The right-hander looks for a fourth straight strong start while trying to help the Giants to a fifth consecutive win over the visiting Atlanta Braves on Tuesday night.
Vogelsong (1-1, 3.93 ERA) went 0-1 with a 7.71 ERA in his first four starts but is 1-0 while yielding two runs over 20 1-3 innings in the last three. He's given up a run and five hits in each of the last two, most recently Thursday over 7 1-3 innings of a 3-1, 10-inning victory at Dodger Stadium.
''I try not to concern myself too much with the wins and losses in my column,'' he said. ''As long as the team wins the game, that's the most important thing.''
The Giants (25-14) are 5-2 this season when the ball is in the hands of Vogelsong, who was re-signed to a one-year deal following 2013 when he went 4-6 with a 5.73 ERA in 19 starts and missed almost three months with a broken hand.
"A lot of my focus right now is not proving people wrong, but proving the people right that believe in me," he said. ''I know that there's certain people that had a big say in me coming back this year, and I know it was up in the air for a while. ... So I'm just trying to reward the people that wanted me back and prove them right.''
Prior to facing the Dodgers, Vogelsong lasted six innings and overcame four walks in a 3-1 win at Atlanta on May 3. However, he's 1-1 with a 7.59 ERA in two career starts against the Braves (21-16) in San Francisco.
Tim Lincecum yielded a run, two hits and struck out 11 in 7 2-3 innings and recently recalled Tyler Colvin homered and delivered a two-run triple as San Francisco won for the 14th time in 18 games, 4-2 over Atlanta on Monday.
Promoted from Triple-A on Saturday, Colvin went 0 for 1 with a walk in his previous two games with the Giants.
B.J. Upton homered and had two of the three hits by the Braves, who have totaled five runs while going 0-4 against the Giants this season. They've also been outscored 27-6 during a four-game slide at San Francisco.
While Upton is 6 for 19 (.316) with two doubles, a triple and 10 strikeouts versus Vogelsong, Freddie Freeman is 5 for 13 with two homers against him.
Scheduled Atlanta starter Mike Minor (0-2, 6.97) allowed two runs in six innings of a 2-1 loss to the Giants on May 2 in his season debut that dropped him to 2-1 with a 2.93 ERA in five starts in the series. He yielded six runs and 11 hits in 4 1-3 innings of a 7-1 defeat to St. Louis on Wednesday.
"I'm sure a lot of people are going to speculate, 'What's wrong with Minor?'" said the left-hander, who missed the first month with shoulder tendinitis. "It's just my second start up here. One was good. One was not so good."
San Francisco's Michael Morse is 6 for 12 with a homer and two doubles versus Minor, but 2 for 24 in his last seven contests.
