Diamondbacks 2, Nationals 3: Walk-off loss, again...

Trevor Cahill continued his resurgence in the Diamondbacks' starting rotation, going 6.1 innings allowing just two runs against a quality Washington offense.

The Nationals' starter was just better. Tanner Roark went seven strong innings, tossing up zeroes along the way and fooling the Arizona hitters.

Ender Inciarte and the Diamondbacks were able to get two in the eighth with a home run off of Washington reliever Tyler Clippard to tie the game up. But the Nationals fought back and scored in the ninth for their fourth walk-off win in five games.

Cahill breezed through the first inning, but ran into trouble in the second against the heart of the Nationals' order. With one out already recorded, Cahill walked Ian Desmond then gave up a base knock to Bryce Harper. Desmond then stole third base and scored on a Wilson Ramos fielder's choice to put Washington up on the board first. Cahill eventually got out of the inning when he struck out opposing pitcher Tanner Roark.

The D-backs tried to answer the bell in the ensuing half inning, threatening with a couple runners of their own, but to no avail. With runners on first and second with one out, David Peralta flied out to center field, and Mark Trumbo grounded out into a fielder's choice to retire the side.

Things looked as though they'd change in the top of the sixth for Arizona. Cliff Pennington singled to lead the inning off; and despite a Peralta fly ball out, Mark Trumbo kept the inning rolling with a single to right to advance Penny to third. HERE WAS THEIR CHANCE. Yet, like the rest of the road trip, there'd be no offense. Roark induced a ground ball double play off the bat of Miguel Montero to end the inning.

The Nationals rode the momentum into the following half and scored right away. Two straight doubles from Asdrubal Cabrera and Jason Werth extended Washington's lead to two. Cahill then walked LaRoche and got Desmond to fly out to right. Hell of a play by Aaron hill to keep a run from scoring, dove to stop a Harper ball through hole to his right and got the runner at second. Ramos then grounded out to end the inning, which meant Cahill did a great job to limit the damage.

After another unsuccessful inning for the D-backs, Cahill was sent back out in the seventh. He allowed one to reach and got one out before Kirk Gibson pulled him from the game.

Jordan Pacheco walked to get on base for Ender Inciarte, who parked it over the right field fence to tie the game up at two. It must have just been a change of scenery out on the mound for the D-backs to get the offense going. For seven innings, Roark shut Arizona down. But right when Tyler Clippard came in it seemed to change. Even so, the D-backs couldn’t do anything else in the inning when Matt Williams went to Drew Storen.

Brad Ziegler got three outs in the eighth with relative ease. Evan Marshall came on to pitch in the ninth for Arizona after another quick top half.

Bryce Harper led the inning off with a single, and was advanced to third two batters later on a Kevin Frandsen single. To win the game, Anthony Rendon pulled a single down the left field line to score Harper from third.

The go-getters: Ender Inciarte (30.6 %), Cliff Pennington (20.3 %).

Not so much: Miguel Montero (-22.6 %).

The Diamondbacks will try to avoid the sweep tomorrow when Wade Miley takes on Gio Gonzalez.

GDT: Congrats to 'skins.
