"Trent is an athletic, extremely projectable right-handed starting pitching prospect with a soild frame, sound delivery mechanics and clean arm action with a present and future quality pitch arsenal," said Pirates Senior Vice President and General Manager Neal Huntington.
Pittsburgh also signed left-handed pitcher Zac Fuesser, the club's 34th round selection in the 2009 Draft.
Fuesser went 5-2 with four saves and a 4.35 ERA in 19 games (four starts) as a freshman this year at Walters State Community College in Morristown, Tennessee. Zac also struck out 60 batters in his 49.2 innings of work while limiting opposing hitters to a .222 batting average. During his senior year in high school, Fuesser was named the South Carolina Gatorade Player-of-the-Year, a third-team Rawlings All-American, All-State and All-Region at York (South Carolina) Comprehensive High School in 2008.
"Zac is a quality framed, athletic left-handed pitcher with a feel for pitching, a solid pitch mix and the traits of major league starting pitchers," said Huntington.
The Pirates have signed 17 of their 51 selections from this year's draft.
"We are very pleased to get both Stevenson and Fuesser signed and out pitching this summer as we firmly believe the experience will expedite their development," said Huntington.
