The Phillies will send Cole Hamels to the mound. He has not lost a game since Aug. 2 and will be looking for a seventh straight quality start and his 15th win. Hamels currently sports a 3.04 ERA, ninth-best in the National League.
Colorado will counter with Tyler Chatwood, who is in his first season with the Rockies. Chatwood has struggled through seven starts and seven relief appearances, posting a 5.53 ERA and a 4-4 record.
The Phillies' five-year streak of winning the NL East will expire this year, as many of the team's high-profile players have struggled with injuries. However, they are now just four games under .500, the closest they've been to the break-even mark since June 26.
Saturday's game will start at 7:05 ET, and can be found on CSN.
