Despite injuries to key offensive players over the past few weeks, the one consistency this season with no injuries was the starting rotation for the San Francisco Giants, well that was until tonight’s series opener against the Colorado Rockies.

Matt Cain, who pitched fantastic in his last start on Saturday against the Chicago Cubs was forced to leave the game against the Rockies due to a strained right hamstring with two outs in the second inning.

To make matters worse, Cain’s replacement, Albert Suarez took a ball off his left leg with one out in the third inning; however Suarez stayed in the game.

Tyler Chatwood was solid for the Rockies, as he went seven innings, allowing four hits and the Rockies defeated the Giants 5-2 at Coors Field.

With the loss, the Giants saw their 10-game winning streak versus the National League West come to an end. It was the Giants longest winning streak versus the division since winning 10 in a row in August of 1982.

Nolan Arenado, Charlie Blackmon and Trevor Story each drove in runs with doubles, as the Rockies took the opener in a game that was delayed 42 minutes at the start due to weather.

Suarez pitched five innings, allowing three runs and lost for the first time in his major league career. The right-hander did get his first major league RBI on a fielders choice in the top of the third inning.
