No. 1: Mason Williams, Outfielder
69 G, .304/.359/.489, 84 H, 19 2B, 4 3B, 8 HR, 28 RBI, 21 BB, 33 K, 19 SB (Low A)
22 G, .277/.302/.422, 23 H, 3 2B, 3 HR, 7 RBI, 3 BB, 14 K, 1 SB (High A)
Williams is the best athlete in the system with his solid, yet still raw, five-tool skill set. He continued to translate those raw skills into results last season, showing better plate discipline and pitch recognition. He is not likely to hit for a lot of power, as his body is not very big and his swing is tailored more towards making contact.
That said, if Williams continues to improve his pitch selection then he could turn into a player who hits 15 homers per season.
Defensively, Williams definitely has the speed and range to play center field. Yet he has an average throwing arm, and he does need to improve the routes that he takes to the ball if he wants to stay in center.
Williams also missed the last month of the 2012 season with a torn labrum.
No. 2: Gary Sanchez, Catcher
68 G, .297/.353/.517, 78 H, 19 2B, 13 HR, 56 RBI, 11 SB, 22 BB, 65 K (Low A)
48 G, 279/.330/.436, 48 H, 10 2B, 1 3B, 5 HR, 29 RBI, 4 SB, 10 BB, 41 K (High A)
Sanchez's biggest question mark is whether or not he can stay behind the plate. This is not a Jesus Montero situation, where Sanchez will be too big for the position, but his defense comes and goes. He had 18 passed balls last season (via Baseball Reference).
Considering his age and throwing arm, which is fantastic, Sanchez will be given the benefit of the doubt.
And when you look at his bat, it is hard not to love what Sanchez could turn into. He is already showing power in games, and he has shown himself to be a good baserunner, despite not having a lot of speed. He stole 15 bases last season.
Sanchez's swing is very good, as he loads quickly and gets the bat through the zone in a hurry. He does swing and miss a little more than you would like, but again, he's just 20 years old and played in High A last season.
No. 3: Slade Heathcott, Outfielder
5 G, .235/.409/.353, 4 H, 2 2B, 2 RBI, 5 BB, 4 K, 2 SB (Rookie)
60 G, .307/.378/.470, 66 H, 16 2B, 2 3B, 5 HR, 27 RBI, 20 BB, 66 K, 17 SB (High A)
Heathcott's rise through the system has been a slow climb, as he has battled serious personal problems that included alcohol abuse. Those personal demons have kept the world from seeing what he is capable of doing on the field—though that is obviously low on the totem pole in the grand scheme of things.
On the field, Heathcott continues to make strides. He still has to prove that he can play an entire season, as he has never had more than 298 at-bats in a season since being drafted.
An incredible athlete, Heathcott can run, hit for power and is more than capable of playing center field in the future. He does need to work on his swing, as his pitch recognition is not very good and he strikes outs too much (231 times in 755 career at-bats) to project as an average hitter.
No. 4: Tyler Austin, Outfielder
70 G, .320/.405/.598, 85 H, 22 2B, 5 3B, 14 HR, 54 RBI, 37 BB, 68 K, 17 SB (Low A)
2 G, .500/.571/1.000, 3 H, 1 HR, 2 RBI, 1 BB, 1 K (Rookie)
36 G, .321/.385/.478, 43 H, 13 2B, 1 3B, 2 HR, 23 RBI, 12 BB, 28 K 6, SB (High A)
2 G, .286/.375/.286, 2 H, 1 RBI, 1 BB, 1 K (Double A)
Austin has succeeded at every level that he has played at as a professional. That is both a blessing and a curse, because you want to see what a young player will do when he is forced to make adjustments.
Because he uses a contact approach to hitting, Austin is going to have a very limited power ceiling. Yet he does have a great eye and tremendous bat speed to be a plus hitter.
Austin will continue to develop as a right fielder, which limits his ceiling because there isn't enough power in his bat for this position. But if he can hit .300 with a great on-base percentage and above-average defense, the team will be able to live with some limitations in the bat.
No. 5 Ty Hensley
5 G (4 starts), 1-2, 3.00 ERA, 12 IP, 8 H, 8 R (4 ER), 1 HR, 7 BB, 14 K
After the first four players on the list, it really is a crapshoot regarding who you can put at No. 5. If you believe in the upside of Jose Campos, and that he will stay healthy, he could be at this spot. Manny Bauelos still has upside and is young, but too many questions about his arm make it hard to put him in the top 5.
Ultimately, Hensley gets the nod, even though he has very limited professional experience after being drafted by the Yankees in the first round of last June's draft. But even he has injury concerns, as he was forced to sign a below-slot deal due to shoulder abnormalities (h/t Jim Callis of Baseball America).
Hensley has a great pitcher's frame, at 6'4", 220 pounds, and an above-average fastball. Jonathan Mayo of MLB.com wrote that his offspeed stuff needs a lot of work, and in the case of his changeup, he will need to begin throwing it more in order to be a starter.
The ceiling for Hensley as a No. 3 starter is there. It is just a matter of getting experience and showing what he can do before we have any idea what he will become.
