The Giants have rediscovered the long ball on this latest road trip. On the season, they’re averaging .60 homeruns a game, good for the 30th in the MLB. As it turns out, 30th is dead last. Who knew?

Anyway, the dearth of homeruns should be cause for concern. Homeruns are the most efficient means of scoring runs. The teams that hit homeruns tend to do well. The teams that don’t, do poorly. Last season, the two worst homerun hitting teams were the Houston Astros and the San Diego Padres. Of course, both had forgettable seasons.

The last four World Series winners certainly knew their way around the bases.

2011 Cardinals 1.00 0.96
2010 Giants 0.99 1.34
2009 Yankees 1.49 1.31
2008 Phillies 1.32 1.28

In 2002, when the Giants squared off against the small ball of the Los Angeles Angels of Anaheim, it was homeruns that made the difference.

In short, home runs are important. The A’s and Giants current streaks are further evidence of this.

Unfortunately, Matt Cain and Brandon Crawford are not reliable homerun hitters. Neither is Melky Cabrera and his career .309 SLG%.

So, do enjoy this recent surge, but also know it is temporary.

Speaking of homeruns, Matt Cain has given up seven in his last four starts. Today marked the fifth time this season he allowed two or more homeruns in a game. Last season, he never allowed a multi-homerun game. Draw your own conclusions.
