Many offensive tweets that included racist and homophobic thoughts from Hader surfaced during the game.
Hader was asked about the tweets after the game, and said he was "young, immature, and stupid".
"It was something that happened when I was 17 years old, and as a child, I was immature", Hader said. I obviously said some things that weren't excusable. He said he plans to apologize to his teammates, saying they don't reflect on him as a person now. "I said some things that are inexcusable".
"When anybody does something like that, you're always surprised", said Cain, USA Today reported. "At the end of the day, you've got to give people a second chance, you understand you have to forgive people, move on from it".
Hader also reportedly tweeted a series of sexist and mysognnist tweets that were screenshotted prior to his account being switched to private.
Ten new moons-including one 'oddball'-discovered around Jupiter
The lost moons were initially sighted in 2003, but scientists could not define their exact orbits and lost track of them. Sheppard said the oddball moon is "likely Jupiter's smallest known moon, being less than 1 kilometer in diameter".
Deputy Commissioner Dan Halem, speaking outside the National League clubhouse, said he had spoken to Hader. "There is no excuse for what is said".
Hader said he was in high school at the time and still learning who he was. "I really don't know exactly what all's out there". You live and you learn.
Some of Hader's family removed his replica jersey while at the All-Star Game, according to Jeff Passan of Yahoo Sports.
"I'm ready for any consequences that happen for what happened seven years ago", he said.
"I'm sure there were some lyrics, rap lyrics, being tweeted", Hader told reporters. But Major League Baseball is not happy tonight, I can assure you, that an ugly social media incident blew up during its biggest showcase of the regular season.
Then, as the former Orioles draft pick and current Milwaukee Brewers relief pitcher exited the game and returned to the clubhouse, he realized the three-run home run he allowed to Jean Segura would be the least of his problems.
