The Pirates announced that they claimed right-hander Jeremy Hefner off of waivers from the Padres and claimed catcher Brian Jeroloman off of waivers from the Blue Jays. Pittsburgh has 36 players on its 40-man roster after outrighting Matt Pagnozzi to Triple-A.

Hefner, 25, started 28 games for the Padres' Triple-A affiliate in 2011, posting a 4.98 ERA with 6.9 K/9 and 3.5 BB/9 in 157 1/3 innings. He has a 3.84 ERA with 7.9 K/0 and 2.8 BB/9 in 688 2/3 career minor league innings over the course of five seasons.

Jeroloman joined the Blue Jays at the end of the 2011 season, but never entered a game. The 26-year-old, who has a career .378 OBP after six years in the minors, posted a .240/.335/.295 line at Triple-A Las Vegas this past season
