Clayton Kershaw struck out 13 in eight innings, Justin Turner hit a go-ahead homer in the top of the ninth and the Los Angeles Dodgers beat the San Francisco Giants 3-2 on Friday night. Kershaw (9-1) outdueled Johnny Cueto to improve to 7-0 over his last eight starts, and with 82 strikeouts to just three walks during that stretch since an April 26 loss to Miami. Turner hit a 2-1 pitch from Santiago Casilla (1-2) to left field to start the ninth and the Dodgers shaved a game off the Giants' NL West lead to pull within three - though both clubs know this race surely will be decided down the stretch.
