Joey Gallo is pretty amazing. This much has been established.
You can argue until you're blue in the face how he projects as a big-leaguer with his still-developing plate discipline and his inability to lay off pitches out of the zone, but one thing you can't argue is that the 20-year-old has prodigious power.
Gallo fell just one home run shy of Corpus Christi (Houston Astros) prospect Telvin Nash for leading the Texas League in home runs. Nash had 22; Gallo had 21. Gallo held on to the lead in the High-A Carolina League with 21 homers in 189 at-bats, leading the league on the entire season despite having not played there since June 6.
If he would've caught Nash, Gallo would've been the second player in baseball history to lead two separate minor leagues in home runs for an entire season, joining Fred Sington, who accomplished the feat in 1932.
Gallo probably won't have the opportunity again next season. He might start the season in Double-A Frisco, but he probably won't stay there too long before moving on up to Triple-A Round Rock.
