San Francisco Giants vs. Washington Nationals preview
The Nationals roll into Oracle Park carrying the weight of a disappointing season, sitting 23 games under .500 while the Giants fight to stay relevant in a competitive NL West race.
Washington's Jake Irvin takes the mound with modest career numbers but has been serviceable this year, facing off against Giants rookie Carson Whisenhunt who's making just his second career start with limited major league experience.
The Giants hold a clear pitching advantage with a team ERA nearly two runs better than Washington's league-worst 5.37 mark, though their offense has been equally inconsistent this season.
San Francisco's bullpen has been more reliable than their struggling counterparts, converting saves at a better clip despite both teams dealing with late-game issues this year.
Oracle Park's marine layer could play a factor in this Friday night matchup, especially with both lineups posting middling power numbers and the total set at a reasonable 9 runs.
The Giants desperately need to take advantage of home field against one of baseball's weaker road teams if they want to make any serious playoff push in the season's final months.
