Rockies starter Jason Hammel is coming off a dismal start against the Royals.
In 3 2/3 innings, he surrendered six runs (five earned) on seven hits, including two Melky Cabrera homers, in a 16-8 loss.Nationals: Start me up
Livan Hernandez's rough start in Washington's loss over the Cubs on Thursday marked just the third time in the past 15 games that Nationals starters have allowed more than three runs. Ivan Rodriguez was a late scratch from the Nationals' starting lineup Thursday after straining his right oblique during batting practice and will be re-evaluated to see if a disabled-list stint is necessary. Worth noting
Rockies first baseman Todd Helton has 543 career doubles, tying him for 24th on baseball's all-time list. Nationals rookie Danny Espinosa's 16 home runs are tied for the most among Major League second basemen with the Brewers' Rickie Weeks.
