Sorry, do not want to be in any way argumentative, but I still think it's Roger Craig. Perhaps he was there with the club (wherever these were taken) in spring training or something. Not sure when exactly he was in Korea. Or perhaps some(?) of the photos were taken a different year?
That signature brush cut, the tiny little mouth, the chin, the ears, etc. The 'surprise' flash seemingly opened his eyes a little more than usual, but it's pretty close to what is seen on his 1957 card.
