Will Shohei Ohtani Go 50-50? And If So, When?

There are numerous nice baseball storylines to maintain tabs on this month. Aaron Decide is on one more historic tear. Bobby Witt Jr. and the Royals are crashing the playoff get together. The Brewers and Guardians are exhibiting the league that you just overlook the Central divisions at your personal peril. However it all pales compared to Shohei Ohtani’s pursuit of fifty residence runs and 50 stolen bases, at the least for me.

The 50-50 membership doesn’t have any members. Ohtani is alone within the 44-44 membership, the very best present rung he’s attained, and it doesn’t seem like anybody else can be becoming a member of him anytime quickly. Ohtani himself in all probability gained’t repeat this; it is a profession excessive in steals by a mile, and I don’t suppose it’s a coincidence that it’s taking place in a season when he isn’t pitching. Subsequent 12 months, I feel that he’ll rein himself in additional, however proper now, we’re seeing what it appears like when a quick participant decides that they actually do need to steal all of the bases they’ll. After all, it helps that he’s additionally some of the highly effective hitters within the recreation – each to intention for the 50-50 goal and since opposing pitchers stroll him very often.

Will he make it? I’m unsure, however fortunately I’ve a way that lets me estimate the chances. When Decide hit 62 homers two years in the past, I constructed a little instrument to estimate the probability of him hitting that milestone, in addition to the probabilities of it taking place in any specific recreation. That technique works fairly effectively typically, so I redid it with a couple of modifications to deal with the truth that we’re two counting statistics as a substitute of only one. I’ll begin by reviewing the methodology, although when you’re not into that, there are some tables down beneath that offers you an thought of when and the place Ohtani may hit (or run into) this momentous milestone.

I began with our Depth Charts projection for Ohtani’s residence run charge the remainder of the way in which. That’s primarily based on impartial opposition, so I additionally took opposing pitching staffs under consideration, in addition to park elements for lefty residence run charge. Lefties hit extra homers in Dodger Stadium (12 remaining video games) than in Truist Park (three remaining video games), and batters hit extra homers in opposition to the Rockies (six remaining video games) than the Padres (three remaining video games). I used park issue and opposition power to switch Ohtani’s baseline residence run charge and create a singular residence run charge for every remaining recreation. I then picked a random variety of plate appearances (4, 5, or six, with 5 essentially the most frequent) for every recreation.

The Dodgers will doubtless give Ohtani at the least someday off the remainder of the season, so I constructed that into my calculations. I don’t know which day it will likely be particularly, so I had my simulation choose a random day in Los Angeles’ upcoming 10-games-in-10-days stretch. I additionally made a slight adjustment to higher mirror actuality: As an alternative of getting a static residence run charge, Ohtani’s true residence run expertise fluctuates randomly round his projected charge, which implies that generally he hits residence runs 8% of the time on this simulation, whereas generally it’s nearer to five%.

Projecting the probabilities of him hitting 50 homers is fairly simple that method. The distribution of attainable video games he’ll do it in appears like this:

That’s not the query we’re asking, although. Fifty homers is cool however hardly unparalleled. We’re attempting to find 50-50 seasons. To do this, I added a second counter for stolen bases. I didn’t use park and group elements right here, I simply took a projected steal charge for Ohtani and utilized it to the remaining video games. I did make one modification, although. Clearly Ohtani can’t steal a base if he hits a homer, so I subtracted every recreation’s homer whole from its plate look whole for the stake of modeling stolen bases. In different phrases, if he batted 5 instances and hit two homers, I’d solely simulate an opportunity of a steal within the remaining three PAs.

From there, issues are fairly simple. When sim-Ohtani hits his fiftieth homer, the simulation checks to see if he already has 50 steals. If he does, that recreation is his 50-50 day. If he doesn’t, then the simulation for stolen bases for that day runs. On the day of his fiftieth steal, the identical factor occurs in reverse – if he already has 50 homers, then that’s the day he hits 50-50. If not, the simulation retains going. On this method, we will get the joint odds of the 2 issues taking place as a substitute of the impartial odds of every one.

The sum likelihood of Ohtani hitting each totals is round 56%. That makes intuitive sense to me – we’re projecting him for 50 homers and 51 steals, and I feel the remaining parks and opponents bias the house run whole upward. The joint likelihood can’t be rather more than 50%, however I don’t suppose it must be a lot much less both, on condition that he’s fairly prone to hit the steals whole. I peg these odds at round 84%. That’s greater than you’d count on from our projections, however numerous stolen base charge comes right down to intent, and I’m pretty positive that Ohtani intends to steal 50 bases this 12 months, so his go charge is probably going greater than our naive projections.

The distribution of days the place Ohtani may go 50-50 appears like this:

In different phrases, when you can solely go to 1 recreation and need the perfect likelihood of seeing a record-setting occasion, you must go to the primary recreation of the ultimate sequence of the 12 months in Colorado. If you happen to solely need to go to 1 sequence, it must be that one. Ohtani might definitely hit each totals earlier, but it surely’s troublesome on condition that doing extra of 1 occasion implies much less of the opposite.

That’s to not say there’s no likelihood of an early milestone. There’s a roughly 7% likelihood that Ohtani hits each plateaus earlier than the ultimate homestand of the 12 months begins on September 20, and an additional 30% likelihood of him hitting it throughout these six residence video games. If I have been attempting to find a particular time to go see him, I’d choose that one: at residence, in opposition to first a foul pitching employees after which a division rival.

One factor price noting is that these odds can change quick. If Ohtani hits a homer and steals a base tomorrow night time, the chances shoot up into the mid-70s instantly. The more than likely time to see the 50-50 recreation strikes as much as the final recreation of the house Colorado sequence, with the stretch in opposition to the Padres not far behind. Whenever you’re coping with such uncommon occasions – nobody hits a homer each night time – a binge of a day or two can have a giant impact.

Is that this gospel? Clearly not – it’s a easy simulation meant to offer you a tough thought, not me predicting the long run with good readability. However that tough thought is fairly cool. Ohtani may do the beforehand unthinkable and publish the power-speed season that has been lengthy rumored however by no means achieved. I completely need to know when that may be – and pinpointing it for enjoyable is correct up my alley.
