The Phillies recalled 26-year-old righthander Scott Mathieson from Triple-A Lehigh Valley this afternoon after placing lefty Antonio Bastardo on the disabled list with inflammation in his ulnar nerve.
Mathieson is something of a fan favorite, having overcome two serious elbow surgeries over the last three years and rebounding to dominate at Lehigh Valley this season.
Mathieson allowed just four earned runs in 29 innings in his first 24 appearances of the minor league season, striking out 33 and walking just 10.
His most recent outing was a rough one against Buffalo, when he allowed four runs on three hits and two walks in 0.2 innings.
Mathieson features a mid-90's fastball, but the team was hesitant about promoting him before now because they feel like he still needs to prove that he can consistently throw his slider for strikes.
But with Bastardo ailing, Mathieson was the obvious choice to be promoted.
In 2006, Mathieson was an up-and-coming starting pitching prospect in the Phillies organization. He appeared in nine games that season, eight of them starts. His highlight was an eight-inning effort against the Padres on July 5 in which he allowed three runs on six hits with five strikeouts and no walks.
But on Sept. 2, he left a start against the Braves after just one batter and proceeded to have his first Tommy John surgery. He returned to appear in seven games in 2007, but underwent another Tommy John surgery and missed all of the 2008 season.
Mathieson returned in 2009 to appear in 22 games in the minors, posting an 0.84 ERA.
He participated in big league spring training this spring, but was optioned to the minors when the Phillies felt it became clear that he was not going to make their Opening Day roster.
