◆パ・リーグ　オリックス３―５西武（２１日・京セラドーム大阪）

Seibu Lions Lions manager Fumiya Nishiguchi explained after the game that he was seen talking to home-base umpire after the fifth inning, saying, "I was saying, 'Isn't that a balk?' and 'If possible, please review the video after the game,' and then I came back."

In the fifth inning, with a five-run lead, Canario singled to left hit with one out, then stole second base during Kojima's at-bat, putting a runner on second with one out. After Kojima grounded out to third base, making it two outs with a runner on second, Canario attempted to steal third base with a 3-1 count during Koga Yu's at-bat. However, opposing starting pitcher Kuri, who appeared to have briefly stopped pitch, immediately threw a pickoff throw to third base. Canario was caught in a rundown between third and short and was caught stolen base.

After that, the manager walked over to umpire, who was serving as the home-base umpire from the third-base dugout, and they spoke for about two minutes.
