It appears Takumi Akiyama is on his way to joining the active roster since the Tigers need another starter with Naoto Tsuru moving into the bullpen. Not exactly sure when the start will come, but it will probably be sometime during the team's next 6-game stretch (that begins tomorrow).
The last Tiger pitcher drafted out of high school to pitch in his first year was Koji Okamoto on 10/6/2000 (vs Yakult).
On a side note (and tot that anyone probably cares), but I'm rooting for Akiyama because he's a graduate of my paternal grandmother's Alma mater, Saijo High School.
