Lowell's 30th home run off Astros rookie starter
(10-5) gave Florida a 3-0 lead in the first inning.
"I knew I hit it well, but you're never sure until you reach first base and look up and see it go out," Lowell said. "Things are clicking for me right now, and it seems like when I get a hit, it's a home run lately but (it's) just the way things go sometimes."
After never homering more than 24 times in a season prior to this year, Lowell became the fourth Marlin to reach 30.
had 42 homers in 1996,
hit 31 in 2000 and
had 31 in 2001.
"I'm happy because it puts me in uncharted waters and that's a good feeling," said Lowell, who is batting .386 (17-for-44) with two homers and 14 RBI in his last 12 games.
"It's great to see Mike back in the groove," Marlins manager Jack McKeon said. "It looks like he's back in top form."

"It's a great feeling to help the ballclub," he said. "Anytime you can make good contact and be productive, it's a plus. I just want to try to keep it up and do what it takes to win."
It was more than enough for Pavano (8-10), who did not yield a hit until
singled to lead off the sixth. After advancing to third on
's single, Biggio scored on
's sacrifice fly.
"It's a pleasure with this team going out and knowing you don't have to be perfect and pitch shutouts," Pavano said. "I was trying to work both sides of the plate and keep the ball down. The guys backed me up tonight and made some good plays."
The Marlins improved to 7-1 on their homestand with one game remaining and ended a four-game losing streak to the Astros. They also raised their record against lefthanded starters to 19-9 with five straight wins.
"These guys in the clubhouse believe they can win, and I feel we have a (heck) of a shot at making the playoffs," said McKeon, whose team is two games behind Philadelphia in the National League wild card race. "We're very serious about completing and wanting to win consistently and that's a very good sign."
Robertson gave up five runs and six hits in four innings for his second straight loss after a nine-game winning streak.
"I'm not one to make excuses, but I needed to adjust to the mound and got hurt early," the 26-year-old lefthander said. "I was rushing my pitches and made a few mistakes, but then I settled down and pitched well."
With its sixth loss in nine games, Houston saw its lead in the National League Central trimmed to one game over St. Louis
"We're not blind, we can see the problem areas and know what we need to do to stay consistent," Astros manager
said. "We only had one chance, and that was in the sixth inning when we scored twice and had two more on, but we got shut down after that."
