With a hat tip to Reddit, here’s a photo of a young Masahiro Tanaka meeting Hideki Matsui at the old Yankee Stadium (click for larger). It’s from 2006, when the Japanese high school All-Star team was touring the United States. There are some other (non-Yankees-related) photos in this stream.
Now the Yankees just have to figure out how to get Tanaka to take their many millions of dollars to pitch in the new Yankee Stadium.
