Chris Archer is on his way to a 20-lose season and has shown no signs of reverting back to last season's All-Star form. His ERA hasn't been under 4.00 since his second start and he's given up 20 homers after surrendering 19 last year. Archer is 0-6 in his last seven starts.

Archer has allowed four runs or more in five of his last six starts. His biggest trouble has come on the road where he's 3-6 with a 6.75 ERA. Now he's pitching in the best hitter's park in the majors against a foe that ranks third in runs and batting average. The Rays are a bad grass team losing 22 of the past 30 times they've played on a natural surface.

Tampa Bay ranks 26th in runs and 27th in batting average. The Rays have scored less than five runs in 11 of their last 15 games. They have a losing record versus lefties and are going against southpaw Jorge De La Rosa.

De La Rosa has turned his season around so his season ERA should be discounted. De La Rosa has turned in six straight quality starts. He has a history of pitching well at Coors Field, where he's allowed just one run in his last 15 innings there. He is 3-0 this season with 1.93 ERA in day games.
