SAN FRANCISCO (AP) — It's been quite some time since Giants manager Bruce Bochy heard booing from the home crowd at AT&T Park. With his club struggling to pull itself out of a deepening funk at the waterfront stadium, the sounds of discontent are growing louder with each game. The Giants have dropped all five games on this current six-game homestand and have lost six consecutive games overall. The Giants have scored five runs over the past five games, with just four extra-base hits. Liriano struck out a season-high 11 in seven innings to win consecutive starts for the first time this season while Josh Harrison and Travis Snider both hit home runs for the Pirates, who moved within one game of first-place Milwaukee in the NL Central. A former minor league prospect for the Giants, Liriano (3-7) gave up a home run to Mike Morse but was otherwise stellar while leading the surging Pirates to their eighth win in 11 games. Harrison hit a 3-2 pitch from Giants starter Tim Hudson off the facing of the brick wall in right field for his first career leadoff home run.
