The San Francisco Giants snapped out of a downward spiral before the All-Star break and look to continue the turnaround when they begin a seven-game road trip at the Miami Marlins on Friday. The Giants, who have scored fewer than two runs nine times over their last 20 contests (7-13), triumphed in five of their last nine and stand one game behind the first-place Los Angeles Dodgers in the National League West. Miami comes in with four straight losses and is 10-20 in its last 30 contests.Giancarlo Stanton, who leads the NL in RBIs (63) and is tied for the top spot in home runs (21), tries to lead the Marlins out of their own offensive doldrums. Miami, which split four games at San Francisco in mid-May, has produced only 12 runs in its last six games. Second baseman Marco Scutaro (back), the 2012 NL Championship Series MVP, made his season debut last week and could help boost the Giants' offense.TV: 7:10 p.m. ET, CSN Bay Area (San Francisco), FSN Florida (Miami)PITCHING MATCHUP: Giants LH Madison Bumgarner (10-7, 3.47 ERA) vs. Marlins RH Nathan Eovaldi (5-4, 3.61)Bumgarner snapped a three-game losing streak his last time out despite allowing four runs and 10 hits over 6 1/3 innings against Arizona.
