It's not clear what kind of pitcher Fantasy owners have in Patrick Corbin this year. The Diamondbacks' lefty has been throwing harder than he did last year, dialing his fastball up to 92 mph on average -- a tick above last season's mark -- but he's not been the control artist that we have come to know.

With not many quality two-start pitchers available on waivers for Fantasy Week 4 (April 22-28), Corbin is worth a one-week trial. Even if he is wild, he will face a Giants lineup that is not known for its patience, as well as the Rockies, but away from Coors Field. With a 45 percent ownership rate on CBSSports.com, Corbin should be available in a wide swath of mixed leagues.
