New York Mets first baseman Pete Alonso has only been in the big leagues since 2019, but the dude has made his mark on the field. More specifically, the mark he’s made is at the plate with the bat in his hands. Simply put, Pete Alonso home runs are fun to watch and it’s almost impossible to get bored watching him launch baseballs.

Pete Alonso Home Runs So Far in His Career
From 2019 through 2024, Alonso’s 226 home runs are the second most in baseball (Aaron Judge has hit 232). That’s a lot of dingers, especially when thinking about how the 2020 campaign only consisted of a 60-game schedule because of the COVID-19 pandemic. Let’s put those homers into perspective before drooling over what he’s done since his Rookie of the Year performance.
Alonso reached the century mark in just 347 games. That’s the second-fastest anyone has gotten there in MLB history, with only Ryan Howard (325 games) getting there faster. And, while the first baseman has played in just 846 total games with New York, his prodigious power already has him ranked third on the Mets’ all-time home run leaderboard.
Now, let’s look at all the homers he’s hit since debuting with New York.
2019 Season: 53 Home Runs
It’s almost impossible to come out of the gate stronger than Alonso did as a rookie. He not only made the big-league roster as the Opening Day first baseman, but the Polar Bear immediately showed why he was ready for the bright lights in Queens.
His first 376 plate appearances – which took him to the All-Star break – resulted in a .280/.372/.634 line with 30 home runs, 68 RBI, 57 runs scored, and a 161 wRC+. This performance earned him a trip to the midsummer classic in Cleveland, along with an entry into the Home Run Derby, which he ended up winning.
Alonso’s overall production came back down to Earth in the second half, but it was still excellent. His OPS went from 1.006 to .863, while his wRC+ dropped down to 124. That was a considerable drop when looking at his first half, but it’s not as if his production fell off a cliff. He also added another 23 home runs and 52 RBI. By the end of June, Alonso broke Darryl Strawberry’s Mets rookie home run record, and by the end of August, he was the Mets’ all-time single-season home run king.
His most powerful month came in September when he slugged 11 homers on his way to breaking Judge’s MLB rookie home run record. As if this all wasn’t enough, he also joined the ranks of MLB’s Home Run Derby winners. New York’s biggest power threat didn’t just hit wall scrapers, either. Twelve of his 53 homers traveled at least 440 feet, with three being more than 460 feet. He hit them hard, too – 19 of his dingers had an exit velocity of at least 110 mph.
2020 Season: 16 Home Runs
The shortened season of 2020 was weird for lots of reasons, and it was something that certainly seemed to impact Alonso. With only 60 games to play, there wasn’t a lot of time to get in a groove and climb out of an early-season slump, which is what happened.
Through the end of August, which spanned 144 plate appearances, Alonso struggled to a .213/.333/.385 line with just six homers, 18 RBI, and 16 runs scored. He was walking at a 12.5% clip, but his strikeout rate was at 27.8%, all of which led to a slightly below-average wRC+ of 98. But as the regular season was winding down, he found his footing.
Over his final 95 trips to the plate in September, Alonso slashed .256/.316/.640 with 10 homers, 17 RBI, 15 runs scored, a 6.3% walk rate, a 22.1% strikeout rate, and a 152 wRC+. He was especially on fire in his last six games, which included four of those homers and eight of those RBI, along with a .500/.583/1.200 triple slash and a 354 wRC+.
Even when he was getting the ball over the fence, he didn’t do it with the same kind of consistent savagery that he did in 2019 – only one of his 16 taters went 450-plus feet, along with seven registering an exit velocity of at least 110 mph.
This put a little pressure on him to come back in 2021 to prove that his Rookie of the Year campaign wasn’t a fluke and that the furious hot streak he went on to finish 2020 was a sign that he was back.
2021 Season: 37 Home Runs
Alonso put together a decent first half in 2021, but it wasn’t necessarily something worth writing home about. He put up a 118 wRC+ with a .802 OPS, 17 home runs, and 49 RBI. That didn’t net him an All-Star selection, so he needed a special invite to come and defend his Home Run Derby crown, which he did…with ease.
There’s a myth out there that the Home Run Derby messes up a hitter’s swing, but Alonso was just one example of the event getting himself back on track. He slugged 20 homers with 45 RBI in the second half, which included a much higher OPS (.921) and wRC+ (147).
The first baseman launched five homers more than 440 feet in 2021, as well as seven registering an exit velocity of at least 110 mph. What’s very interesting here is how improved his plate discipline was.
While Alonso’s walk rate finished at a career-low 9.4% rate, his strikeout rate decreased for the second straight year, and the drop was much more significant this time around. After posting a 26.4% rate as a rookie, that number was 25.5% in 2020 and settled in at just 19.9% in 2021. Before Opening Day, the 27-year-old discussed his desire to control the strike zone better. He succeeded in making a noteworthy improvement.
Just as importantly, not only did he defend his Home Run Derby title, he put together one of the best single-round performances ever.
2022 Season: 40 Home Runs
It’s been another banner year for the Polar Bear. He’s played in three full seasons as a big leaguer (not counting 2020 because that was out of his control) and has three years of 30-plus homers to his name. The only Mets slugger with more during his career in Queens is Mike Piazza, who did it four times.
Of course, Alonso put himself in more exclusive company this year. So exclusive that he’s all by himself. Not only did he set the organization’s single-season RBI record, but he’s the only Mets slugger in history with multiple efforts of at least 40 homers and 120 RBI. That’s how you immediately put your stamp on franchise record books, right?
Alonso had gotten his season off to a decent start, but it was the month of May that set him on the trajectory he eventually took. Through 108 plate appearances during that section of the calendar, the first baseman slugged nine homers with a franchise-record 30 RBI and 19 runs scored. His 34 base hits were the most of any month, which helped lead to a .315/.398/.611 line and a 174 wRC+.
This was the start of two straight months with a .600 slugging percentage and a wRC+ better than 170.
2023 Season: 46 Home Runs
While Alonso’s season-long batting average dipped down to .217 in 2023, that man still got his taters. After posting 40 homers with a franchise record 131 RBI in 2022, he came back to slug 46 dingers with 118 RBI in nearly 30 fewer plate appearances. That led the Mets and was among MLB’s league leaders.
From the perspective of his home run production, Alonso was cruising by the end of May. He was the first MLB hitter to 20 homers. But then, a short stint on the injured list torpedoed his overall performance. After two straight double-digit homer months, he didn’t surpass 10 again. However, Pete didn’t hit nine in August.
Alonso has long been a crucial part of the Mets’ offense. That was on display when looking at his performance during wins and losses. When the Amazins won, Alonso slashed .277/.388/.648 with 27 homers and 83 RBI. In Mets losses, his triple slash dropped to .165/.253/.381 with 17 homers and 35 RBI.

2024 Season: 34 Home Runs
If you ask Alonso if he’s happy about his 2024 production, he’d probably say no. The first baseman’s platform year before free agency resulted in a .240/.329/.459 line with 34 home runs, 88 RBI, and 91 runs scored. But even though it might be considered a letdown for him, he still put up the power numbers we’re accustomed to seeing.
This was Alonso’s fifth campaign of 30-plus homers. He’s never finished a full season with fewer than 30 dingers, and he played in all 162 games for the first time in 2024. While the right-handed slugger didn’t enjoy a double-digit homer month, he was consistent. He hit between four and eight dingers each month, reaching eight twice (March/April and August). Alonso generally enjoyed hitting during the middle innings. That’s evidenced by his .854 OPS, a number that didn’t reach beyond .759 in either innings 1-3 or 7-9.
