PITTSBURGH (AP) — Mitch Keller allowed one run in six innings and the Pittsburgh Pirates scored five times in the seventh to rout the San Diego Padres 7-1 on Wednesday night. Keller (9-3) gave up four hits and had five strikeouts and two walks. The right-hander has surrendered one run in three of his four starts since allowing 15 across his previous three. The Pirates have won three of five after a season-worst 10-game losing streak. The five runs in the seventh all came before the first out was recorded. Josh Palacios had a pinch-hit RBI single, and Connor Joe and Henry Davis followed with two-run singles. San Diego has lost four straight and seven of nine to fall to 37-43.
