How to Watch Boston Red Sox at San Francisco Giants (June 21): Stream MLB Live, TV Channel

Two teams with playoff ambitions will battle this weekend as the San Francisco Giants host the Boston Red Sox. 

A pair of competitive teams will take the diamond today, as the Boston Red Sox and San Francisco Giants match up. As we enter the back half of the season, these are the types of series that can make all the difference long-term. Boston barely won the opener of this series, which gave a glimpse into just how exciting these next two games could be. The Red Sox have put together a solid season at 40-37 on the season, but that’s only good for fourth in the American League East. It’s a loaded divisional race, so every series is of extreme importance. They’re 18-20 on the road this season, so this week provides an opportunity to bring that up to .500 to this point. At 42-34, the Giants are second in the National League West, behind only the Los Angeles Dodgers, who are arguably the best team in baseball. They’re 23-14 at home this season, which should be a huge advantage in this series.

This is truly a battle between teams that could make a significant splash in the postseason. Boston has made changes of late but is still competitive, while San Francisco continues to load up with talent. The blockbuster trade of Rafael Devers looms large in this game, as he takes on his former team immediately following the surprise trade.

Following this contest, these two teams will match up one more time on Sunday afternoon before going their separate ways. At that point, the Red Sox will remain on the road with the Los Angeles Angels being next on the schedule. Meanwhile, the Giants will stay at home to host the Miami Marlins next.
