Arizona at Washington

The Washington Nationals are the surprise of the early season, but maybe they shouldn't be so surprising. Jordan Zimmerman developed into a top-of-the-rotation pitcher last season despite his 8-11 record, as he pitched to a stellar 3.18 ERA. He has improved upon that this season, entering this contest with an ERA of a microscopic 1.33. Trevor Cahill was an 18-game winner in the AL in 2010 and without the DH in the NL he is poised to put up strong numbers again this season. The D-backs have played to a 7-1 UNDER mark in their last eight on the road as a dog of +110 to +150. Washington's strong pitching has led them to a 28-11 UNDER mark in their last 39, which includes 10-2 when posted as a home favorite. Play on the UNDER.
