Mooneyham, the Nationals' third-round selection Tuesday in the 2012 First-Year Player Draft, has the bloodlines of his father, Bill, a right-hander who was a first-round selection of the California Angels in 1980.
The elder Mooneyham was actually drafted four times before that, but never signed. Bill didn't make the Majors until 1986, when he appeared in 45 games for the Oakland Athletics, posting a 4-5 record in 99 2/3 innings pitched.
The younger Mooneyham also has been drafted twice before, once by the Nats in the 38th round of the 2011 Draft. A 6-foot-5, 235-pound lefty, Mooneyham was a fourth-year junior at Stanford, posting a 7-5 record and a 4.26 ERA in 2012. He struck out 90 batters while walking just 37 in 82 1/3 innings pitched.
"[Mooneyham is] a plus athlete with a fastball that touches 97 [mph] to go along with a plus curveball and changeup," Nationals director of scouting Kris Kline said, via the @Nationals PR Twitter feed. "Mooneyham projects as high as a [No. 3] starter."
