Ryan Feltner has a 6.75 ERA at Coors Field this season with a brutal 1.65 WHIP, allowing a .325 BA. The Rocks have lost his last 4 starts to the tune of 7 RS, 24 RA. He got crushed in his earlier start vs SFG (7 H and 5 ER in 4 IP). Hayden Birdsong has presented himself well beyond his 22 years with Los Gigantes and I like him in this spot. SF 5-3 vs COL this season.

If Colorado's Ryan Feltner at 1-9 with a 5.36 ERA isn't the worst current starting pitcher in the majors, I'm not really sure who is. He's 0-2 with a 6.75 ERA at home. Rox closer Victor Vodnik is likely unavailable. Giants rookie Hayden Birdsong has been very solid through four big-league starts and Colorado hasn't seen him. Perhaps some desperation here for SF to avoid an embarrassing sweep considering it has wild card hopes.
