Richmond has only thrown one pitch in the Major Leagues since 2009, when he made 24 starts for the Blue Jays after making the club out of Spring Training.
During his absence, he battled a lingering right shoulder injury and an inconsistent 2011 campaign. But following a series of setbacks to Toronto's pitching staff, Richmond is back with the Blue Jays and is expected to serve in a long relief role.
"I just stayed really positive, regardless of being told 'No' your whole life -- 'You don't throw hard enough, you're too old,' things like that," Richmond said. "Just stay positive and focus on what you can control.
"It has been a tough road. I was taken off the 40-man last year, had a tough year coming off an injury my first full season, this year bounced back, put a bunch of quality starts together. I was able to show them I can keep my team in the game and pitch in a tough league."
Richmond was recently inducted into the Canadian Baseball Hall of Fame along with the 2011 Canadian National Team, which won gold at the Pan-Am Games. Richmond recorded the final six outs in a 2-1 victory over the United States to capture the first gold medal for Canada's senior national team at any event.
The 32-year-old Richmond is 9-14 with a 5.26 ERA in 33 career games in the Majors, all of which were with the Blue Jays.
