Mitch Keller struck out 10, matching his career high, in six innings for the Pittsburgh Pirates in a 6-2 victory over the Los Angeles Dodgers on Thursday to win the three-game series. Keller (3-0) gave up two runs on five hits, getting out of a third-inning jam with runners on first and third and one out by striking out James Outman and forcing David Peralta to ground out. The right-hander also had 10 strikeouts in six innings last Aug. 30 in a 4-2 victory over the Milwaukee Brewers.
