Hernandez shut down the Giants in his last start, allowing one run on six hits over seven innings. But prior to that June 17 game, the 26-year-old posted three consecutive starts shorter than seven innings. He allowed 14 earned runs over 17 innings in those games, going 0-2.
Seattle pitching coach Carl Willis suggested a minor adjustment prior to Hernandez's recent start against San Francisco. Willis noticed Hernandez shifting slightly to his right when starting his delivery.
"I was trying to be straight to home plate and I think it worked pretty good, because I was commanding my fastball and that was the key," Hernandez said. "Because when I command the fastball, my breaking ball is better. It's not new mechanics, just facing straight to home plate instead of starting sideways."
Marquis, meanwhile, is in the middle of what manager Bud Black described as "sort of a second lease on life." The 13-year veteran was designated for assignment by Minnesota late last month after going 2-4 with an 8.47 ERA in seven starts.
The right-hander is just 1-2 in three starts with San Diego, but boasts a gleaming 1.86 ERA. His lone win also came against Seattle. Marquis threw 6 1/3 shutout innings against the Mariners while allowing six hits on June 13.
"The guy, you look at his track record, there is some well-pitched baseball," Black said. "[Padres general manager Josh Byrnes] went and got him when there was a need for us, and he has taken a hold of this opportunity. He's pitching well. Let's hope it continues."
Mariners: Montero gets another off-day
Catcher Jesus Montero didn't start on Friday. It was the rookie's third off-day in a row, his longest such stint of the season.
"I wanted to do that," manager Eric Wedge said. "I think it's a good time for him to have a couple days where mentally and physically he can get away from it a little bit. And we'll get him back in there [Saturday]."
After Friday's game, the Mariners are hitting .336 (38-for-113) with seven doubles, 5 homers, and 23 runs scored through four games of their current road trip.
Padres: Forsythe returns to lineup
Infielder Logan Forsythe went 2-for-4 with a double and two runs on Friday in his first start since June 12, after dealing with abdominal discomfort. He appeared in three other games in-between, but only as a pinch-runner or pinch-hitter.
Forsythe also missed the season's first 54 games after undergoing foot surgery in March.
"It's baseball, and you're always going to have tweaks like that," Forsythe said. "Hopefully, I'll be able to space them out a little more."
Cory Spangenberg, the Padres' first-round Draft pick in 2011, was placed on the seven-day disabled list Friday because of concussion-like symptoms. He was struck on the left side of his helmet by a ball during pregame drills. The infielder was hitting .291 with 21 stolen bases in 66 games for Class A Lake Elsinore.
Despite being 25-46 overall, the Padres own a 7-6 record against the American League this year.
San Diego's three-game sweep of Seattle last week remains its only sweep of the season.
