Quietly under-the-radar, Rockies pitcher Tyler Matzek is beginning to live up to his one-time vast potential. Matzek is 3-1 with a 1.23 ERA in his last four starts. He has given up just four earned runs in his last four starts spanning 29 1/3 innings. Going back to his past six starts, Matzek has a 2.57 ERA and 1.12 WHIP.

Matzek has shown he can pitch well at hitter-friendly Coors Field losing only once in his last three starts there while posting a 1.19 ERA.

Let's contrast this with Dodgers starter Dan Haren, who has a 10.23 ERA during his last four starts at Coors Field. Haren last pitched at Coors on July 5 and was hammered for eight runs in 5 1/3 innings.

Haren, who turns 34 tomorrow, has thrown 212 pitches in his last two starts. That's the most he's thrown in consecutive games since back in May.

The Rockies have Justin Morneau and Michael Cuddyer back in their lineup. Cuddyer won the National League batting title last year. Morneau is trying to win it this year. Colorado can hit at home averaging 6.5 runs in their last 14 games at Coors.
