The Diamondbacks are still more about potential than production. They have a terrible 15-33 home record. But in my view this matchup makes for a good value play backing the home underdog with promising Archie Bradley against Brandon McCarthy.

McCarthy missed about 14 months following elbow surgery. This is the 33-year-old's third start since returning from the DL. McCarthy has gone just five innings during his previous two outings. The Diamondbacks should be somewhat acquainted with McCarthy since he made 22 starts for them in 2013.

It's too much to expect McCarthy - a middle-of-the-road type starter - to go deep into the game while holding the Diamondbacks down at hitter-friendly Chase Field. The Dodgers are missing one of their key players, too, with outfielder Joc Pederson on the DL.

Bradley has a high ceiling. The 23-year-old has given up three runs or fewer in four of his last five starts. Yet he's somewhat under-the-radar because he only won one of those games.

The Diamondbacks have won seven of Bradley's 10 NL West Division starts.

(Editor's note: In addition to this free play, Stephen Nover has his Parlay of the Week - where both sides are guaranteed - going today. Stephen has won 10 of his last 14 premium and free baseball plays.)
