SAN DIEGO -- The light-hitting San Diego Padres found a way to win without having to get a hit.
"You have to hang around long enough and stay close and things like this will happen," Padres manager Bud Black said.
The Rockies held a one-run lead when Brothers walked the bases loaded with two outs. Facing Yasmani Grandal, Brothers unleashed a wild throw. As Rosario retrieved the pitch, he turned and threw wildly back to Brothers covering the plate.
"I didn't know (if I could score) but I knew was going to go and make them throw me out," Smith said. "I was that situation where you're the winning run and you're already halfway there, and the ball just got by the pitcher, so they have to make at least a decent play to get me out."
Brothers (1-2) allowed a game-winning homer to Brandon Crawford on Sunday in San Francisco's 5-4 win in 10 innings.
"I don't have an excuse," Brothers said. "As hard as it is, I'll put it behind me and get my butt back out there and get the job done for these other guys."
Said Rockies manager Walt Weiss: "He struggled with his command, and his slider was bouncing well in front of the plate. He wasn't getting swings on his slider like he usually does."
"It was a lucky bounce for us and we haven't got any in two years, so we deserved it," said Yonder Alonso, who drew the walk that loaded the bases in the eighth.
San Diego is last in the National Leagues in runs scored with 33 and near the bottom in batting average.
Rosario hit a two-run homer off Eric Stults with a drive into the left-field seats in the fifth inning to give Colorado a 4-0 lead.
Rockies rookie Jordan Lyles gave most of the lead back in the bottom of the inning when he allowed three runs.
"That was a big part of the game by bouncing back and getting back in it with clutch hits," Black said.
Lyles allowed three runs on six hits over five innings.
The Rockies lost for the sixth time in eight road games.
Rockies right fielder Michael Cuddyer was injured on Amarista's hit when he fell backward attempting to catch the ball as it went over his head. Cuddyer crashed hard into the right field message board and stayed slumped on the warning track before being removed from the game a few minutes later with a bruised right elbow.
Stults allowed four runs -- three earned -- on nine hits over five innings.
