## Alonso reaches 300 homers in surreal scene

## Mets fans cheer for the opposing player
After Alonso rounded the bases, Mets fans at Citi Field broke into cheers of his name. He took a curtain call from the home crowd despite playing for Baltimore.

> "Everyone in the dugout was saying, 'Go out there,' and they were right."
## Senga unbothered by the crowd reaction
Mets pitcher Kodai Senga said the crowd's support for Alonso did not bother him because of their history together. He said he would have been irked if any other hitter had received that reaction.

> "I've never seen anything like that before."
## Manaea disagrees with the crowd's reaction
Sean Manaea, a close friend of Alonso, said the Mets team works hard every day and the crowd's reaction to an opposing player was disrespectful. He threw five and one-third effective innings.

> "I love him to death, but as a team... that kind of reaction to an opposing player is crazy to me."
## Fans turn on Mets management
After Alonso's curtain call, the crowd shifted to chanting "Fire Stearns," directing anger at the person responsible for trading away the star player. The Mets are having a disappointing season.
## Mayo seals it with inside-the-park homer
Coby Mayo hit an inside-the-park home run in the 11th inning off Jonathan Pintaro, with A.J. Ewing crashing into the wall trying to catch it. The three-run blast put the Orioles up 7-5.
## Orioles stay alive in wild-card race
The Orioles' 7-5 victory keeps them fighting for a wild-card spot as the season winds down. The win came against a Mets team struggling in September.
## Alonso's legacy with the Mets lives on
Alonso spent years with the Mets and built a strong connection with fans. His departure to Baltimore has left a void the team struggles to fill this season.
