The Pirates are entering this series off a win and lost their 3-game series against the Colorado Rockies 2-1 in their last series. They enter this game with a 39-39 record overall and have a home record of 20-19. This is the 1st game of a 3-game series with the Mariners on Tuesday and they have Monday off as a day of rest.

The current betting odds have the Mariners listed as a slight favorite in this game according to Draftkings Sportsbook. The Mariners have looked good in their games this season with their 40-39 record overall which has them right at the top of the AL West. They haven't been a great road team though with their 18-20 road record this year. Meanwhile, the Pirates have looked good in their games this season with their 39-39 record overall, but that record has them right near the bottom of the NL Central. They have looked better in their own ballpark with their 20-19 home record this season. Neither team has looked great lately as both are 4-6 in their last 10 games respectively, but the Mariners do have the better pitching matchup to take advantage of. Kirby is on the mound for the Mariners in this one and he hasn't looked great this season. He is 5-7 with a 4.10 ERA, but lately he hasn't been giving up as many runs. His team has still lost 3 games in a row now with him starting, but he gave up 3 earned runs in his last start and hasn't been getting lit up on the mound. The same can't be said for the Pirates starter though. The Pirates are going with Keller in this one and he hasn't looked good this season at all. He is 5-4 with a 4.92 ERA and lately he has looked terrible in his starts. He only gave up 1 earned run in his last start, but that hasn't been a common theme for him this year. He has had a lot of starts in which he gave up over 5 earned runs and even his team has still lost 2 of their last 3 games with him starting. The Pirates have been really up and down all season and the Mariners should have the slight edge here with the better starter and bullpen. The best way to place a bet here is on the Mariners to win this game.

“Cal did a good job - like, [with two strikes] I think slider right away, probably. And he went to curveball a few times with two strikes. I think that was smart, looking back afterwards. If guys are kind of in-between bat speed you don’t really want to give them a gift, something at 90 or whatever. So the curveball at 81, if you’re keeping the same hand speed and everything. I think it does a good job fooling them.” - Logan Gilbert after their win against the Red Sox in their game on Sunday. 

"No lead is safe here. We've seen that before. The game can turn in a hurry, so all the insurance runs you can get here are big. (The home run) felt great. I felt like it was flush and a good, true homer. Nice one to watch." - Bryan Reynolds after their win against the Rockies in their game on Sunday.
