Derek Wallace suffered a hairline fracture of his right fibula in an automobile accident while at Pepperdine University. The injury cost him a month of pitching, but may have been the rest his arm needed, as he returned to the mound and put up a 0.71 ERA and 2-0 record to finish the season as College World Series Champions.
Wallace had a 5.40 ERA for Team USA in the 1999 Pan American Games, allowing Cuba 2 of their 5 runs (one of them unearned) in the Gold Medal loss for the US. The US still clinched a spot in the 2000 Olympics. Ten years earlier, Wallace was 0 for 1 as an outfielder for the US in the 1989 World Junior Championship. He was not the only player to appear in both 1989 WJC and the 1999 Pan Am Games; so did Charlie Greene.
