Clawsgirl, I was planning to work my way down through the levels, but since you asked I'll speculate...
A-:
LF-Ben Peletier
RF-Ben Aklinski
CF-Julio Francisco/Yerwyn Trejo/Keudy Bocio (my order of preference--Bocio is the most experienced, Francisco the youngest with the highest ceiling, and Trejo played really well in rookie league last year at an advanced age)
1B-Matt Kroon (other choices would have included Edwin Rodriguez and Stoney O'Brien, but both were released. Jake Holmes might play here...)
2B-Nic Torres (if they go young), Brayan Gonzalez if they don't. Seth Lancaster utility.
SS-Luis Garcia (young), Jonathan Guzman (older)
3B-Bohm probably goes to CLW, so Jake Holmes (who may play other positions), or Luke Miller
C--Rafael Marchan (probably WMPT MVP last year), Jesse Wilkening
This is a solid offensive team which may get strangled by the Lakewood park and the Sally League's pitching bias.
Rotation:
Francisco Morales
Colton Eastman
Ethan Lindow*
James McArthur
Jhordany Mezquita*
Manuel Silva*
Solid starting pitching. Relievers might be a struggle...
Juan Escoria has great stuff but was a starter last year. Keylan Kilgore was the primary closer for WMPT, Randy Alcantera and Rafael Carvajal had solid ERAs. Austin Ross, Tyler Carr, and Abdallah Aris lead a bevy of other contenders. I don't think any reliever will jump from GCL.
We might have a little better idea if the Phils were providing Spring Minor League Game Reports as they have in the past...
