(Sports Network) - Barry Zito tries to avoid his third straight loss this afternoon when the San Francisco Giants attempt to win their first series at Turner Field since 1997 in the finale of their four-game set with the Atlanta Braves.

Zito lost for the third time in four starts on Wednesday in Houston, as he allowed six runs and four hits in 5 2/3 innings, dropping him to 6-15, while raising his earned run average to 5.73.

The 30-year-old left-hander has faced the Braves twice in his career and is 1-1 against them with a 4.50 ERA. However, he hasn't faced them since 2005 when he was with Oakland.

San Francisco can only hope Zito gives it the kind of effort that Tim Lincecum did on Sunday, when the electric right-hander surrendered a run and three hits in 7 2/3 innings of the Giants' 3-1 win.

Lincecum (13-3), who exited his last start after being hit on his right knee with a line drive, showed no ill-effects of the injury, as he struck out 10 and walked four batters.

Travis Ishikawa belted his first major league home run and Emmanuel Burriss was 2-for-4 with a double and an RBI for the Giants, who have won two of three on the heels of a four-game losing streak.

Rookie Charlie Morton (3-7) pitched well but was credited with the loss for yielding three runs on seven hits with two walks and fanning half a dozen in his six-inning start for the Braves, who have lost six of seven.

Atlanta will pin its hopes today on righty Jorge Campillo, who is 7-5 with a 3.09 ERA. Campillo lost for the first time since July 7 on Wednesday against Chicago, as he was hit for five runs and seven hits in five innings.

Campillo will be making his first-ever start against the Giants.

The Giants won two of three meetings with the Braves in San Francisco from August 4-6 and are 5-2 over their last seven overall matchups with Atlanta.
