Mets 2020 projections: Pete Alonso

Today we kick off our eighth year of doing individual projections for the top players on the Mets. Like last season, these will be my own forecasts, not a group forecast like was done the first six years of the series. My hope is that everyone will weigh in on what they think the player will do in 2020. You’ll have more credibility later on about how you “knew” that Player X was going to have a breakout year if you say it before the game have started playing. Also, last year during the review part of our projections, a hat tip was given to the poster in the comments section who gave the best forecast. That will be the case again this year.

Just to state the obvious, these forecasts are pure projection and opinion on my part. There is no vigorous and non-biased systematic approach here. But you can get those computer projections from numerous systems out there. Speaking of the computer forecasts, ZiPS has already been released for the Mets, meaning we’ll have them from the start of the project. We’ll include numbers for any forecast system linked on the player’s B-R or FG page at the time our forecast is published.

To honor his amazing 53-homer season, we’ll start with Pete Alonso. Recall that it was far from a sure thing this time last year that Alonso would open the season with the big club. Many speculated that he would spend at least the first three weeks of the season in the minors so that the Mets would maintain an extra year of control. A few – not many – even speculated he would be kept down longer to avoid Super Two status.

But one thing that Brodie Van Wagenen made clear was that Alonso was going to be given a shot to win the job in Spring Training. And Alonso responded by posting a .352/.387/.620 line, with 4 HR in 75 PA. We’d like to think that he would have earned the job with those numbers. But it certainly didn’t hurt that two infielders – Todd Frazier and Jed Lowrie – opened the year on the IL, making it easy to bring the rookie north with the club for Opening Day.

Alonso hit right out of the gate, posting a 1.024 OPS the first month of the season. And outside of a brief lull right after the All-Star break, he pretty much hit all year long. One of the big questions about Alonso was if he could play first base at an acceptable level. And he ended up being much better than the scouting reports led us to believe. Alonso actually looked quite good scooping balls out of the dirt. Perhaps the biggest complaint with his defensive play was an over-eagerness to go after seemingly any ball hit on the right side of the infield. But there were improvement with that as the year went along and it’s possible even that won’t be an issue in 2020.

Defense certainly had the potential to limit the number of games Alonso played last season. But it’s unthinkable now after the offensive season he put up in 2019. He could be the equivalent of late-career Ryan Howard-level bad and he’d still be in the lineup every day.

So, how will Alonso fare offensively in 2020?

Looking at this Similar Batter through age 24 over at B-R, there are some interesting names, if not necessarily anyone who screams great comp. It’s certainly nice to see guys like Fred McGriff and Paul Goldschmidt and Albert Belle on his comp list. But it’s a little troubling to see old pal Ike Davis show up at the bottom of the list.

Instead, let’s look at the five top rookie HR players since integration before Alonso and see how they did in their rookie and sophomore seasons:

Aaron Judge
2017: 678 PA, .284/.422/.627, 52 HR, 114 RBIs
2018: 498 PA, .278/.392/.528, 27 HR, 67 RBIs

Mark McGwire
1987: 641 PA, .289/.370/.618, 49 HR, 118 RBIs
1988: 635 PA, .260/.352/.478, 32 HR, 99 RBIs

Cody Bellinger
2017: 548 PA, .267/.352/.581, 39 HR, 97 RBIs
2018: 632 PA, .260/.343/.470, 25 HR, 76 RBIs

Frank Robinson
1956: 667 PA, .290/.379/.558, 38 HR, 83 RBIs
1957: 677 PA, .322/.376/.529, 29 HR, 75 RBIs

Albert Pujols
2001: 676 PA, .329/.403/.610, 37 HR, 130 RBIs
2002: 675 PA, .314/.394/.561, 34 HR, 127 RBIs

First, that’s pretty awesome company for Alonso to be in. But as expected, all took a tumble from the previous season. Pujols’ “fall” was not as big as the others but he also was playing during the Silly Ball era. And we certainly need to keep the ball in mind when making the 2020 forecasts. Alonso was the right guy in the right moment last year, a guy with impressive power playing with a ball that was primed to leave the park. Will MLB feature the same ball in 2020?

Perhaps because of that, McGwire becomes the most interesting comp. His rookie season came in the big offensive year of 1987, the one where Wade Boggs went from 8 to 24 HR, a total he never approached again in his career. Meanwhile, in virtually the same amount of playing time in 1988, McGwire hit just 65% of the HR he did the year before.

So, what do the computer projections expect from Alonso in 2020? Here are the three we currently have available:

Marcel – 547 PA, .261/.353/.566, 39 HR, 90 RBIs
Steamer – 663 PA, .252/.343/.533, 44 HR, 104 RBIs
ZiPS – 620 PA, .254/.347/.551, 43 HR, 108 RBIs

Steamer is a tiny bit bearish, relatively, on the SLG forecast but otherwise these are pretty much in agreement on what to expect, which seems a little odd for a player with so little MLB experience.

To me the big question is how Alonso reacts when he doesn’t hit HR at the pace he did last season. Does he expand the strike zone in an effort to swing at any pitch he think he can club, regardless of if it’s a strike? Or does he confidently take walks and be content with good contact on pitcher’s pitches? My feeling is that there’s more room for AVG/OBP growth than the computers expect.

Alonso hit 27 HR at home and 26 on the road. But other than that, his numbers were all significantly better on the road. That’s not a huge surprise. But it’s certainly possible that Alonso can better his 2019 home BABIP of .217 in this upcoming season. With that thought in mind, here is my completely biased prediction for 2020:

675 PA
.275/.380/.560
38 HR
115 RBIs

You’ll have more credibility if you chime in now with what you think Alonso will do this year. These projections will run once or twice per week from now until the start of the regular season. Next up to undergo the forecast microscope will be Jacob deGrom.

    Hi Brian! I think Aloonso will do just as well this season similar to Pujous numbers. So much depends on who’s hitting behind him. I think he’ll have the patience and discipline to up his OBP and BA. So with that being said here goes

    PA 620
    BA .270/370/590
    HR 47
    RBI 126

    PA >550
    OPS .850 – .950
    HR 35 – 45
    RBI 90 – 100

    I’ll go low-end: .260/.352/.478, 32 HR, 99 RBIs.

    If Cespedes returns (which I expect considering what’s at stake for him financially) Alonso should have some additional protection in the lineup, so these numbers should rise, but here’s my stake for now.

    I think the balls are going to be the same in 2020, especially with many of them already made. Pete may lose some average but adjust and get even more production from the long ball.

    650 PA
    .240/.350/.580
    58 HR
    135 RBI

      Interesting that you think the ball will be just as lively. I’m guessing we see more balls like we saw in the playoffs.

      • BVac
        January 8, 2020 at 1:09 pm

        Only time will tell! I read somewhere that they are changing the production process for the 2021 season to help better regulate the ball, but until then who knows

    .271/.412/.536
    37 HR
    116 RBI

    I think we will see more walks this year.

    Happy New Year everybody; and let’s hope that in 2020 our Mets do make us happy. Everybody is assuming that Alonso stays healthy and is able to play nearly every day. I think that if he does start chasing balls out of the zone and his K’s go up alarmingly; that Beltran will sit him. I hope that’s not the case and that Pete will up his avg. If so, he’ll k 20 less (173) and walk 18 more (90).

    PA 580 HR 41 RBI 105 AVG .265 OBP 365 SLG 565 (930)

    Pete had an incredible year but I don’t expect him to duplicate it and the odds (and the ball) are against him. I hope he proves me wrong.

    I remember an interview Alonso did as a AA player, and that was that he wanted to be a complete hitter. I’ll go lower on the power, but higher on the other stuff:

    .292/.374/.592, 95 Rs, 115 RBIs, 33 HRs, 22% K Rate, 11% BB Rate

    Thoughout the minors, Alonso had a BABIP of well over .300, but last year it was .280. I’ll expect an increase in this again back up to over .300.

    Geez, I had not looked that closely or seen that his home BABIP was .217 in 2019. In looking more closely, he seemed to be a completely different hitter at home than on the road . . the ‘trying to impress’ syndrome working? If he can get the home stats to level out to his road stats from last year and keep the road stats in place, he can have a monster year. Obviously staying healthy is key. Also key – perhaps not to his HR or BA – but to Runs and RBI is where he hits in the lineup – Runs goes up if he hits 2nd, RBI goes up if he hits 3rd or 4th.

    My projection (assuming he hits 3rd or 4th) with Nimmo and McNeil (and Rosario?) in front of him and Conforto/Cespedes/Ramos behind him

    650 Plate Appearances
    .280 BA
    .390 OBP
    44 HRs
    90 Runs Scored
    130+ RBI
    44 Doubles
    2 Triples
    150 Ks (down from 183)
    100 BB
    .607 Slugging

    I eliminated the 21 HBP .. oddly 15 of the 21 were at home from the numbers, but for the sake of the calcs, each potential HBP will reduce the BB count.

    I would like to see a few less HBP, if only for the injury risk – 21 seems like a lot, and if he takes one in the wrong place (hand), it will obviously affect the seasons numbers.

    One last observation . .while his quest for 53 obviously panned out, his second half numbers were down across the board – is that because of the home run chasing, or would a few more breathers along the way help him out in August and September? He did not (and may never?) have the All Star game break.

  12. January 8, 2020 at 1:49 pm

    I say:

    635 PA
    .260/.335/.538
    45 HRs
    110 RBIs

  13. Mike W
    January 8, 2020 at 4:09 pm

    590 AB
    .262
    39 HR
    107 RBI
    88 Runs

  14. EG
    January 16, 2020 at 1:50 pm

    I think Alonso will provide the following:

    Games: 150
    AVG: .264
    OBP: .354
    SLG: .568
    OPS: .922
    HR: 42
    RBI: 104
