The Rockies extended the best start in franchise history by taking two of three from slumping Cincinnati. They have the NL's best record at 28-17.
Freeland (5-2) remained unbeaten on the road, giving up four runs — three earned — in 5 2/3 innings. Joey Votto and Scott Schebler homered off him in the sixth. The left-hander is 3-0 in five road starts.
Freeland also doubled and hit his first major league homer off Arroyo (3-4), connecting on a 71 mph pitch for a drive that carried over the wall in right field. Carlos Gonzalez, DJ LeMahieu and Pat Valaika also had solo shots off Arroyo, who has given up 15 homers — second-most in the NL.
