In 2004, Acosta began the season with the rookie-level Gulf Coast Braves. However, after only two games with the GCL Braves, he was called back up to Myrtle Beach. He started the next reason with the Rookie-level Danville Braves. After an impressive performance, striking out eight batters in three games, he was once again promoted to the Pelicans. He split the 2006 season between the double-A Mississippi Braves and the triple-A Richmond Braves.

Acosta pitched for Panama in the 2006 World Baseball Classic. He had an 0–1 record during the event. On October 12, 2006, the Braves purchased Acosta's contract and added him to their 40-man roster.

On August 10, 2007, Acosta was called up to the big leagues after Octavio Dotel hit the DL. He made his big league debut on August 12 pitching a scoreless inning of relief against the Philadelphia Phillies. He earned his first major league victory on September 23, against the Milwaukee Brewers. He finished the season 1–1 with a 2.28 ERA.

Acosta entered the 2008 season as a middle relief pitcher. But after Rafael Soriano and Peter Moylan were quickly placed on the DL, Acosta found himself in the closer role where he has struggled. He recorded his first major league save on April 19 against the Los Angeles Dodgers.

The Mets purchased his contract on June 3, 2011,^[1] as Michael O'Connor was sent down.

Acosta throws three pitches: a four-seam fastball, his primary pitch, at 92–96 mph; a slider (79–82); and a changeup (84–88), a pitch used almost exclusively against left-handed hitters. Acosta's delivery twists his body toward first base, giving him a release point almost directly "over the top."^[4]
