"That changed the whole complexion of the game when you have to go to your bullpen in the third inning," Padres manager Bud Black said. "Our guys did a good job of fighting through it. I've mentioned over the last three weeks I've sensed a little more continuity. We've tightened some things up."
The four-game winning streak is the longest of the season by the Padres. Over the last week the club has won five of its past six games and with 10 hits Tuesday, the Padres have 55 total hits during that span.
"We've had a lot of different guys step up and get big hits, that's what you're supposed to do," Padres third baseman Chase Headley said. "A lot of guys contributing, it's nice to see that. You come out and you keep playing, but you definitely enjoy winning, it's been a nice little stretch for us."
Headley and Yonder Alonso combined to drive in five of the Padres' nine runs while Cameron Maybin and Alexi Amarista each collected two hits.
Cashner felt the pain while he was warming up to pitch his third inning. The 25-year-old signaled to the dugout and was escorted out shortly after. After the game club doctors confirmed the injury was to his lat, not his shoulder.
"It's a setback," Cashner said. "But we'll make it through and figure out a lot more tomorrow."
Ross Ohlendorf replaced Cashner in the third and earned the win by pitching 2 1/3 innings and surrendering three runs on four hits. Tuesday marked the first appearance for Ohlendorf since he returned to the bullpen after starting two games in June and allowing eight runs in 8 1/3 combined innings.
All of the damage charged to Ohlendorf was done after he left the game in the fifth with the bases full and one out. Nick Vincent took over and struck out Justin Upton before serving up a grand slam to Jason Kubel.
Vincent, Dale Thayer, Joe Thatcher and Luke Gregerson combined to finish off the game for the Padres with the bullpen tossing seven innings Tuesday.
"There was that one huge pitch that got them back in the game, but after that they all did a nice job," Black said of his relievers. "It was good to see."
Back in the first inning, the Padres looked ugly at the plate in their first glimpse of Bauer, with all three batters striking out swinging on five pitches or less. But in the second frame, Alonso smacked the first pitch he saw into the right-field bleachers with a runner on to give the Padres a 2-0 lead.
"He had a tremendous first inning but we started to see the ball better," Black said. "His control was a little bit spotty but it wasn't unexpected for a guy making his first home start."
After Cashner's unexpected exit in the third, the Padres exploded for five runs in the fourth off Bauer to knock the rookie out of the game.
Ohlendorf drove in the first run of the inning with an attempted squeeze bunt that Bauer mishandled for an error. Amarista then followed with a RBI single before Headley opened the floodgates with a bases-loaded double to plate three more runs and put the Padres ahead, 7-0.
"I felt like as the game went on, guys started to figure him out because he's unorthodox to say the least. There's a lot of stuff flying at you," Headley said. "I think the biggest thing that got him was he lost control, he put himself in some tough positions. When you do that in the big leagues, that's going to hurt you."
Four innings later, Jesus Guzman hit a pinch-hit solo shot in the eighth to cap the Padres' offensively charged evening.
"You have to give them some credit, I think they're feeling it," D-backs manager Kirk Gibson said. "You can see they're very aggressive up there. We're going to have to be very careful the way we throw the ball to them."
