Jon Lester is set to start for the Washington Nationals at Wrigley Field after spending the past six seasons with the Chicago Cubs. The 37-year-old lefty is 0-1 with a 2.25 ERA in three starts for his new team. Lester was a two-time All-Star for the Cubs and went 3-1 in the 2016 postseason as they won a most elusive championship. Lester pitched in relief in Game 7 of the World Series and his catcher was David Ross, now the Cubs manager.
