SAN DIEGO — The Rockies walked the high-wire Monday night at Petco Park. Their pitchers teetered and tottered. They walked 11 Padres batters. Count ’em, 11. But somehow, someway, the Rockies held on to win 5-4, notching their fifth consecutive victory. The Padres loaded the bases in the ninth against Jalen Beeks on three walks, but Beeks got Manny Machado to ground into a 5-4-3 double play to end the game. “That was exhilarating, for sure,” a frazzled but happy Rockies manager Bud Black said.
