(PHOENIX) -- Oakland Athletics pitcher Bartolo Colon regrets taking testosterone, a banned substance, last year that slapped him with a 50-game suspension.

Colon appeared on Tuesday at Athletics camp and spoke about the incident for the first time.

“The only thing I can say about last year is I apologize to everybody, even the fans, the team, the front office about what happened," Colon said through a translator on Tuesday.

The Athletics rewarded the 39-year-old right-hander during the offseason with a one-year contract worth $3 million, despite him not being able to pitch in the 2012 postseason.

"I feel loved, because Oakland gave me the opportunity to come back and be part of it again," Colon continued.

Colon also said he planned on talking with each A’s player individually to express his sincere apology for letting the team down.
