Diamondbacks pitcher Rubby De La Rosa allowed one run on four hits in seven innings of work in Arizona's 2-1 loss to the Pirates Saturday. He was in control throughout the start, adding eight strikeouts with no walks to his totals.
De La Rosa's only blemish came in the fourth inning. He allowed a double to Neil Walker, who advanced to third on a Starling Marte ground out. Then, Pedro Alvarez doubled to right field, scoring Walker.
De La Rosa, who remains 2-1, lowered his ERA to 4.68 on the season.
