He attended high school at Liceo Sol Ana Nolan in San Pedro de Macoris, Dominican Republic, where he was born.
Ciriaco was signed by the Arizona Diamondbacks as an amateur free agent in 2003.
In 2005, Ciriaco played for the Diamondbacks' advanced rookie team, the Missoula Osprey. He then played for the team's A affiliate, the South Bend Silver Hawks in 2006. He spent the next two seasons with the Advance A class Visalia Oaks, gaining a promotion to Double-A Mobile Bay Bears in 2009. Ciriaco then began 2010 with Triple-A Reno Aces. At the beginning of the season, Baseball America ranked Ciriaco 27th among D'Backs prospects heading into the season, praising his defense and speed.
On July 30, 2010, Ciriaco and Chris Snyder were traded to the Pittsburgh Pirates in exchange for D. J. Carrasco, Ryan Church and Bobby Crosby. He was assigned to the Pirates' AAA club, the Indianapolis Indians. Ciriaco was a late season call-up for the Pirates and made his major league debut on September 8, 2010. He hit an RBI double in his first Major League at-bat, off Cristhian Martínez of the Atlanta Braves. He would play in eight games for Pittsburgh that season.
During the team's 2011 spring training, Ciriaco posted a .333 batting average while playing in a team-high 26 games. On March 27, 2011, he returned to Indianapolis after the Pirates named Rule 5 selection Josh Rodriguez to the team's Opening Day roster. The announcement came moments after Ciriaco and Rodriguez helped the Pirates defeat the Tampa Bay Rays by scoring on a throwing error in the bottom of the ninth inning to give the team a 5–4 victory.
Boston Red Sox
On January 3, 2012, the Boston Red Sox signed Ciriaco to a minor league contract. He attended spring training as a non-roster invitee, and led the Red Sox in batting average (.412), runs (14), hits (18), stolen bases (8), and games played (26), while collecting a .444 on-base percentage and a slugging of .651. He then was assigned to Triple-A Pawtucket. The Red Sox purchased his contract on July 6.
In 64 games with the Pawtucket Red Sox, Ciriaco hit for a .301 average, including four home runs and 21 RBIs.
The next day, Ciriaco made his Red Sox debut in the first game of a day-night doubleheader against the New York Yankees, getting the start at second. In the second game of the doubleheader, broadcasters Joe Buck and Tim McCarver named him the Player of the Game and praised Ciriaco for having a great glove at shortstop while providing some timely hits and speed on the basepaths. Ciriaco finished the game with four hits and 4 RBIs.
Also seeing time at second base and third, the three outfield positions and designated hitter, Ciriaco batted .293 with 16 stolen bases in 76 games for the Boston Red Sox in 2012. On June 10, 2013, Ciriaco was designated for assignment to make room for Will Middlebrooks.
San Diego Padres
On June 14, 2013, Ciriaco was traded from the Boston Red Sox to the San Diego Padres for a player to be named later. He hit .238/.284/.333 with 6 SB and 4 RBI in 23 games with the Padres before being designated for assignment on July 12.
