This is it. Maybe it's too early to say that a certain set of games is a defining stretch for a baseball team, but the Pirates need some wins against the Reds this weekend. Three straight losses against the Brewers has really taken the air out of the tires on the Pirate bandwagon, but Zach Duke (the Pirates' best pitcher this year) goes against Bronson Arroyo (a guy the Pirates have hit well recently) at PNC Park tonight. Nate McLouth makes his return to the starting lineup tonight, and hopefully he can give a jolt to an offense that was depantsed by Yovani Gallardo two days ago. If this year is going to be any different at all than past years, the Pirates need a win tonight.
