In what many would consider Petra Kvitova's best WTA season, the big-hitting Czech won six titles in 2011, capturing her first Wimbledon title before finishing the season as the WTA Finals champion. 

But how about this: Kvitova now has five titles under her belt, is up to No.2 in the Porsche Race to Singapore, and we haven't even hit the grass at Wimbledon yet. 

After defending her title at the Nature Valley Classic to tally her tour-best fifth title of 2018, Kvitova joined the WTA Insider Podcast to reflect on her season and look ahead to her favorite Slam: Wimbledon.
