Giants unhappy with sloppy loss

San Francisco still seeking forward momentum before opener

SAN FRANCISCO -- Thursday's meaningless exhibition game against a split squad of Seattle Mariners left the Giants with a regular-season case of the blues.

Not only did the Giants' 7-2 defeat drop their Major League-worst spring record to 8-21-2, the way they lost bothered them more than an exhibition setback should. The Giants trailed 6-0 after four innings, collected only five hits, heard AT&T Park fans cheer sardonically after they scored their first run, committed two errors and made another mistake that didn't appear in the box score. Seattle's Yuniesky Betancourt, who drove in five runs, scored another in the sixth inning during a brief lull in play when first baseman Rich Aurilia held the ball.

The clubhouse was eerily silent after the game, as if the team were in the throes of a long regular-season losing streak.

"Making some mental mistakes throws you more than anything," manager Bruce Bochy said. "We'd like to create some momentum before Opening Day, and certainly the way it went tonight is not going to do it."

Said right-hander Matt Cain, who said he felt good despite allowing six runs (five earned) in four innings, "Obviously, we have to get momentum. We can't all of a sudden turn it on. It's something we all have to do."
