Loyal Cubs fans might remember Petrick. He played for them just four years ago. The 27-year old from Morris, Illinois was selected by Chicago in the third round of the 2002 Amateur Draft. Petrick made a big splash in 2007. He started the year in Daytona and after six strong games was promoted to Double-A Tennessee. With the Smokies he was 1-1 with a 2.37 ERA in 18 games before moving up to the Iowa Cubs. After only nine games with Iowa, Petrick got the call every player dreams of hearing: he was going to “The Show.” Petrick stepped on the mound for the first time at baseball’s highest level on June 27, 2007 at Wrigley Field against the Colorado Rockies. He held opponents scoreless in five out of eight appearances. Since his time with the Cubs, Petrick spent 2008 with Daytona before being granted free agency. He pitched effectively for the Windy City Thunderbolts in 2009 until surgery ended his season. After a short stint with the Jackhammers last year, Petrick is ready to go with the Slammers.
