Rogers Centre Swaps Bats for Clubs: Nine Holes, 90 Minutes, and a Scoring System That Isn't in the Rulebook

In January, the floor of Rogers Centre — where the Toronto Blue Jays play — will no longer host baseball. In its place: nine golf holes, a 90-minute round, and a scoring system that has never appeared in any book of golf rules. Players tee off from the 200 Level stands and finish at the 500 Level. A ball that lands on the green counts as par; a miss is a bogey; inside the inner pin circle is a birdie; and a hole-in-one is called by baseball's own word — a home run. That was the first number that made me stop. Not because it was strange, but because it could not be compared with any metric I have used in seventeen years of reading sports tables. No Strokes Gained. No ShotLink. No OWGR. And I begin with that very gap. I have learned one thing after years of working with sports data: a gap in the table also knows how to speak, if we are willing to listen. When Reuters reported that the Blue Jays' home ground was being converted into a temporary golf course, my first question was not how the event looks, but which metric measures it. The answer, after I tried to list them, was: almost none. That did not make me skip the story. It made me change the question. Data is never wrong; I simply asked the wrong question. The right question here is not who wins, but what this event's design reveals about how golf is being repackaged. The technical context The event takes place inside a domed stadium, in January — a time when, without a roof, no one could play outdoor golf in Toronto. This is the most important technical detail, and also the one most easily missed when people look only at the image of a baseball stadium turned into a golf course. The dome is not the backdrop; it is the enabling condition. No roof, no event. The only person named in the article is Marnie Starkman, executive vice president of business operations for the Toronto Blue Jays. A business executive, not an athlete. In sports data analysis, when the subject named is a business executive rather than a golfer, the signal is already clear: this is a story about a venue and commerce, not about competition. I have spent many seasons tracking how stadiums are used outside the schedule. In Japan, where I live and work, a baseball stadium in winter is usually just empty space. The cost of running the dome keeps ticking, but no matching revenue stream appears. Converting it into a nine-hole golf course is a direct answer to that problem. The scoring design Four levels — par, bogey, birdie, hole-in-one — do not follow the Rules of Golf. They are a self-contained game mechanic, designed to band outcomes. A ball landing on the green is par; a miss is bogey; inside the inner pin circle is birdie; a hole-in-one is a home run. There is no iron, no wedge, no green-reading in the traditional sense. There is a tee shot from the stands and a target on the level below. When I tried to rebuild this scoring model in a spreadsheet, one thing became clear: the system cannot produce a rankable score. It measures participation, not skill. This is the core difference between an experience product and a sports contest. Every competitive event I have analyzed shares one thing: a number to compare. Here, that number does not exist, and its absence is a design statement. Throughput and the entry barrier The 90-minute figure is a commercial-throughput metric. A standard eighteen-hole round lasts four to five hours. Nine holes here take only 90 minutes — roughly one-third. At a fixed venue, that means more tee-time waves in a single day. This is the economics of an event, not of a sport. Providing clubs at each tee box is another design decision. It removes the biggest barrier for newcomers: equipment ownership. It also eliminates the equipment-compliance dimension entirely — no questions about face rebound, grooves, or ball limits. Players of all ages and skill levels are welcomed, and they need bring nothing but themselves. The vertical routing — starting at the 200 Level and finishing at the 500 Level — is a spectator-flow innovation. Participants move through the stadium rather than along a continuous fairway. This is stage design, not golf-course design. Off-course golf and the experience economy I have tracked the growth of off-course golf — driving ranges, Topgolf, indoor simulators — for years. Their common thread is detaching golf from its traditional venue. The Rogers Centre event sits in that same current, but goes a step further: it turns an entirely unrelated venue into a temporary golf course. This matters for a data reason. When golf is packaged as an experience product, it no longer depends on the number of golf courses. It depends on demand for entertainment. And entertainment demand can be served anywhere there is space, a roof, and a brand strong enough to pull an audience. Here, though, I have to criticize myself. In my first pass, I rushed to call this evidence of a growth trend. I was wrong. A single event is not a data series. And the article provides no participation figures to verify. A Vietnam–Japan lens Born in Vietnam and working in Japan, I see this event through two different training habits. In Japan, golf is tied to discipline and infrastructure — practice ranges, simulators, fixed schedules. In Vietnam, golf is expanding fast but still revolves around real courses. A golf course inside a baseball stadium belongs to neither tradition. It belongs to a third one: mass entertainment. I keep this comparison only because the gap is large enough to matter. If the event were a small game, I would not mention it. But its scale — one of Canada's most famous sports venues — makes it a data point worth recording. Operational risk The event's biggest risk lies not in sport but in operations. A golf ball flying inside an enclosed space ringed by stands requires netting and trajectory control. Foot traffic moving from the 200 Level to the 500 Level must be split into waves to avoid congestion. These are standard logistics problems for a fixed-venue event, not for a tournament. The interesting part is that the dome itself — the factor that makes the event possible — is also what mitigates weather risk. At a venue without a roof, a January rainstorm would wipe out the entire schedule. Here, the weather variable is nearly removed from the equation. In analytical language, that is a controlled variable, and controlling variables is how you reduce error. The contrarian angle Let me be clear: there is no evidence in the article that golf is becoming more accessible. The golf-for-everyone story is built on a single event, with no accompanying participation data. Correlation is not causation. A baseball stadium opening its doors to golf in January proves no trend about player growth. Moreover, this event does not transmit into the competitive-golf value chain. No ranking points, no broadcast rights, no betting market, no equipment demand. Its impact is confined to the experience and commercial layer. If anyone reads this event as a sign of systemic change, they are over-reading the data. I also note one point about the source. In the initial dataset I received, one item about a misinformation-monitoring newsletter appeared thematically disconnected from the rest. Most likely it was an extraction error. It reminded me that when data hides its face, error becomes the guide. Not every number in a dataset belongs to the story. Signals to watch What does NOT happen often tells the truth more than what does. This event produces no champion. It produces no ranking points. It produces no new market for golf equipment. It is precisely those absences that define its nature. If this model spreads, it will create a small but recurring revenue line for stadium operators — and a gateway marketing channel for the golf industry, turning non-golfers into occasional players. The signal I will watch in the next cycle is not the viral image, but the number: whether the event is repeated or franchised to another venue. If it is, the off-season stadium-monetization model is validated. If not, it was a one-off experiment. And I leave the answer open. Every number is a confession not yet written into words. Here, the number confesses that we are witnessing an entertainment format, not a contest. My job is not to confuse the two.
