The Giants built such a streak on only one other occasion since moving to San Francisco in 1958 -- June 25-28 of 2012, a year which happened to end with a World Series conquest.
While winning 14 of their last 17 home games, the Giants have benefited immensely from their starting pitchers, who have recorded a 1.93 ERA in that span.
Heston (5-3) held up his end of the bargain in what has become familiar fashion. He recorded 12 ground-ball outs with his sinker, which also helped him strike out six.
The 27-year-old rookie acknowledged using AT&T Park's pitcher-friendly tendencies to his advantage. After all, he owns a 2.16 home ERA, compared to 5.79 on the road.
AT&T Park, said Heston, "gives you the confidence that you can throw strikes in hitters' counts and let the defense work."
For now, Heston's not worried about what fate might befall him when either Jake Peavy or Matt Cain returns from the disabled list. Heston would appear to be vulnerable to a shift in roles or even make a trip to Triple-A Sacramento, despite his overall effectiveness.
"You try not to think about how it affects you," Heston said. "Those guys are so good, you want them coming back. It's huge for the team."
