Very interesting conversations ongoing in the Jason Heyward Community Projection thread. I'll tally up the results Friday. In the meantime, here is another young player from the NL East sure to generate some intriguing projections as well as discussion: Fernando Martinez.
As with Heyward, project the following numbers for Martinez
Batting average (make sure numbers are right)
I will calculate OBP and SLG for you.
Whether he makes the major league roster out of spring training or not will naturally be reflected in the number of at-bats and games you project. You might also consider the injury factor given Martinez' history of health issues.
