Task: Question Answering
Input (English): Passage: After finishing last in the NL Central with 66 wins in 2006, the Cubs re-tooled and went from "worst to first" in 2007. In the offseason they signed Alfonso Soriano to a contract at 8 years for $136 million, and replaced manager Dusty Baker with fiery veteran manager Lou Piniella. After a rough start, which included a brawl between Michael Barrett and Carlos Zambrano, the Cubs overcame the Milwaukee Brewers, who had led the division for most of the season, with winning streaks in June and July, coupled with a pair of dramatic, late-inning wins against the Reds, and ultimately clinched the NL Central with a record of 85–77. The Cubs traded Barrett to the Padres, and later acquired Jason Kendall from Oakland. Kendall was highly successful with his management of the pitching rotation and helped at the plate as well. By September, Geovany Soto became the full-time starter behind the plate, replacing the veteran Kendall. They met Arizona in the NLDS, but controversy followed as Piniella, in a move that has since come under scrutiny, pulled Carlos Zambrano after the sixth inning of a pitcher's duel with D-Backs ace Brandon Webb, to "....save Zambrano for (a potential) Game 4." The Cubs, however, were unable to come through, losing the first game and eventually stranding over 30 baserunners in a 3-game Arizona sweep. Question: Who replaced Dusty Baker as the Cubs manager?
Output (English): Lou Piniella
