Springer profile; top 10 prospects

There's absolutely no debate as to which minor leaguer has had the most impressive statistical performance this season. Center fielder George Springer has Houston Astros fans and fantasy baseball owners dreaming of major league stardom. He's hitting .306/.415/.609 with 37 homers, 107 RBIs and 43 steals combined between Double- and Triple-A in his second full pro season.

He's the minors' first 30-homer/30-steal player since Oakland Athletics outfielder Grant Desme in 2009. If Springer can go deep three times this weekend, he'll become the only 40/40 man since the modern era of the minors began in 1962 and the first since outfielder Len Tucker slammed 51 homers and swiped 47 bags in the Class B Southwestern League in 1956.
