So games Seranthony Dominguez resembles the great Mariano Rivera, and some games he looks like just another stumblebum reliever.

If only Phillies fans could predict which they’ll get on any given night.

David Peralta hit a walk-off homer in the 14th last night, cutting the first-place Phillies’ lead in the National League East to one game over the Braves.

“I feel bad for Jake,” Dominguez said through the Phillies’ interpreter.

Dominguez is 1-3 with a 2.45 ERA and 12 saves in 36 appearances this season. He is a big reason the Phillies are a first-place team in the second week of August.

But Dominguez also is 0-1 with a 7.11 ERA in his last seven appearances.

He blew a save Sunday, when he allowed a game-tying home run to Justin Bour in the seventh inning at Citizens Bank Park.

And last night he was given a 2-0 lead in the 9th and blew another save and ultimately allows the D-Backs to win in 14.

“This is not his best. I’m not blind,” Phils manager Gabe Kapler told “The reality is he’s not pitching his best right now. But we are not wavering in our confidence in him whatsoever. We cannot wait to get him back out on the mound because we understand how good he is and the talent will prevail.”

“I feel normal. I feel fine,” Dominguez said about pitching on no rest. “I feel healthy, strong. Sometimes I don’t get the results that I want. But I have to keep working hard to get to that.”

“The majority of the people that I’ve spoken with have given me some advice, which is to save my bullets,” Dominguez said about remaining strong for the final weeks of the season. “Try to throw just a few pitches when I do a bullpen or when I’m throwing. And during the game, try to get guys out quick. We want to save our bullets for October and the playoffs.”
