On Tuesday, the Braves topped the Marlins, 4-3, to send Florida to its sixth consecutive loss.
Uggla did his part, finishing 1-for-6 in the victory to extend his hitting streak to 30 games. Uggla's streak is the longest active streak in the Major Leagues and one short of the Atlanta club record set by Rico Carty, when he hit in 31 straight games in 1970.
The Atlanta second baseman is hitting .345 (41-for-119) with 12 homers during the streak.
On Wednesday, the Marlins will hope to end their run with Anibal Sanchez on the mound. The Venezuelan starter is battling a streak of his own, having gone winless in his past 10 starts. He last won on June 10 against the D-backs. Sanchez and Uggla, a pair of former teammates, have matched up three times, with Uggla getting the better of the right-hander once for a homer.
The Braves will counter with Tim Hudson.
"We're hoping Anibal has run through all the bad luck that he's going to run through for the rest of the year," Marlins manager Jack McKeon said. "Maybe the worm will turn, and now, he'll be able to put six or seven wins on the board for us."
McKeon hopes Sanchez does not fall into the traps that come with such a long winless streak. Translation: He doesn't want his pitcher to try to do too much.
"You want to get out of that rut, and you try to make perfect pitches, and you're trying to be fine," McKeon said. "Just go out there and do your regular thing."
As for Hudson, he has overcome the back problems that plagued him two months ago to go 6-1 with a 2.02 ERA in his past nine starts. He limited the Marlins to one run in seven innings on July 30 and has posted a 2.79 ERA in 10 career starts in Miami.
"I've been feeling good out there, and my sinker has been working," Hudson said. "When a pitcher is feeling good, they're usually going to get the results they want. I'm having a lot of fun right now and not really thinking about it. When you get to this point of the season, you're just going out there to do whatever you can to help your team win."
Braves: McCann back on Sunday?
Brian McCann, who is on the disabled list with a strained left oblique, will have to wait until at least Friday before beginning his Minor League rehab assignment. The All-Star catcher, who has been sidelined since July 26, originally hoped to be activated Friday.
Freddie Freeman went 0-for-5 Tuesday. Still, he has reached base in 44 of his last 49 games since June 16.Marlins: Looking for clutch hits
McKeon wants his club to capitalize more on scoring opportunities and believes that is part of the reason for the recent skid. The club went 1-for-9 with runners in scoring position Tuesday and stranded six runners on base.
"I'm getting tired of looking at that three and four on the first two innings on the scoreboard," the manager said. "It's tough for us. We don't have that kind of power they have to hit that three-run homer to get us back in the game."
Gaby Sanchez entered Tuesday's game as a pinch-hitter and walked in two plate appearances. He's hitting .184 (7-for-38) over 11 games since being slowed by a tight left hamstring earlier this month.
Sanchez has only three errors in 977 total chances at first base, good for a .997 fielding percentage.
The Marlins have signed 25 of their 2011 First-Year Player Draft picks. Jose Fernandez (No. 14 overall) has yet to sign.
Florida's Mike Stanton has walked eight times over the past three games.
