Dickerson had a career-high four hits, including the go-ahead RBI single in San Francisco's four-run 10th inning as the Giants recovered from giving up a three-run lead in the ninth to beat the Colorado Rockies 8-4 on Tuesday night.
Yastrzemski homered and doubled among his three hits and had three RBI to help the Giants win their fourth straight and seventh in the last eight.
"You could put (Austin) Slater in there," Giants manager Bruce Bochy said. "They have all really been a lift for this club offensively and they're really doing a good job on defense, too. I'm proud of them. This is a tough road trip."
Yastrzemski was brought up in late May and Dickerson has been with the Giants since mid-June after being acquired from San Diego. Slater joined the team July 1 and already has a pinch-hit grand slam.
"It's been a lot of fun," said Dickerson, who is batting .400 (24 for 60) in his 19 games with the Giants. "I've actually never really hit well here, this is a first for me. I'm seeing good pitches to hit, I mean, (Brandon) Crawford is hitting behind me and he annihilated them (Monday), so I knew I was going to see some good pitches to hit."
Trailing 4-1 going into the bottom of the ninth, Colorado rallied against Giants closer Will Smith (3-0). Story connected for his 21st home run to start the inning. One out later, Daniel Murphy singled and Desmond followed with a drive that reached the center-field seats to tie it. It was the second blown save for Smith in his last three chances after converting 23 straight to start the season.
But the Giants answered against Rockies closer Wade Davis (1-4) in the top of the 10th. He issued two one-out walks before Dickerson singled to right as the Giants regained the lead. Brandon Crawford followed with an RBI single and Bryan Shaw relieved Davis. Yastrzemski singled to drive in another run before the Giants scored an unearned run on third baseman Nolan Arenado's fielding error.
Mark Melancon pitched a scoreless 10th for the Giants.
Desmond said he and Murphy were motivated going into their at bats after seeing Story connect and even though the rally went for naught he's hopeful it will return dividends in the long run.
"We both looked at each other and I said, `Hey man, you think a couple of old guys can fight a little bit harder.' And he goes, `Yeah, let's go out and fight' em,' and we were able to tie it up there. Unfortunately, we came up short but that grit is going to pay off in the end."
The Giants took a 2-0 lead in the second inning when Dickerson led off with a single and scored one out later on Yastrzemski's double. Yastrzemski came home on Joe Panik's single.
Dickerson's RBI single in the eighth made it 3-1 and Yastrzemski's homer off Chad Bettis in the ninth put the Giants up by three runs.

WHAT A CATCH
Giants center fieder Kevin Pillar took away extra bases from pinch-hitter Tony Wolters in the bottom of the eighth inning with a spectactular diving catch. Wolters, leading off the inning, sliced a sinking liner to center. Pillar, playing back, made for the ball on a dead run and then dove for it, snaring the ball as he tumbled on the ground and then holding his glove up for the umpire to see that he had made a clean catch. He made another diving catch in the bottom of the 10th, taking away a base hit from Story.
MAKING A MOVE
