"It's been fun here so far, the way the fans have been," said the right-hander, acquired from the Marlins for Carlos Zambrano. "Opening weekend was awesome here, and something I've never seen before. I'm ready to get going now and get that first game, and get the season started."
It's different because the Marlins, where Volstad pitched before, didn't have 40,000 fans every day.
"The energy level, excitement -- and it's not a secret what was going on as far as attendance in Florida," Volstad said. "There's definitely a difference."
So far, Wrigley Field has been two different ballparks, depending on the wind. Volstad will peek at the flags on top of the scoreboard on Monday.
"The first day, it was howling in and about 40 degrees, and [Saturday] was nicer," he said. "It's something you've got to get used to. For me, a sinkerballer, trying to keep it down, the way the conditions are doesn't really matter."
