Go Tigers!Noumi-san, I love you!
after a match, American baseball player Matt Murton interrupted an interview to hug his teammate Atsushi Noumi, jokingly saying in Japanese "Noumi-san, aishiteru" (I love you), to end an argument aroused by another statement released by Murton himself last June.
The girl in the picture is wearing Hanshin Tigers' (Murton and Noumi's team) uniform.
