SAN DIEGO -- Clay Hensley came through for the San Diego Padres one day later than expected.
Hensley, scratched from his scheduled start on Saturday with an injury, pitched four strong innings against the Arizona Diamondbacks on Sunday after starter Chris Young left after one inning with a strained muscle in his upper back.
Hensley combined with five other relievers to hold the Diamondbacks in check, and with Mike Cameron's bases-loaded single in the 10th inning and four hits from Brian Giles, helped the Padres to a 2-1 win over Arizona.
The effort by Hensley helped relieve a depleted bullpen.
"He saved us," Padres manager Bruce Bochy. "He was a little sore, but he gave us a great effort."
Hensley was pulled from his start on Saturday after he felt pain in his left buttock. When Young had to leave the game, Bochy was concerned if his bullpen could make up the final eight innings.
"We would really have had to push some guys to give us nine innings," said Bochy.
Bochy approached Hensley to pitch in the emergency situation and he began to warm-up to see if he could be ready. After Jon Adkins threw two scoreless innings, Hensley entered the game.
"It was more discomfort than pain," said Hensley of his four-inning stint. "It feels pretty good."
Hensley allowed one unearned run and four hits with four strikeouts.
The win allowed San Diego to pull into a second-place tie with Arizona in the NL West at 62-62, four games behind first-place Los Angeles. The Dodgers come to San Diego for a three-game series beginning on Monday.
"It was definitely a big lift for our morale," Cameron said. "The Dodgers are chomping at the bit to knock the other teams out."
Cameron singled in the winning run with no outs after Giles started the rally with a double off Brandon Medders (5-3). Josh Bard followed with a single and Ben Johnson was intentionally walked to load the bases.
"I figured he was going to come in with a strike with the bases loaded," said Cameron. "I just tried to get a good swing on it."
San Diego won for only the fourth time in 13 games and is just 2-5 on a 10-game homestand.
The Diamondbacks have lost four of six.
"Their bullpen was good," Eric Byrnes said. "(Hensley) was (Saturday's) starter. He looked tough to me."
Rookie Cla Meredith (2-1) got one out for the win.
San Diego loaded the bases in the seventh on a one-out single by Dave Roberts, a double by Giles and an intentional walk to Todd Walker, his third of the game. But Miguel Bautista got Mike Piazza to hit into a double play.
"It's kind of frustrating because we've been saying if our starters can just give us chance to win, we're going to be in good shape," Diamondbacks catcher Johnny Estrada said.
Giles had three doubles and an RBI single in the fifth that tied the game 1-1.
The Diamondbacks scored in the fourth inning after Chad Tracy's leadoff single. Conor Jackson hit a slow roller with one out that shortstop Geoff Blum threw off balance into the stands on one hop.
The ball was ruled a hit, but Blum got a fielding error that allowed the runners to advance to second and third. Estrada followed with a sacrifice fly.
The Padres tied the score on Giles' single that scored Blum, who led off with a double.
Young faced three batters in the first inning and allowed a leadoff single to Byrnes before he picked him off first base. He retired the next two batters and did not come out for the second inning.
Bautista allowed one run and six hits over seven innings. Bautista walked six and struck out five. Bautista received his seventh no decision in nine starts.
Diamondbacks LF Luis Gonzalez hit his 538th career double in the sixth inning, to move within one of Al Simmons for 25th on the all-time list. ... Young tied his personal mark for shortest career start. The right-hander also only pitched on inning with the Texas Rangers last season on Sept. 7 at Minnesota. That start was also cut short by injury.
