Pete Alonso hits 300th career home run against Mets as Orioles win in extra innings

Pete Alonso hit his 300th career home run in the ninth inning against his former team, tying the game and sparking a Baltimore extra-inning victory over the Mets, per CBS Sports' Dayn Perry. The milestone arrived at Citi Field — the ballpark where Alonso spent the earlier portion of his career — and it kept the Orioles alive in the AL wild-card race.

What happened

Per CBS Sports, Alonso's 300th career home run came in the ninth inning and knotted the score against New York. Baltimore went on to win in extra innings. The victory, per the report, keeps the Orioles in the AL wild-card hunt.

The timing and the venue gave the moment a particular texture. A day earlier, per a previous Posterior Wire item, Alonso had returned to Citi Field as a member of the Orioles and received cheers from the crowd while chasing that 300th home run milestone. He needed one more swing.

Why it matters

A ninth-inning, game-tying home run against the franchise that employed you for years is the kind of thing that writes its own ceremony. But operationally, what matters to Baltimore is the two points in the standings. The Orioles entered this stretch of the schedule needing every win they could find, and an extra-inning result against a National League opponent — one that required a dramatic late comeback to even reach extras — is the sort of game that can define a September push or a September obituary, depending on how the rest of the schedule cooperates.

Alonso's role in that equation is worth noting. He arrived in Baltimore as a recognizable offensive presence, and a 300th career home run is a marker that speaks to sustained production over a long stretch of major-league time. The milestone itself is not a transaction or a roster move — it is simply a number that lands in the record, and this one landed in the ninth inning of a game Baltimore needed.

Where the club stands

Baltimore is 74-78 (.487) and fifth in the AL East, with the division race already settled against them — they are eliminated from that chase, 18 games back. The wild-card path is the only road still open, and at 3.0 relative to the cut line, ranking sixth in the AL wild-card standings, the margin for error is thin enough that extra-inning wins feel less like bonuses and more like requirements. The Orioles are riding a two-game winning streak.

That 3.0 gap is not a comfortable number in mid-September, but it is not a closed door either — which is precisely why a game like Tuesday's, won in extra innings after Alonso tied it in the ninth, carries weight beyond the box score.

The roster around that wild-card chase has absorbed some turbulence in recent days. Kyle Bradish was placed on the 15-day IL with lower abdominal discomfort, removing him from the rotation — a development reported earlier this week. Luis Robert Jr., who joined the Orioles and then suffered a left hamstring injury, is on the IL with his return this season described as uncertain, per a prior Posterior Wire item. Adley Rutschman received a cortisone shot and was given a planned day off, per an earlier report, indicating an underlying injury concern.

The depth of the roster has been tested throughout this stretch. Albert Suarez re-signed with Baltimore on a minor-league deal — for the fifth time this season, per a Posterior Wire item from earlier this week — after being designated for assignment. Under standard league mechanics, a minor-league deal does not add a player to the 40-man roster, and a player designated for assignment must be traded, released, or placed on waivers within seven days. The September expansion to 28 players, a standard league mechanic that applies to all clubs from September 1 through the end of the regular season, gives Baltimore more flexibility to manage these moving parts than it would have had in August.

What we don't know yet

Per CBS Sports, the report establishes that Baltimore won in extra innings and that Alonso's home run tied the game in the ninth. The precise final score, the inning in which Baltimore took the lead for good, and the full game details are not specified in the report.

On the injury front, the statuses of Rutschman and Robert remain uncertain beyond what has been previously reported. Rutschman's cortisone shot and planned day off were noted earlier, but the extent of the underlying concern has not been detailed. Robert's return this season was described as uncertain in a prior Posterior Wire item, and nothing in the current report updates that picture.

Shane Baz, who exited a game against the Mets after taking a comebacker off his elbow and hoped to avoid the IL — per a Posterior Wire item from earlier this week — also has an unresolved status that bears watching as Baltimore tries to piece together a functional pitching staff for the final stretch.

What to watch

Wednesday's game at Citi Field has Chris Bassitt listed as the probable starter for Baltimore against Robert Stock for New York. That is the immediate next step for a club that just won in extra innings and needs to keep the streak going.

After the Mets series concludes, Baltimore returns home to face the Milwaukee Brewers on Friday and Saturday at Oriole Park at Camden Yards. Those games will come against a National League opponent with no direct bearing on the AL wild-card standings, but wins are wins in September when you are 3.0 outside the cut line.

The Bradish situation is worth monitoring as well. His placement on the 15-day IL with lower abdominal discomfort removes a rotation piece at a moment when Baltimore can least afford to be short-handed on the mound. How the club fills that gap — and whether any of the injured players move closer to a return — will shape what the Orioles actually look like when the schedule reaches its final pages.

For now, the ledger shows a win, a two-game streak, and a 300th career home run delivered in the ninth inning by a man who used to call the opposing ballpark home. The Orioles will take it.
