Moncada's contract was selected from Double-A Portland on Friday.
EDGE Analysis
It was announced that Moncada would be getting the call a couple days ago, and it was fairly apparent that this was coming a couple weeks ago when he started playing third base with Portland (he is a second baseman by trade). He has some swing and miss in his game (30.9 percent K-rate at Double-A) and he has struggled to hit lefties (.167 average in 36 at-bats), but he is still quite easily the top prospect in baseball for fantasy purposes. He has all the makings of a five-category contributor, with the power starting to catch up to the speed, and he should occupy a prominent spot in the Red Sox's order for years to come. It is unclear how many days per week he will play initially, but Boston's other options at the hot corner have been horrendous in the second half, so there are plenty of at-bats up for grabs. Based on his upside, Moncada should be rostered in the vast majority of formats.
