"I didn't want to offend him or nobody in Japan because I have a lot of respect, I played in Japan", said Gurriel.
Gurriel pulled at the corners of his eyes, which some interpreted as a slap at Darvish, who is of Japanese ancestry.
Shortly after the game ended, Darvish tweeted that he forgave Gurriel for the gesture and hoped people could learn from it.
As part of the punishment, Gurriel will undergo sensitivity training during the offseason while the Astros, in a gesture of support, have agreed to donate Gurriel's salary for the five games to charitable causes.
A Cuba native, Gurriel played 15 seasons in the Cuban National Series and Japan Central League from 2001-16. I've never had anything against Darvish.
Following Manfred's announcement, the Houston Astros released another apology from Gurriel, who they insist is "extremely remorseful" over the incident. I would also like to apologizs to the Dodgers organisation, the Astros, Major League Baseball and to all fans across the game, ' he said. "And acting like that, it's just disrespectful to people around the world, to the Houston organization".
"There is no place in our game for the behavior or any behavior like the behavior we witnessed last night", Manfred told a news conference before Saturday's Game Four in Houston.
"No one is flawless", Darvish wrote.
Darvish is not Chinese; he was born in Japan to a Japanese mother and Iranian father.
Some top sports columnists urged Manfred to suspend Gurriel immediately while others said he should be let off the hook. Toronto's Kevin Pillar and Oakland's Matt Joyce were each banned for two games this season after making anti-gay comments.
'There is no excuse or explanation that makes that type of behavior acceptable, ' he said. This has been a talking point amongst the media and fans, though Gurriel was still cheered by Astros fans when he was announced in the line-up on Saturday.
By imposing a penalty Gurriel and the players' union agreed not to contest, Manfred avoided a possible grievance hearing in the next few days before arbitrator Mark Irvings that would have taken attention away from the World Series. "Obviously World Series games are different than regular-season games, and I used my best judgment as to where the appropriate disciplinary level fell".
