The first thing that strikes me when I look at this card is "did I run spell-check?" The second is that the 1965 Rookies of the Year faced each other in the 1966 World Series. The Orioles swept the Dodgers in 4 games. Neither of these players were much of an impact. Lefebvre hit a solo home run in a 5-2 loss in game one. He had only one other hit in the series batting .167. Blefary had a hit in his first World Series at bat. It was a 2 out, bases empty single, he was stranded at first. He wouldn't get another hit in the series batting .077.
By 1973 both player would be out of the Major Leagues. Blefary would be playing in the minors for the Braves. Lefebvre would be in Japan playing for the Lotte Orions. He would become the first person to play on a team that won the American World Series and the Japanese World Series. He would also go on to manage several teams including the Chinese National Baseball Team in the Olympics and the 2006 World Baseball Classic.
