J.C. Ramirez signed with the Seattle Mariners in 2005 after being scouted by Luis Molina and Nemesio Porras. He began his minor league career in 2006, pitching for the VSL Mariners. With them, he went 5-1 with a 1.66 ERA in 14 games (13 starts). He led the Venezuelan Summer League in ERA.
He pitched for the Everett Aqua Sox in 2007, posting a 3-7 record and an ERA of 4.30 in 15 games started. He was one loss shy of leading the Northwest League. In 2008, he pitched for the Wisconsin Timber Rattlers, going 6-9 with a 4.14 ERA in 25 games (22 starts). Baseball America rated him the #17 prospect in the Midwest League.
With the High Desert Mavericks in 2009, he went 8-10 with a 5.12 ERA in 28 games (27 starts). On December 16, 2009, he was traded to the Philadelphia Phillies with Phillippe Aumont and Tyson Gillies for Cliff Lee. He split the 2010 season between the Clearwater Threshers and Reading Phillies, going a combined 7-7 with a 4.82 ERA in 24 starts. With Reading for all of 2011, he was 11-13 with a 4.50 ERA. He tied Stephen Fife and Austin Adams for second in the Eastern League in wins (one behind Austin Hyatt) but also led in losses. He led Phillies farmhand in losses (one ahead of Tyson Brummett) while being 4th in wins. Moving to relief, he split 2012 between Reading (0-2, 3 Sv, 3.62) and the Lehigh Valley IronPigs (3-2, Sv, 4.28). His 45 games pitched were 7th in the Philadelphia farm system.
Ramirez pitched for Nicaragua in the 2013 World Baseball Classic Qualifiers, appearing in their 6-2 loss to Panama. He relieved Pedro Rayo in the 7th with a 4-2 deficit. Carlos Lee grounded out, Luis Castillo drew a walk, Jose Macias grounded Castillo over and Angel Chavez drew an intentional walk. Concepcion Rodriguez singled in a run and Jeffer Patino walked as well. Jhonny Polanco then relieved Ramirez. He began the summer of 2013 back with Reading but moved up after 4 games (1-0, 2 H, 8 K in 7 IP, 0 R) and was 2-2 with two saves and a 6.53 ERA after 23 games for Lehigh Valley. He was called up when Mike Adams went on the DL.
In his major league debut for the Phillies against the New York Mets on June 23, 2013, he struck out the side in order in the 8th inning of an 8-0 loss; his victims were Juan Lagares, Omar Quintanilla and Kirk Nieuwenhuis. He relieved Joe Savery and was replaced by Jake Diekman in the 9th.
His date of birth is in dispute, some sources say 1986 while others say 1988; mlb.com and Baseball-reference both list 1988.
