Carlos Agustín Mármol (born October 14, 1982) is a Dominican former professional baseball relief pitcher.

He played in Major League Baseball (MLB) for the Chicago Cubs, Los Angeles Dodgers, and the Miami Marlins.

[1] Mármol made his Major League debut on June 4, 2006, against the St. Louis Cardinals in a relief appearance.

After Cubs pitcher Kerry Wood was placed on the disabled list for the second time of the season, Mármol was called on to make a spot start.

On June 11, against the Cincinnati Reds, in his first Major League start he allowed just one run on two hits while striking out seven, to earn the win.

Due to an injury to closer Ryan Dempster, Mármol was called upon to pitch in the ninth inning of a game against the Colorado Rockies on June 27, 2007.

With Wood suffering from a blister, Mármol was selected to replace him at the All-Star Game, and pitched a scoreless 13th inning of relief in an eventual 15-inning National League loss.

[9] The Dodgers promptly outrighted him to the minor leagues, where he made 3 appearances for Class A Rancho Cucamonga and 2 for AA Chattanooga.

On February 6, 2014, Marmol agreed to a one-year contract with the Miami Marlins worth $1.25 million.

[15][16] On February 16, 2016, Mármol signed a minor league contract with the Boston Red Sox, with an invitation to spring training.
