Carlos Martinez was taught a valuable lesson just two weeks into spring training about using social media.

Martinez, a 22-year-old right-hander, found himself in the middle of a Twitter firestorm this week after pornographic photos and links on his "favorites" page were discovered throughout his account.

He acknowledged the situation and worked with team officials to clean up his account Monday.

"We're embarrassed, and he's embarrassed," manager Mike Matheny said. "I'm not trying to shove my morality down anybody's throat. I've made that very clear. But I also need to be concerned about it [and] realize, is this something you'd want your kids to see? Is this something that you want to be known for? Is this how you want to be remembered?

"We are, like it or not, role models. Regardless of your moral compass and where it points, those sorts of things that we're talking about are not things we want our kids seeing."
