Now comes the really interesting decision.
In the traditional view of player development, Hamilton would spend the entire 2013 season -- or most of the season -- at Triple-A. Even that would be pushing him, because he has played just 50 games above Class A.
There are two other factors playing into Jocketty's decision. One is the success that Mike Trout, Bryce Harper and Manny Machado had in 2012.
They were all rushed to the Major Leagues. They all succeeded, too. And they're all younger than Billy Hamilton.
Harper and Trout played 21 and 20 games, respectively, at Triple-A. Machado played 109 games at Double-A and made the jump to the Major Leagues without a stop in Triple-A.
What they all have in common is that they were fast-tracked to the Major Leagues, and they all held their own.
All of them struggled at times. But Harper and Machado helped their teams to the playoffs, and Trout will finish first or second in the American League Most Valuable Player Award balloting.
"Those guys are extremely good athletes and players," Jocketty said. "Certain guys can do it, and Billy might be one. He's a talented player with great instincts."
