The Padres got their first look Saturday at two, versatile right-handed pitchers acquired in minor off-season trades. Tyson Ross allowed a home run to Jason Bay in his two innings. Wilfredo Boscan allowed a walk and hit a batter, but gave up no hits or runs in his two innings. Both struck out one hitter in the Padres 8-6 loss to the Seattle Mariners. Ross, 25, the older brother of Padres 2011 first-round draft pick Joe Ross, was acquired from Oakland in a trade that sent left-handed pitcher Andrew Werner and utility infielder Andy Parino to the A’s. Boscan, 23, was acquired from Texas in a trade for relief pitcher Cory Burns. Both have served as both starters and relievers in their careers. “I liked the way both threw,” said Padres manager Bud Black. “Tyson’s arm strength and velocity were good. He threw some good changeups which he will need to do. Boscan showed the ability to change speeds and work both sides of the plate.”
