A striker born in Peru, Carlos Alberto Orejuela Pita began his professional playing experience at the youth level at Universitario de Deportes. He moved into the first team squad in 2000, and over the next two seasons, slowly made his way into the starting lineup. Scoring twice in 23 appearances, Orejuela decided to move to Sport Boys in search of regular action.
Orejuela really took off at Sport Boys, scoring 14 goals in 30 appearances, grabbing the attention of Cienciano who picked him up in 2004. An injury struck season saw Orejuela play just 20 games and score twice before he moved to Sporting Cristal for 2005. A season, 26 games and two goals later, Orejuela was moving again, this time to Alianza Lima where he scored three times in 23 games.
Back at Sporting Cristal in 2007, Orejuela starting all the 36 league games, only picking up 7 goals through the season before moving on to Universidad Cesar Vallejo. At his new club, Orejuela had the time of his life, scoring 11 times in just 20 appearances, booking a return back to his original club, Universitario de Deportes.
However the run of form wouldn’t continue as Orejuela scored just 5 times in 24 games for the club. He moved to Total Chalaco in 2009, hoping to get some regular action but with just 13 appearances under his belt, Orejuela managed to score just 4 goals.
