PITTSBURGH (AP) — Stephen Kolek pitched 5 2/3 scoreless innings in his first major league start and combined with four relievers for the San Diego Padres’ eighth shutout of the season, a 4-0 victory over the Pittsburgh Pirates for their fifth straight win. Kolek was recalled from Triple-A El Paso before the game. He made 42 relief appearances for the Padres last season as a rookie after being selected from Seattle in the Rule 5 draft. Xander Bogaerts had three RBIs for the Padres, who scored all their runs in the first two innings off Andrew Heaney (2-3), who was pulled with two outs in the fourth.
