Uggla hit a tiebreaking three-run double in the ninth, and Florida got to Street again in a 6-4 victory over the Athletics on Saturday night.
"We came back today and won," Uggla said. "I was looking for something out over the plate the same as yesterday. I was trying to get my foot down and be aggressive on it."
Cody Ross hit a tying solo homer off Alan Embree with two outs in the eighth, then Uggla lined a double to the wall in left with two outs in the ninth. Street (1-2) also blew a save opportunity Friday night and surrendered two home runs before the A's won in 11 innings.
"It's over. I can't change it. I wish I could but I can't," Street said. "I can't think about it. I can't worry about it. My stuff's been there. That last pitch was just a little up. Mislocation two days in a row. The same guy beat me twice."
Renyel Pinto (2-2) pitched a perfect eighth with two strikeouts for the victory and Kevin Gregg allowed Kurt Suzuki's RBI single and faced a bases-loaded jam before finishing for his 13th save in 17 chances. Gregg needed 34 pitches to wrap up the win, with first baseman Jorge Cantu making a great diving stop along the first-base line to save the game.
"I had a good jump and I knew I had a chance," Cantu said. "I read it good off the bat and I knew he was a pull hitter, so I leaned that way a little."
Eric Chavez and Suzuki each drove in two runs. Suzuki also had a sacrifice fly in the fourth that put the A's ahead. Chavez hit a two-run double in the bottom of the first against Ricky Nolasco after Florida made it 1-0 in the top half on an RBI single by Wes Helms.
Chavez's double was his 522nd extra-base hit, passing Reggie Jackson for second most in Oakland history behind Mark McGwire (563).
A's starter Dana Eveland pitched into the seventh despite not having his best stuff. Perhaps the biggest difference was cutting down his walks. Eveland allowed two runs on eight hits, struck out four and walked only two. He had walked 16 in his three other June starts and his 42 free passes heading into the game were third-most in the American League.
Oakland used seven pitchers Friday, so some weren't available Saturday, making Eveland's effort that much more important. Sinkerballer Brad Ziegler recorded the final two outs of the seventh working for the fourth straight game, before Embree allowed Florida's majors-leading 111th homer of the year and the 12th by Ross.
Oakland manager Bob Geren isn't about to think twice about using Street just because of his results the last two games.
"Street's our closer. That's what I do in the ninth inning of a tie game -- use my closer," Geren said. "He knows it just comes with the territory. Closer is a tough job. When you make a mistake it's very visible because it's the ninth inning. You're going to have bad games. When you have two together it magnifies it a little more."
Suzuki had another good game after driving in a career-best five runs and matching his best output with four hits Friday night -- including the game-winner in the 11th.
Bobby Crosby doubled leading off the fourth to end an 0-for-12 stretch, then singled and scored in the ninth.
"They made it exciting in the ninth, like we did in the top of the ninth," Marlins manager Fredi Gonzalez said. "It was just nice to win."
Marlins center fielder Alfredo Amezaga left in the fourth with a tight left groin that he aggravated running the bases. Robert Andino replaced him and made his first career appearance in the outfield.
