Some weeks, the two-start pitching landscape is a lot like California during the gold rush -- just drop your pan into any old river, and you'll find something valuable and shiny. 

Week 21 (Aug. 21-27) is not one of these weeks, at least not if you're looking on the waiver wire. By my count there are only 17 starting pitchers under 50 percent ownership with two starts, and it's hard to get excited about any of them.

Edwin Jackson has been a surprisingly useful fill-in for the Nationals, posting a 2.92 ERA in six starts, but he has the face the Astros in his first start, a team that combines huge power with the best strikeout rate in baseball. That's not exactly what you want to target. Jackson may pitch well enough against the Mets to make up for it, but you don't want to pin your hopes and dreams on that. 

Among the low-owned group, the most interesting options are also two of the youngest: Nick Pivetta and Tyler Skaggs. Pivetta has huge strikeout potential, but has huge blow-up potential against good Marlins and Cubs lineups. I would lean toward Skaggs, who has a 3.63 ERA for the season, including a 2.93 mark since returning from the DL. The problem is, he has topped six innings just once in his last three starts, and has to face those same Astros in his second start. These two are the "Break Glass in Case of Emergency" options. 

Higher up the scale, things get more interesting. Carlos Rodon (vs. MIN, vs. DET) should already be universally owned, but he's still out there in nearly one-fifth of CBSSports.com leagues. Go get him and start him, as he has shown his ace potential since returning from the DL. Dan Straily (at PHI, vs. SD) might have the best pair of matchups possible, and he makes for a solid fill-in, as does Patrick Corbin (at NYM, vs. SF). Neither has been all that reliable of late, but if they hit, they can put together plenty of strikeouts against these lineups. 

Again, it isn't the best group ever. Sorry. Scott's not here this week, but this still isn't my fault. Don't blame me. Still, you can find value here if you know where to look. You might have to roll the dice some, but you can't win without a bit of risk. At this point in the season, aim for upside. That's what we have here.
