HOUSTON (AP) Rookie Brett Oberholtzer pitched a four-hitter and Jason Castro hit an RBI double in the eighth inning to lift the Houston Astros to a 2-0 win over the Seattle Mariners on Sunday.
The 24-year-old Oberholtzer struck out five and walked one. He did not allow an extra-base hit in his sixth career start and ninth appearance to lower his ERA to 2.79. He had never pitched more than seven innings entering Sunday's game.
Oberholtzer (4-1) and Seattle starter Hisashi Iwakuma matched zeros into the eighth inning.
Charlie Furbush (2-5) took over for Iwakuma in the eighth and Jose Altuve greeted him with a double that rolled into the corner of right field. Castro followed with a ground-rule double that bounced into the bullpen in right-center to give Houston the lead.
