Around the System–Catchers

Lehigh Valley

Andrew Knapp, 24, Phils 2nd round pick in 2013; .245/.339/.451 in 116PA; 5HR 17RBI; 12%BB/22%K rates; .286 vs LHP; .224 vs RHP; .220 in May; 27 games caught with 5 errors (.974); 6 passed balls; 3/17 (18%); Knapp has been very streaky with the bat and his defense needs drastic improvement.

Logan Moore, 25, Phils 9th round pick in 2011; .239/.329/.338 in 81PA between Reading and Lehigh Valley; 1HR 7RBI; 12%BB/21%K rates; 23 games caught with 1 error (.994); 0 passed balls; 11/24 CS (46%). Moore’s production with the bat remains very little however, he is a plus defensive catcher and is doing a very good job calling games.


Jorge Alfaro, 22, Acquired from Texas in 2015; .362/.375/.580 in 70PA; 2HR 15RBI; 2%BB/20%K rates; .500 vs LHP;.344 vs RHP; .212 in May; 16 games caught without an error; 1 passed ball; 5/11CS (45%); Alfaro has done a generally outstanding job when healthy.  He missed about three weeks with an oblique injury

Joel Fisher, 23, Phils 24th round pick in 2015; Fisher was hitting .188 in 16AB with Lakewood before his promotion to Reading; 6 games caught without an error or passed ball; 6/13 CS (46%)


Gabriel Lino, 23, Acquired from Baltimore in 2013; .200/.273/.288 in 87PA; 1HR 5RBI; 8%BB/21%K rates; .083 vs LHP; .221 vs RHP; .355 in May; 23 games caught with 2 errors (.990); 4 passed balls; 11/33 CS(33%); Lino has been relegated to organizational catcher, which seems to be appropriate based on production.

Chace Numata, 23, Phils 14th round pick in 2010; .254/.329/.333 in 70PA; 0HR 4RBI; 1SB; 10%BB/15%K ; 250 vs LHP; .255 vs RHP; 16 games caught with 1 error (.994); 3 passed balls; 5/18 CS (28%); Numata has received fairly regular playing time and has done a good job backing up Lino.


Deivi Gruillon, 20, Signed as a free agent in 2012; 260/.351/.400 in 56PA: 1HR 5RBI; 11%BB/23%K; .207 in May; 13 games caught with 3 errors (.975); 5 passed balls; 4/14 CS (29%); Gruillon missed almost a full month injured, and his defense which by all accounts is his forte has been a notch or two below expectations early on.

Austin Bossart, 22, Phils 14th round pick in 2015; .259/.348/.397; 1HR 8RBI; 9%BB/8%K rates; 18 games caught with 1 error (.995); 1 passed ball; 8/36 CS(22%); Bossart has done a good job receiving more regular playing time than expected because of Gruillon’s injury.

  1. This is all about Alfaro and Knapp, although Moore could very well be a good MLB defensive catcher. Knapp needs to get his act together, and I do think he will. I wonder if he’ll ever be able to learn a different position, because realistically, Alfaro is the guy and will jump Knapp when ready.

    At one point I thought Lino could be a MLB backup, but it seems he has regressed into org guy. Slightly disappointing, but not a big deal. The world needs Clement Alvarez types

  2. For all of the good things happening in the Phillies system, the one dark spot is at the catcher position which looked like an area of strength just a year ago.

    Knapp’s defense has regressed to the point it looks like he’s not going to stick at the position
    Lino has turned into organizational filler
    Gruillon hasn’t show any advancement offensively and regression defensively..

    Alfaro appears to be the only prospect left at the position at this point..

    1. your Grullon point is extremely incorrect. His offensive numbers have improved substantially so far this year (SSS) across the board. You couldn’t be more wrong about that. Heres his offensive numbers:

      and where are u getting this info that he has regressed defensively? I’m curious, because I hadn’t read anything similar.

      As far as Lino, he was always org filler.

      You’re writing Knapp off pretty quickly. But even if he does move off catcher, that’s the name of the game in developing players. Guys fall off before they reach the majors. Did you think the Phillies really had 4 starting quality major league catchers in their system at once? Theres a reasonable chance none of them make it. I think a lot of teams would still like to have Knapp, Alfaro, and Grullon in their systems…

      1. ‘I think a lot of teams would still like to have Knapp, Alfaro, and Grullon in their systems…’
        Cleveland Indians for one.

      2. I got the info about Gruillon’s defense from Gregg’s write-up in this thread. Did you read it?

        As for his offense, I should have stated that he hadn’t shown signs of improvement going into 2016. His 53 at bats in 2016 isn’t enough of a sample to make a judgement either way. His 2016 BABIP is much higher than it had been so maybe it’s luck, maybe it’s improvement. Either way, at 20, he’s got time.

        In the case of Knapp, his bat was always ahead of his glove and his glove isn’t getting better. If he needs to move positions, then he becomes an average at best 1b prospect. But since we are talking about catchers, him moving to another position doesn’t help the organization at catcher.

        Did I think that Phillies had 4 ML catchers in the system at once, well yes, a year ago, it appeared they MIGHT have 4 guys with the potential to be big league catchers, at least in a back-up role.

        That number looks like it is now down to 2 with Alfaro and Gruillon.

        1. Oh I thought you meant that you had actually read somewhere credible that Grullons defense had regressed. Not the above write up from a guy who’s scouting the stat line. My bad.

          And again, you’re just writing Knapp off. Its interesting, this season so far is not a big enough sample size to make a judgment either way on Grullon, but it is a big enough sample size to completely write off Andrew Knapp as a catcher. Got it. Thanks for clearing that up for us….

          1. Wow that sounds like you are taking a shot at Gregg.

            Note to Gregg your write-ups have no credibility according to Tommy!

            1. By credible I mean someone that has or does watch Grullon play everyday since we are talking about regression, which can only be measured over a period of time. I could be wrong, but Gregg is the resident IronPigs writer, meaning he does not see Grullon play everyday, and hence means he is scouting the stat line. Not a shot at anyone, just reality…

      3. Yeah I have changed my view of Knapp. I really let last yr get my hopes up with him. He’ll be a nice piece on the major league roster at some point (or a nice trade piece down the road) but time will tell what his role will be. Still love his bat and no rush with his development behind the dish.

        Alfaro, on the other hand should do well to be challenged at the next level and fairly soon. He and Crawford are types more likely to drone along when the game comes easier for them.

        1. All evidence points to him just being an absolute butcher behind the plate. That’s not going to translate to a regular catcher unless you’re providing offensive value in line with Yogi Berra. Knapp seems to be headed for a position change, if his bat can translate to a new position.

  3. I wouldn’t mind if Knapp and Alfaro both spent a year in their respective leagues, working on defense. I understand a lot of people want Alfaro to move up soon due to his bat, but his BABIP is immense (.426). That’s a long way from sustainable.

    We have to avoid the idea that good batting average = ready to move up. His BB% is 1.4%, and he has 2 HR, which means most of his ISO is from doubles. He could be really good, but we need to be patient.

  4. I think people have long over estimated Grullon’s defense because of the positive opinion of a previous administrator of this site. We were always told that his defense was advanced. Not that he had the tools to be advanced defensively like Alfaro but that it was already advanced. Yet every year he has double digit errors and passed balls, and under 30% CS despite a cannon arm and impressive pop times.

    1. Saw Grullon twice last year and while he was definitely impressive behind the plate he looked like he’d never swung a bat before in his life. “Overmatched” doesn’t even scratch the surface of what he was on offense.

  5. I’ve always been a fan of Logan Moore. I think that he can have a solid ML career, similar to Jeff Mathis, who has a career average under .200 but has managed to play 12 seasons in the big leagues.

  6. It will be interesting to see how Fisher does when given the opportunity in Reading.
