Neither Valaika, nor his manager, Bud Black, appeared all that surprised at the 416-foot shot to center off Urias, who had given up just five homers in 87 1/3 career innings pitched to that point.
"It was a ball up and out over the plate, and Pat squared it up," Black said. "[Urias] is a good pitcher, and has good stuff. But when you throw the ball up in the strike zone, you're in peril."
"It was just a curveball that I left there," Urias said. "He hit it well. What else can I say?"
Seven of Valaika's 11 hits this season have been for extra bases, including that shot off Urias, which was the first homer the left-hander had given up in 20 1/3 innings in 2017. But he's not trying to fill Story's shoes offensively, even if Story has slumped to open the season.
"I just try to be myself, whatever situation comes up, I don't try to do anything different," Valaika said. "I just try to be the same player every day."
The way he hit on Sunday, and with a .585 slugging percentage in his limited playing time this season, Valaika's teammate-given nickname of "Patty Barrels" may be here to stay.
