At the start of the season, rookie defense was a story because of how poorly some rookies were playing. Two players in particular stood out: White Sox rookie first baseman Jose Abreu committed three errors in the first two weeks of the season, and Astros rookie outfielder George Springer, who was promoted in the middle of April, committed five errors in his first two weeks. Since those rough starts, both players have improved. In fact, Abreu has not committed an error since those first three, and Springer has just two errors since.
Abreu and Springer might be two of the most notable among this year's rookie class, but their early defensive struggles hardly speak for the rookie class as a whole. Because there are several guys who are proving that being new to the majors does not prevent a player from making a positive impact defensively over the course of the season. In fact, there are quite a few rookies who have been among the best defensive players in all of baseball this season.
