Manny Machado hit a walk-off single on the first pitch of the bottom of the 10th inning, sending the Padres to a dramatic 7-6 victory over the Braves on Tuesday night at Petco Park. Mason Miller held Atlanta scoreless in the ninth, then did so again in the 10th -- marking the first time he’d completed two innings as a Padre and setting the stage for Machado’s walk-off. Here’s some instant reaction from Petco Park: **Here comes the power from Tatis** Through the first three months, plenty has been made about Fernando Tatis Jr.’s power outage. But you know what? He’s been pretty good otherwise. Essentially, he’s a five-tool player who’s been missing one of those tools all season. But the power is still in there. Clearly. Tatis tied the game at six with his third home run of the season in the bottom of the seventh inning. He got his hands through on a sinker that caught the inside corner of the plate from Carlos Carrasco. Then, he launched it a Statcast-projected 410 feet to straightaway center field. That’s no small feat at night at Petco Park. But Tatis, despite his struggles in the power department, is clearly capable. “The home runs will come,” Tatis said. “And if not, whatever. We’re here to play good baseball. Obviously homers are a part of it. But I’m going to keep going out there, get on base for the team, good at-bats out there, and just try to hit the ball hard, all around the field.”
