Span, who went 1-for-2 with a double and two walks on Wednesday, attempted his first steal of the season in the fifth inning but was caught on a perfect throw from Marlins catcher Miguel Olivo.
• Zach Duke said on Wednesday that he doesn't feel any additional pressure as the only southpaw in the bullpen.
"I hope there's some expectation there," Duke said. "I don't really see it as pressure -- I see it as opportunity."
• Johnson said the team had some trouble with the heating system in the dugout prior to Wednesday night's game, which had a first-pitch temperature of 45 degrees.
The heater was out of propane, and after it was refueled, hitting coach Rick Eckstein "almost caught on fire."
"They didn't have the heater on down there, and then we tried to turn it on, and there's no propane," Johnson said. "And then our hitting coach almost caught on fire. ... He went down there and started talking to one of the hitters that was sitting close to the fire and he was standing close to the fire. It just fried [him]. His pant leg's all burnt out."
• Catcher Kurt Suzuki said after Wednesday night's game that his hit-by-pitch in the second inning did not actually happen.
The pitch by Marlins starter Kevin Slowey was up and in, and it appeared to graze Suzuki's chest and shoulder. Suzuki took a minute to collect himself before jogging to first base.
"It didn't hit me. I already told the umpire, so you guys can say that," Suzuki said. "He asked me. I said, 'No, it didn't hit me.' It kind of scared me. ... That was a little too close for comfort though, that's for sure."
