PHOENIX (AP) — Pittsburgh Pirates right-hander Braxton Ashcraft pitched three scoreless innings in his major league debut. Ashcraft, one of the team’s top prospects, was recalled before Pittsburgh’s 5-0 loss at Arizona. Right-hander Isaac Mattson was optioned to Triple-A Indianapolis. The 25-year-old Ashcraft entered after Andrew Heaney was tagged for five runs and eight hits in five innings. He fanned his first batter, Tim Tawa, for his first career strikeout. He allowed two hits and walked one. He threw 50 pitches, 32 for strikes.
