"I'm completely and utterly embarrassed," Pillar wrote via Twitter, "and feel horrible to have put the fans, my teammates and the Blue Jays organization in this position. I have apologized to Jason Motte, but also need to apologize to the Braves organization and their fans, and most importantly, to the LGBTQ community for the lack of respect I displayed last night. This is not who I am and will use this as an opportunity to better myself."
Pillar's use of the slur on Wednesday was in response to a quick pitch from Motte, with the benches emptying after the incident.

Last season, Kang had 21 home runs and 62 RBIs in his second season with the Pirates, who signed him to a four-year, $11 million contract in 2015.
