Rays vs Giants Prediction
The current betting odds have the Giants listed as a slight favorite in this game according to Draftkings Sportsbook. The Giants haven't looked great in their games this season with their 59-62 record overall which has them right in the middle of the NL West. They haven't looked that great in their own ballpark either with their 29-31 home record this year. Meanwhile, the Rays haven't looked great in their games this season with their 59-63 record overall which has them right near the bottom of the AL East. They haven't been a great road team either with their 27-33 road record this season. Both of these teams are trying to get themselves back into the Wild Card race but neither team has looked great lately, both going 4-6 in their last 10 games. The Rays are going to have Boyle on the mound in this one and he has looked great this year. He is 1-2 with a 3.82 ERA, but the team hasn't had a ton of success with him starting. He is coming off a bad start in which he gave up 6 earned runs and the team has lost 4 games in a row now with him starting. The Giants are going with Roupp in this one and he has looked good this season too. He is 7-6 with a 3.11 ERA and he hasn't been giving up many runs lately. He is coming off another great start in which he gave up no runs and the team has had a ton of success with him too, winning 5 of the last 6 games he started in. The Giants just got swept in their last series against the Padres and they have been in a big slump lately, but the Rays haven't looked any better lately so the Giants can take advantage of this pitching matchup to bounce back at home. The best way to place a bet here is on the Giants to win this game.
