Around the System–Starting Pitching, Lakewood, Williamsport, GCL

A look at Starting Pitching at the lower levels of the organization.


Ranfi Casimiro, 22, Signed as a free agent in 2010; 22 starts, 4-9 with a 5.21ERA; 107IP 116H 55BB 77K; 11HR allowed; 1.34 GO/AO; .269; 1.60 WHIP; 4.6BB/6.5K per 9; .265 vs. LH, .273 vs. RH; .299 with RISP; 2-4 with a 5.48ERA in 9 starts post all star game.  Pretty consistent mediocrity for Casimiro all season.

Tyler Viza, 19, Phils 32nd round pick in 2013; 21 starts; 3-14 with a 5.27ERA; 110IP 151H 21BB 63K; 8HR allowed; 1.7BB/5.1K per 9; 1.14 GO/AO; .322 opp avg; 1.56 WHIP; .307 vs. LH, .338 vs. RH, .271 with RISP; I have no idea why the Phils stuck Viza in Lakewood as a 19 year old all year.  He was hit around consistently and would have been better served to gain some confidence in Williamsport mid season

Jon Prosinski, 23, Phils 10th round pick in 2013; 22 starts, 4-8 with a 5.22ERA between Clearwater and Lakewood; 120.2IP 152H 27BB 68H 8HR allowed; 1.48 WHIP; 2.0BB/5.1K per 9; 1.58 GO/AO; .305 opp. avg; For Lakewood: 13 starts, 4-4 with a 4.33 ERA, 1.40 WHIP.  Generally a very disappointing season for Prosinski where he was demoted mid season and been slightly above average for Lakewood.

Matt Imhof, 20, Phils 2nd round pick in 2014; 7 starts; 1-1 with a 2.25 ERA between GCL, Williamsport and Lakewood; 28IP 23H 6BB 27K; 1.04 GO/AO; .232 opp avg; 1.04 WHIP; 1.9BB/8.7K per 9; Imhof has given no reason to be anything but excited by his performance thus far.

Yoel Mecias, 20, Signed as a free agent in 2011; 8 starts, 2-2 with a 3.16ERA between GCL and Lakewood; 37IP 31H 14BB 21K; 0.85 GO/AO; .233 opp avg; 1.22 WHIP; 3.4BB/5.1K per 9; Just off of Tommy John surgery, Mecias does not have his “stuff” back to where it was pre injury but plenty to be encouraged about.  On track to be in the Clearwater rotation in 2015.

Yacksel Rios, 21, SIgned as a free agent in 2010; 31 games (10 starts); 5-1 with a 3.35 ERA; 1 save; 88.2IP 79H 35BB 66K, 6HR allowed; 1.25 GO/AO; .234 opp avg; 1.28 WHIP; 3.6BB/6.7K per 9; 4-1 with a 3.55 ERA and 1.36 WHIP as a starter.  Very good season for Rios without being overpowering.

DL: Drew Anderson


Alejandro Arteaga, 20, Signed as a free agent in 2010; 19 starts; 4-12 with a 6.65ERA between Lakewood and WIlliamsport; ; 94.2IP 142H 19BB 56K; 11HR allowed; 1.09 GO/AO; .353 opp avg; 1.70 WHIP; 1.8bb/5.3K per 9; For Williamsport: 10 starts, 1-6 with a 4.85 ERA; .323 opp avg; 1.46 WHIP.  Absolutely brutal in Lakewood prior to demotion; Slightly less brutal in Williamsport

Mitch Guellar, 20, Phils 1st round pick in 2012; 9 starts, 5-2 with a 2.93ERA; 46IP 41H 20BB 23K; 1HR allowed; 0.65 GO/AO; .247 opp avg; 1.32 WHIP; 3.9BB/4.5K per 9; .254 vs. LHH, .242 vs. RHH, .222 with RISP; 4-1 with a 2.18ERA since July 1.  Guellar has turned it around as of late, showing he knows how to pitch without overpowering stuff.  Named a NYPL All Star, he is very close to a lock to land in the 2015 Lakewood rotation.

David Whitehead, 22, Phils 34th round pick in 2013; 10 starts, 3-3 with a 2.68ERA; 57IP 57H 8BB 36K; 1HR allowed; 1.34 GO/AO; .260 opp avg; 1.14 WHIP; 1.3BB/5.7K per 9; .259 vs. LHH, .261 vs. RHH, .320 with RISP; Coming off Tommy John surgery, Whitehead has been very good and was named a NYPL All Star.  If he keeps the pace for the remainder of ’13, he is a candidate for a double jump into the Clearwater rotation.

Feliberto Sanchez, 20, Signed as a free agent in 2011; 10 games (7 starts); 2-6 with a 6.00ERA; 39IP 47H 19BB 20K; 0.73 GO/AO; .309 opp avg; 1.69 WHIP; 4.4BB/4.6K per 9; .287 vs. LHH, .345 vs. RHH, .275 with RISP;  Sanchez has been crushed by right handed hitters which has been the primary cause of a pitching line that is very poor.

Ricardo Pinto, 20, Signed as a free agent in 2011; 6 starts, 0-3 with a 2.57ERA; 28IP 23H 10BB 27K; 2HR allowed; 0.91 GO/AO; .211 opp avg; 1.18 WHIP; 3.2BB/8.9K per 9; Very good thru 6 starts.

Brandon Leibrandt, 21, Phils 6th round pick in 2014; 9 games (7 starts) between GCL and Williamsport; 2-3 with a 2.89ERA: 43.2IP 31H 7BB 50K; 1HR allowed; 0.59 GO/AO; .205 opp avg; 4 Williamsport starts, .139 opp avg; 0.87 WHIP; 1.4BB/10.3K per 9.   I am excited by Leibrandt who has shown both good stuff without an overpowering fastball and that he knows how to pitch, like his dad did.


Sam McWilliams, 18, Phils   round pick in 2014 draft; 7 games (3 starts); 1-3 with a 7.16ERA; 16.1IP 21H 3BB 7K; 1.05 GO/AO; .339 opp avg; 1.47 WHIP; So far, it hasnt been real pretty.

Luis Morales, 21, Signed as a free agent in 2010; 8 starts, 2-2 with a 3.86ERA; 37.1IP 52H 6BB 27K; 1.55 WHIP; 1.4BB/6.5K per 9; Not awful, but not good.

Franklyn Kilome, 19, Signed as a free agent in 2013; 8 games, 5 starts; 2-0 with a 1.91ERA; 28.1IP 20H 8BB 17K; 1.38 GO/AO; .192 opp avg; 1 HR allowed; 0.99 WHIP; 2.5BB/5.4K per 9; Probably the most intriguing of the bunch, standing at 6’6.

Denton Keys, 19, Phils 11th round pick in 2013 draft; 8 games (4 starts); 2-1 with a 2.81ERA; 32IP 26H 8BB 22K; 1.24 GO/AO; .232 opp avg; 0HR allowed; 1.06 WHIP; 2.3BB/6.2K per 9.  A very nice line thus far for Keys, most specifically the absence of the HR ball and control.

Lewis Alezones, 18, SIgned as a free agent in 2012; 8 games (3 starts); 2-1 with a 3.00ERA: 24IP 19H 5BB 23K; 1.00 WHIP; 1.9BB/8.6K per 9; 1.50 GO/AO; .207 opp avg; Alezones has pitched very well.

  1. Rotations for next year for Clearwater and Lakewood.

    Clearwater-Imhoff,Mecias,Liebrandt,Watson and Whitehead

    Lakewood-Viza,Oliver,Gueller,Anderson and Thornhill

    That is unless they move Oliver to pen. I doubt they do that after a half a year,though.

    1. Not sure about Thornhill over Arteaga and Pinto. Both of those guys have touched 96 mph, and the Phillies’ placement of Arteaga at the beginning of the year indicates that they like him. Pinto has pitched very well.

    2. I’m not certain they will put Hanson in Reading so quickly. He is just coming back from almost a year on the DL. He will probably start in Clearwater.

  2. I know I’ve read a lot about Williamsport having pitchers ‘pitch to contact’, but some of those K/9 rates so atrocious.

  3. Wow , Viza has had a tough year , I dont know much about him how is his stuff and might it be time for a bullpen move ?

    1. He’s young for Lakewood so moving him to the bullpen doesn’t make a lot of sense to me. Plus, tonight he struck out 7, walked nobody and gave up 2 ER in 6 IP.

      No walks in his last 4 starts (21.1 IP)

      1. Because Viza is so young, it seems strange that the Phils would leave him in Lakewood to get beat up. 15 losses and counting. The kid must have an incredible makeup. Just hand him the ball and he’ll go out and see what happens. It doesn’t help that Lakewood’s lineup doesn’t bail anyone out. I want to see where they place him next year and how he handles it.

    2. PhoulBallz interview with Joe Jordan:
      Check it out today.

      -Tyler Viza (32nd round pick, 2013) is one of the youngest pitchers in the Class A South Atlantic League. He’s got the Lakewood record for losses. He’s 19 and it’s his first full season as a pro. Any concern about what sort of discouragement that claim to fame could bring for him? “No. He’s a strong minded kid. He gets it. He’s getting his innings, he’s (pitching) every six days. He’s gonna gain from this year. Obviously, some of it’s been his doing, some of it’s not scoring runs, but he’s alright.”

  4. I read here that Guellar does not have overpowering stuff. What’s the story with that? I thought when he was drafted he was supposed to have a power arm. Did he lose velocity or just not take the step forward that his projections suggested he would? Obviously, he has pitched okay this year, but if he’s a righty and he doesn’t throw hard, he has very limited upside.

    1. I remember reading here a few weeks back that he’s dialed down his fastball to work on his control and mechanics. Next step is to start letting it loose.
