SAN FRANCISCO -- Pittsburgh Pirates closer Tony Watson didnt think twice when catcher Francisco Cervelli signaled for an intentional walk that would have loaded the bases in the ninth inning.It was a miscommunication that almost turned into a costly mistake for manager Clint Hurdles ballclub until pitching coach Ray Serage came charging out of the visitors dugout to clarify things.Watson threw ball one to Ehire Adrianza before getting corrected, then retired the final two batters on seven pitches to preserve Pittsburghs 4-3 victory over the San Francisco Giants on Tuesday night.I saw Cervy put the fingers up and threw the first one, then all of a sudden I saw papers flying out of the corner of my eye in the dugout, Watson said. I stepped off and knew something was up. Ray came out ... and wanted to go right at him.Watsons sixth save of the season helped the Pirates to their fifth win in six games and helped keep them one game behind the second NL wild card. It also knocked the Giants out of first place in the NL West.San Francisco had runners on second and third with one out in the ninth following an error by Pirates shortstop Jordy Mercer and Joe Paniks double.Cervelli then called for an intentional walk to Adrianza and Watson complied by throwing a pitch well out of the strike zone. After Serage came out to stop the intentional walk, Watson got Adrianza to pop up to the infield before Angel Pagan grounded to second to end the game.(Cervelli) saw an infield defense that has a similar sign as an intentional walk, Hurdle explained. You cant get anybodys attention because the crowds so loud so were yelling and screaming at the top of our lungs and nobodys looking at us. Ray sprinted out ... and he was going to tackle somebody to stop the play.Jung Ho Kang hit a tiebreaking home run in the eighth inning, Andrew McCutchen had two hits while Gregory Polanco drove in two runs without a hit for Pittsburgh.Kang homered off reliever Derek Law (4-2) one pitch after McCutchen was thrown out attempting to steal second base. It was Kangs 14th home run this season and third in four games.A 1-2 count is tough but I tried to stay on it and I tried to expand the zone, Kang said.Antonio Bastardo (1-0) retired three batters for his first win since Aug. 7, 2015.
