The strangest moment of Tim Tebow's first game against major leaguers actually came afterward, when Tebow tried to explain the second-strangest moment of his first game against major leaguers:
About straying into the Red Sox's on-deck circle before his first at-bat, Tim Tebow said, "I thought you walk around [to the first-base side of the field] because you're a left-hander. I found out you don't do that."
This answer makes even less sense than the act he was asked about. Tebow has played a lot of baseball -- including a full season in the Arizona Fall League -- and presumably has watched even more, and this isn't how any baseball is played anywhere.
