Badenhop, 30, went 2-3 with a 3.47 ERA (24 ER/62.1 IP) in 63 relief appearances for Milwaukee in 2013. He held right-handed batters to a .229 (35-for-153) average, and finished the season with a 2.05 ERA (5 ER/22.0 IP) over his last 21 games of the season, allowing earned runs just twice in that span. He issued just 12 free passes this season and ranked seventh among qualifying National League relievers in fewest walks per nine innings pitched (1.7).
Over the last two years, his first two full seasons in the majors, Badenhop has posted a 3.25 ERA (45 ER/124.2 IP). He and San Francisco's Sergio Romo are the only pitchers to appear in at least 60 games while allowing fewer than 1.0 home run per nine innings and 2.0 walks per nine innings in both 2012 and 2013. His 1.7 walk rate in that time ranks fifth among major league relievers with at least 115.0 innings. Since the start of 2012, opponents have grounded into 16 double plays with Badenhop on the mound, a tally surpassed by only nine other major league relievers.
For his career, right-handed batters have hit .254 (218-for-858) against him, but just .234 (74-for-316) over the last two seasons. Badenhop has posted a 2.59 ERA (12 ER/41.2 IP) in 43 career appearances against American League East division opponents, which includes four career games at Fenway Park where he has a 2.45 ERA (2 ER/7.1 IP).
In parts of six big league seasons, Badenhop has a record of 18-20 with three saves, and a 3.98 ERA (166 ER/375.1 IP) in 280 games (10 starts) between the Miami Marlins (2008-11), Tampa Bay Rays (2012), and Brewers (2013). Originally a 19th round selection of the Detroit Tigers in the 2005 June Draft, Badenhop was a part of the Tigers and Marlins trade for Miguel Cabrera which also included current Red Sox left hander Andrew Miller.
Ortega, a 20-year-old left-handed pitcher, spent last season with the Rookie-level Gulf Coast League Red Sox where he went 3-3 with a 2.45 ERA (10 ER/36.2 IP) in 12 games (one start). Signed by Boston as an international free agent on July 2, 2011, Ortega has gone 9-6 with a 2.25 ERA (24 ER/96.0 IP) with 55 strikeouts in 25 games (14 starts) over his two-year professional career.
With the acquisition of Badenhop, the Red Sox 40-man roster is now at 40.
