The Mariners are entering this series off a loss and lost their 3-game series against the Athletics 2-1 in their last series.

This is the 3rd game of a 4-game series with the Rangers on Saturday with the 2nd game of this series still to be played on Friday. The Mariners won the 1st game of this series on Thursday.

The current betting odds have the Mariners listed as a slight underdog in this game according to Draftkings Sportsbook. The Rangers have looked good in their games this season with their 57-53 record overall which has them right in the middle of the AL West and in the Wild Card race. They haven't been a good road team though with their 23-33 road record this season. Meanwhile, the Mariners have looked good in their games this season with their 58-52 record overall which has them right near the top of the AL West in the Wild Card race. They have also looked better in their own ballpark this year with their 29-24 home record. The Rangers have been the hotter team lately as they are 7-3 in their last 10 games while the Mariners are only 5-5, but the Mariners have the much better offense and have already taken the 1st game of this series. The Mariners are going to have Castillo on the mound here and he has looked great this season. He is 8-6 with a 3.19 ERA and the team has had a ton of success with him lately. He is coming off another great start in which he only gave up 1 earned run and the team has won 6 of their last 7 games with him starting too. The Rangers are going with deGrom in this one and he has also looked great this season. He is 10-3 with a 2.55 ERA, but lately the team hasn't been having success with him. They have actually lost 3 of their last 4 games with him starting and he is also coming off a bad start in which he gave up 5 earned runs. This is a big series for the Mariners to get ahead in the Wild Card race and Castillo has looked a lot better at home this season too so the Mariners can take advantage of the Rangers who have been a bad road team all season. The best way to place a bet here is on the Mariners to win this game.

“Anytime you have a chance to add somebody of Merrill Kelly’s stature to a rotation [you do it]. We're thinking about how this plays, not only for the rest of the season, but into the postseason. He is somebody with a pedigree that fits right in. We’re fortifying what has been a strength for us this year and continuing to build upon that as we try to complete this roster.” - Ross Fenstermaker on the team acquiring Merrill Kelly. 

“Naylor is one of the toughest outs in the league. Getting those two guys is going to be a big add for us. It’s been a fun couple of days seeing us add like that.” - Cal Raleigh after their win against the Rangers in their game on Thursday.
