Goodbye, Polar Bear: A 60.2% Chance Mets Fans Sleep Just Fine Tonight
Pete Alonso tipped his helmet to the Camden Yards faithful on Opening Day. Then he went 0-for-3 with two strikeouts and a walk. One game later he singled off Taj Bradley in a 4-1 Orioles loss. Through two games as a Baltimore Oriole: 1-for-6, a .167 batting average, and the quiet hum of a $155 million contract beginning its five-year clock.
Meanwhile, back in Queens, the Mets were busy demolishing Paul Skenes and walking off the Pirates. Jorge Polanco — the $20-million-a-year replacement who had never played first base in his life — singled, walked in a run, and looked perfectly comfortable at a position he learned in spring training.
But two games is two games. We're not here to gloat about a sample of six at-bats. We're here because the numbers that actually matter — the ones from the last three full seasons — tell a story that should make every Mets fan exhale.
In 2023, Alonso hit .217 — a career low. In 2024, he posted a .788 OPS — also a career low. Then came 2025: a .272 average, a Silver Slugger, a career year. The perfect audition reel. The Orioles bought the audition. The question is whether they bought the trend or the outlier.
The Alonso File: Year by Year
| Year | Team | G | BA | HR | RBI | OPS |
|---|---|---|---|---|---|---|
| 2019 | NYM | 161 | .260 | 53 | 120 | .941 |
| 2020 | NYM | 57 | .231 | 16 | 35 | .827 |
| 2021 | NYM | 152 | .262 | 37 | 94 | .863 |
| 2022 | NYM | 160 | .271 | 40 | 131 | .869 |
| 2023 | NYM | 154 | .217 | 46 | 118 | .814 |
| 2024 | NYM | 162 | .240 | 34 | 88 | .788 |
| 2025 | NYM | 162 | .272 | 38 | 126 | .871 |
| 2026 | BAL | 2 | .167 | 0 | 0 | — |
Look at that table. The 2025 season — the one that earned him $31 million a year — is bookended by two of his worst. In 2023-2024 combined, Alonso hit .228 across 1,125 at-bats. That's not a slump. That's a two-year body of evidence.
"The Orioles bought the audition tape. The Mets had seen the whole movie."

We used a Bayesian Beta-Binomial model — the standard tool for projecting batting averages — trained on Alonso's last three seasons (2023–2025: 435 hits in 1,779 at-bats, a .245 average). The model asks: given what we know about recent Pete Alonso, what's the distribution of possible 2026 batting averages?
Translation: there's roughly a 6-in-10 chance Alonso finishes 2026 below .250. And only about a 1-in-10 chance he matches the .270+ batting average that justified his contract. The model isn't cruel — it's just honest about what 1,779 recent at-bats suggest.
The Decline Curve
Rolling three-year batting averages don't lie. They smooth out the noise and reveal the trend beneath.
The peak was 2020-2022 at .262. Since then, the curve drops below .250 and stays there. The 2025 bounce-back wasn't strong enough to reverse the slide — it only slowed it. The projected 2026 median? Right back at .243.
2026 Projected BA by Percentile
| Percentile | Projected BA | What It Means |
|---|---|---|
| 10th | .218 | Disaster. Worse than 2023. |
| 25th | .230 | Below the Mendoza+ line. Tough to justify $31M. |
| 50th (median) | .243 | Most likely outcome. A below-average regular. |
| 75th | .257 | Decent. Roughly his career average. |
| 90th | .272 | Best case. Repeats 2025. Only 10% likely. |
The Money: What the Mets Saved
Pete Alonso signed for 5 years, $155 million ($31M/year) with Baltimore. The Mets replaced him with Jorge Polanco on a 2 years, $40 million ($20M/year) deal. That's $11 million per year the Mets didn't spend — money that helped them land Marcus Semien, Luis Robert Jr., and Devin Williams.
The Mets bet that Alonso's best years were behind him. The model says they have a 6-in-10 chance of being right. And if Polanco gives them even 80% of Alonso's production at 65% of the cost, the math wins.
They've Seen This Movie Before
The greatest hitter of his generation left St. Louis for a 10-year, $240 million deal in Anaheim. He hit .217 in April 2012 — sound familiar? — and never posted a season above .285 again. With the Cardinals: .328/.420/.617 over 11 years. With the Angels: .256/.311/.448 over 10. The Cardinals won the 2011 World Series on his way out the door, then kept winning without him.
The Orioles — yes, the same Orioles now paying Alonso — signed Davis to a 7-year, $161 million contract after he hit 47 home runs in 2015. By 2018, Davis posted a .168 average — the lowest in MLB history for a qualified hitter. He retired in 2021. Baltimore is still paying him through 2037. They did not learn.
The pattern is brutally consistent. Power-first first basemen who sign megadeals in their late twenties tend to decline faster than anyone expects. Alonso turned 31 in December. The Orioles are betting against a very stubborn actuarial table.
Meanwhile, in Queens
The Mets won 11-7 on Opening Day, chasing Paul Skenes after two outs. They walked off the Pirates 4-2 in 11 innings on Day 2 with a Luis Robert Jr. three-run bomb. Polanco singled, walked in a run, and played first base like he'd been doing it for years. Bo Bichette looked sharp at short. Marcus Semien settled into second.
The 2026 Mets didn't just replace Alonso — they redistributed his salary across three positions and arguably got better. That's the real stat.
"The best time to sell a stock is when someone else is willing to pay more than it's worth. The Orioles just paid full price for a three-year downtrend."
