9-3 Pacific League victory over the Orix Buffaloes on Sunday.

The 22-year-old Matsumoto, the Lions’ first pick in last autumn’s draft, allowed two runs on four hits and two walks, while striking out one at Kyocera Dome.

The Lions opened the scoring with some tenacious batting against first-year right-hander Tyler Eppler (0-2), who gave up three runs over 3⅔ innings. Seibu catcher Tomoya Mori went 3-for-5 with a double and a seventh-inning grand slam to put the game away.

“Having received this opportunity, I was keen just to pitch for all I was worth from the get-go,” Matsumoto said. “Getting the early lead allowed me to just focus on my pitching.”

Matsumoto (1-0) only faced two tough spots, pitching out of a two-on, one-out jam in the second and allowing just two runs in the fifth, when he surrendered three hits and a walk.

“I was struggling a bit toward the end of my outing, but I pulled through by just focusing on throwing it to Mori’s mitt,” Matsumoto said. “My only thought was to have good arm action and execute my pitches.”

Lions leadoff man Shogo Akiyama, who will likely seek a major league job next season as a free agent, went 4-for-4 with a walk and scored two runs.
