Giancarlo attended two different high schools in his teenage years. He first went to Verdugo Hills High School before switching to Notre Dame High School. After making friends at Verdugo, Giancarlo had to start all over again at Notre Dame. Switching high schools is not that uncommon among teenagers so Giancarlo did not have that hard of a time adjusting.

Giancarlo started playing baseball at a very early age and he was also active in track and field events. As Giancarlo was completing his primary education, he started playing for the Gulf League Marlins. After that beginning playing experience, he got a chance to play for the Jamestown Jammers. When he finished his time playing for the Jammers, Giancarlo started playing for the Greensboro Grasshoppers.

Giancarlo’s career baseball stats kept on improving as he got more playing time. He was able to fine tune his craft under different teams and managers. As he started to get recognized for his talent, he was offered chances to play with the better teams. He would outgrow some of his teams because his talent was just too good for them. Each new minor team he played with, he was able to walk the steps forward to eventually becoming a pro baseball player. He signed his first MLB contract with the Florida Marlins in 2010.

In his rookie season, Giancarlo impressed by hitting many home runs. In 2011, Giancarlo’s quick success came to a halt as it was reported that Giancarlo has had an eye and a leg injury. Dealing with one injury for a professional athlete is tough but having two injuries doubled the obstacle and pain for Giancarlo. The injuries impacted Giancarlo’s performance to a great degree and it took him a long time to recover. He didn’t even stop playing while he was injured but he just couldn’t perform well because of the injuries. The injures were nagging and preventing him for playing to his full potential. He didn’t want to sit out though because he loved the game so much. He wanted to be out on the field even though he was hurt. His stats fell to an average rate but he started performing better by the end of the year.

In 2012, he started playing well again as he recorded one of the fastest home runs in May of 2012. He was also named to MLB All-Star team in the same season. Getting to become an All-Star was a huge feat for a baseball player trying to regain his form after an injury. Sadly, the road to redemption for Giancarlo would end abruptly. In a game against the St. Louis, Giancarlo suffered another injury. This time, the injury would require surgery. The injury was a major loss for his team because they were relying on for a successful season. It was tragic because Giancarlo had just worked himself back into stellar play. He wasn’t even able to enjoy the fruits of his hard work because it was all taken away from him once again when he got hurt during his All-Star season.
