 Biographical Information
Severino was signed by scouts Ismael Cruz and Sandi Rosario for the Montreal Expos in 2004. He made his pro debut for the DSL Expos that summer. After missing the 2005 season, Severino was back in 2006, pitching for the DSL Nationals 1. He appeared in 13 games, eight of which were starts, going 2-0 with a 0.99 ERA in 45 1/3 innings, striking out 69 batters.
In 2007, he pitched for the DSL Nationals 1 again (3-0, 0.48 ERA in 3 games started) and GCL Nationals (1-0, 2.94 ERA in 13 games, five starts), going a combined 4-0 with a 2.06 ERA in 16 games (eight starts). He had 59 strikeouts in 52 1/3 innings.
He split the 2008 season between the Potomac Nationals (0-4, 3.96 ERA in 26 relief appearances) and Hagerstown Suns (4-2, 4.05 ERA in 15 relief appearances), going a combined 4-6 with a 4.00 ERA in 41 relief appearances.
He improved in 2009, as he split the season between Potomac (4-0, 2.54 ERA in 29 games) and Harrisburg Senators (6-0, 2.78 ERA in 15 games), going a combined 10-0 with a 2.62 ERA in 44 relief appearances.
He went 4-2 with a save and a 3.55 ERA in his first 40 games of 2010 for the Syracuse Chiefs. Severino was called up to the majors when Matt Capps was traded but only spent three days on the 2010 Nationals roster before being demoted in favor of Justin Maxwell; he did not appear in the majors during this span.
He finally made his major-league debut in September, 2011.
