Giants vs Mariners Odds, Lines, and Spread

The San Francisco Giants begin the new season against the Seattle Mariners on Thursday at 10:10 pm ET at T-Mobile Park.

Giants and Mariners are playing each other in a game with a total of 8.5 points. Seattle's Marco Gonzales is coming off a stellar season with 7-2 record and 3.10 ERA. San Francisco has won seven of the last ten interleague games.

Tommy La Stella is injured and is day-to-day. Buster Posey is back in the big leagues for the first time since September 29, 2019. Scott Servais is running out his young lineup against Kevin Gausman. The Mariners have a poor record against the 30-year-old. The last time Poseys had at least 500 at-bats was in 2016.

Kyle Seager is a player that stands out entering Thursday's lid-lifter. Kyle slashed .241/.355/.433 and played in all 60 games at the hot corner last season. Seagers has hit at least 20 home runs every full season since 2012.

Seattle is a home underdog against Giants. Seattle won nine straight Opening Day games between 2007-2015. The last five openers Seattle went 2-3. Gonzales is better than Gausman.
