It's getting close to that time where MLB teams start discussing internal moves within the organization that could make their big league roster better. Down on the farm, certain prospects are forcing the issue and doing what I call "knocking down the door" to the big leagues.
In some cases, getting through that door is as simple as playing well over a period of a few weeks while the major league roster gets limited production out of that position.
Kevin Gausman, who made his big league debut Thursday for the Orioles, didn't force a good pitcher out of the rotation. He had terrific numbers in Double-A (3.11 ERA, 46.1 IP, 5 BB, 49 K), but the O's simply had a huge need to fill and made the easy call to go with one of the best pitching prospects in the game.
Then there are the prospects doing everything they can to kick the door down, but there's a veteran player—often established in the majors and with a guaranteed salary—standing in their way.
Instead of gambling on an unproven player and pushing a veteran to the bench or off the roster, it could make more sense to open up a spot with a trade.
The Braves opened a spot for pitching prospect Julio Teheran in their rotation by trading Tommy Hanson before the season. The Diamondbacks traded away two outfielders, Justin Upton and Chris Young, ensuring that center field prospect Adam Eaton would have regular playing time.
Here are eight prospects who could be forcing a trade of the veteran currently blocking their path to the majors.
