Biographical Information[edit]

Pitcher B.J. Rosenberg made his major league debut with the Philadelphia Phillies in 2012.

Rosenberg hit .368 in high school and went 18-11 with 3 saves and 213 strikeouts. As a freshman at the University of Louisville, he was only 2-5 with a 7.18 ERA, allowing 113 hits in 77 2/3 innings. In 2005, the sophomore improved to 5-4, 4.98 as the club ace, and during his junior year, he went 6-5 with a 4.72 ERA, moving into second in school history with 42 career starts. The Virginian sat out 2007 with an injury. As a redshirt senior, he was 5-5 with 9 saves and a 4.80 ERA with 62 strikeouts in 54 1/3 innings, making third-team All-Big East Conference. He finished his college career first all-time in Louisville history in starts (47), third in innings (306 2/3), sixth in strikeouts (187), tied for third in wins (18) and tied for seventh in saves.

Rosenberg was picked by the Phillies in the 13th round of the 2008 amateur draft. He was signed by scout Paul Murphy and had a strong pro debut with the Williamsport Crosscutters, going 3-1 with 10 saves and a 1.00 ERA in 21 games. He fanned 52 in 36 innings and tied for fifth in the New York-Penn League in ERA. In 2009, he got off to an excellent start with the Lakewood BlueClaws, going 7-2 with 19 saves and a 0.89 ERA in 37 games. In 50 1/3 innings, he did not give up a home run, struck out 65 and allowed just 37 hits and 10 walks. He was promoted to the AA Reading Phillies, for whom he recorded a 2.53 ERA and 3 saves in 10 outings. He was also put on Team USA's roster for the 2009 Baseball World Cup.

Rosenberg missed much of 2010 with injuries and split the season between three different clubs. He bounced back somewhat the next year with the Reading Phillies, going 5-7 with a 4.28 ERA and 2 saves in 39 games split between the rotation and the pen. He began 2012 back with Reading, and after posting a 1-0 record with a 1.12 ERA and 3 saves in his first 5 outings, he was promoted to the AAA Lehigh Valley IronPigs. He then put up a 1.74 ERA in 11 games for the IronPigs before being called up to the majors in early June. He made his big league debut with the Phillies on June 9th against the Baltimore Orioles, giving up 2 earned runs in an inning of relief work and taking the loss.
