Michael Morse’s eyes grew wide as a bleacher bum’s with a home run ball screaming his way. “Really?” said Morse, informed that the Giants hit the fewest homers in the majors in 2012, when they won the World Series. “If that’s true, I guess we need to slow the pace down.” The Giants’ new left fielder does sarcasm as well as he hits souvenirs. That’s a comforting thought. The entirety of their 7-2 win at Dodger Stadium was a comforting thought, really. This wasn’t a victory built on a big inning that included a sun ball, a bloop and a two-out sand wedge single from the pitcher, like the first inning Friday. This was three no-doubt homers, lots of traffic on the basepaths and some patience to go along with the power, too. The Giants drew six walks and worked tough at-bats throughout the afternoon. The nine home runs in six games are what catch your attention. The Giants needed 16 games to hit that many last season. And maybe they can’t count on so much trotting when they return home to AT&T Park, where there’s a snap in the air and a 25-foot brick wall.
