While the big leaguers were mainly finishing up the first series of their new season Thursday, the minor leaguers started things up at the same time, and there are quite a few players whose progress fantasy owners should be following. While I continue to believe Texas Rangers prospect Jurickson Profar is so good that he will see enough time with the big club to make a serious impact, on Thursday he made his Triple-A debut for the Round Rock Express.

Profar made his mark, reaching base three times, stealing a base and dazzling defensively at shortstop. He's only 20 years old but seemingly ready for the Rangers right now should opportunity open up, and let's be clear, is not a must-own in ESPN standard, 10-team mixed formats. There are enough middle infielders to count on in a shallow league. In deeper formats, especially if you have deeper benches, I'd add him now. Each game that Mitch Moreland (0-for-11 so far) doesn't get a hit could make a promotion reality!

Of course, Profar wasn't the only potentially fantasy relevant player who enjoyed his Thursday Opening Day. Fantasy owners are always asking about which players they should be stashing away for later in the season. Here are several others who performed Thursday to keep an eye on, because not only do they seem ready for the big leagues, but it could be soon. These aren't necessarily the top prospects, but five on my mind this fine first Friday.
