MIAMI -- Facing the top of the order with a one-run lead, Tommy Hanson pitched so carefully he walked the bases loaded.
One pitch later he was back in the dugout with his shutout intact, and the Florida Marlins had squandered yet another scoring chance.
Hanson (7-4) pitched six innings Tuesday night and the Atlanta Braves won with only two hits when they sent the Marlins to their sixth consecutive loss, 1-0.
The Marlins stranded 10 and went 0 for 7 with runners in scoring position.
"I made pitches when they mattered," Hanson said. "When you get in those situations, you've got to do your best. That's all I was trying to do."
In the first five games of the Marlins' homestand, they've left 49 men on base while batting .152 with runners in scoring position.

Florida's Brad Hand (0-1) went six innings in his major league debut and allowed just one hit -- a homer by Alex Gonzalez leading off the fourth. That was enough to move Atlanta ahead of the Marlins into second place in the NL East.
"One good hit and good pitching," Braves manager Fredi Gonzalez said.
"To get two hits and win is crazy," Hanson said.
The tall right-hander allowed five walks but only two hits. He has shut out Florida in 13 innings over two starts this season.
Three relievers completed a four-hitter. Jonny Venters pitched a perfect eighth to lower his ERA to 0.49, and Craig Kimbrel followed with a hitless ninth for his 18th save in 22 chances.
The Braves have thrown eight shutouts, which ties them for the most in the majors.
Gonzalez's homer was his sixth, and first since May 8.
"I know I can hit homers," he said. "But I don't want to try every time to hit a homer, homer, homer."
Martin Prado had Atlanta's only other hit, a single in the ninth.
After Hanson walked the bases loaded in the sixth, he got Mike Stanton to ground out to end the threat.
"I was just trying to get back in the dugout with a 1-0 lead," Hanson said.
Stanton is 2 for 17 on the homestand.
The Marlins also had a scoring chance in the first, when Chris Coghlan led off with a double, but Hanson retired the next three batters. Florida's only other hits were two singles by John Buck and a single by Greg Dobbs.
Manager Edwin Rodriguez said a lineup shakeup is possible, and he might even draw names from a hat.
"We're very close to that," he said. "The energy is there, the passion is there, the desire is there. It's just not happening. Maybe they're putting pressure on themselves."
During the Marlins' losing streak, they've lost by a single run five times.
The game marked the return to Florida by second baseman Dan Uggla and Fredi Gonzalez, the Marlins' former manager. Both left Miami last year.
Uggla went 0 for 3, dropping his average to .170, worst in the majors.
Hand, promoted Monday from Double-A Jacksonville, took the turn of injured ace Josh Johnson. The rookie left-hander struck out six, and the only walk he allowed was to the game's first batter, Jordan Schafer.
"We wasted another good outing by the pitching staff," Rodriguez said. "Brad Hand was very impressive. His poise was excellent. He looks like he's been in the big leagues for a long time."
Hand pitched before a crowd of 5,126 in his most recent minor league game, and the turnout was similar for his big league debut, although announced attendance was 13,302. The Minnesota native said the crowd included at least 15 of his friends and relatives.
"I'm very happy with what I did," Hand said. "It was just one bad pitch that just cost us the game, so I'm very excited."
The Marlins hope SS Hanley Ramirez (back) will be able to resume some baseball activities by Friday, Rodriguez said. ... Coghlan went 1 for 2 with three walks and hiked his career average against Atlanta to .390.
