I'm going to do my own under-20 (baseball age -- as of July 1 ) prospect list by level for Phils players. (note-Cornelius Randolph is the youngest player on Reading, at baseball 21). I'll add DSL later if andyb doesn't beat me to it.
Sixto Sanchez(RHP)-A+: Injured much of the year, consensus #1 prospect in the system, was only 19 on July 1. Great velocity on the fastball, reportedly healthy now in CLW, throwing BP and simulated games. I might be tempted to bring him back for the FSL playoffs. Sixto is younger than any pitcher on the Lakewood roster.
Simon Muzziotti(OF,LH)-B-: Young for Lakewood has struggled folloiwing an early trip to the DL this season. Mediocre numbers at Lakewood with no power and few walks. Seems likely to repeat Lakewood to me.
Jhailyn Ortiz(OF, RH)-A-: Disappointing year after a dominant performance at Williamsport last year. Had one hot streak, but was having difficulty making contact the rest of the time. Power still there with a .150 ISO. I'd bump him to CLW next year.
Ethan Lindow(LHP)-B+: Regular starter with a mid-2 ERA and about 8Ks/9IP. Will make most Philies' top-30 lists I would think. Lakewood next season. Might move him there for the playoffs if I were the Phils.
Francisco Morales(RHP)-A: An under -the-radar prospect, a 6'4" starter who throws hard and has 57Ks in 45 IPs. Needs to sharpen his control in Lakewood next year.
Manuel Silva(LHP)-B+: A strikeout/IP with a 3-ish ERA this season. The rail-thin lefty is a bit wild and gives up too many HRs. Will be in Lakewood next year.
Raphael Marchan(C,SW)-B+: High BA catcher needs to be more patient at the plate with his current lack of power. Has a good defensive rep.
Brayan Gonzalez(2B,SW)-C: Didn't make the hoped-for jump in performance this season coming off of a good stateside debut in GCL. Might repeat WMPT next season.
Johnathan Guzman(SS,RH)-B-: Another player who disappointed with the bat this season, but played mostly at age 18 this year, and was good defensively at an important position.
Ben Pelletier(OF,RH)-A: Another under-the-radar prospect who started slowly after a spring injury but is ripping the ball now. 880 OPS in July and August.
GCL (only the top performers listed, playing at 18 or younger baseball age):
Dominick Pipkin(RHP)-B:High-bonus draftee with a mid-3 ERA and not many strikeouts. Phils really limited his innings this season, might repeat GCL or go to WMPT next year.
Victor Santos(RHP)-A: What can you say about 65Ks and 4 BBs? control artist will need to add some velocity to move up.
Ben Brown(RHP)-A-:62Ks in 49IP with decent control. A nice season for the NYHS prospect who seems to be tiring a bit late in the season.
Kyle Glogoski(RHP)-B+:The New Zealand native had a nice debut season with 47 Ks in 39 IP and good control. Needs a bit more experience on the mound to rate higher.
Juan Aparicio(C)-A-:High average catcher with a lot of power, but needs to take more walks (only 4 this season). His BA took a 130 point jump this year, let's hope it was real. Catchers sometimes move slowly because they are working hard on defense, so expect Aparicio in WMPT next year.
Abrahan Gutierrez(C,RH)-B+: A solid hitting catcher who hits a lot of balls on the ground. The former Brave (lost due to MLB penalties) played well for the Phils overall repeating the GCL. I'm guessing he starts at Lakewood next year.
Logan O'Hoppe(C,RH)-A 950 OPS catcher--what's to complain about? Seems a bit behind the other GCL catchers on defense (did a lot of DHing this season). Should walk a bit more than he does, which may help his power, too.
Luis Garcia(SS,SW)-A+:A solid defensive SS who can really hit with power and patience. Should be a top 5 prospect for the Phils this off-season. Stole 10 bases this season, albeit in 18 attempts. 900 OPS.
DJ Stewart(3B,RH)-B:Played a full season in GCL after getting his feet wet last year. Flier signing has patience but has yet to show game power.
Nicolas Torres(2B,RH)-A-:Good average, little power or patience now. Has hit well for average in both of his minor league seasons, and got a significant bonus.
Logan Simmons(SS,RH)-A:He's an interesting comparison to Torres--much lower average but takes walks and hits for power, posting a 750 OPS. I think he'll go to Lakewood next year.
Carlos De La Cruz(OF,RH)-A-:6'8" OF still moves a bit awkwardly, but he can seriously hit for a kid in GCL. An 830 OPS with decent patience to go with his power. Might make Lakewood next year; hope he can stay in RF.
