The guidelines that built this team are pretty fluid, but in a general sense, a player must have significantly enhanced his dynasty profile to qualify. 

Catcher

Orioles C Samuel Basallo has slowed down some since a steamy start but is still slashing .299/.340/.489 with four home runs and two steals as an 18-year-old in Low-A. He looks solid behind the plate, too, especially for a 6’3” teenager. 

Honorable Mentions: Dodgers C Thayron Liranzo. One way to identify a player like this is the ratio of relevance to league-size is changing in a hurry on the fly. Though I’ve added him elsewhere, I’ve mostly ignored Liranzo in my 15-teamer with 20 milb spots per team. This week, I saw his name in some tweets. On May 21, he hit his 10th and 11th home runs on the season. He’s slashing .310/.444/.690 in the month of May with 14 walks and 18 strikeouts in 16 games. Still just a catching prospect in Low-A, but he’ll be off the board in most leagues before long.
