For now, the Mariners are securing the third and final American League Wild Card with their 45-41 record. Before resting on Thursday, they earned their most recent victory on Wednesday against the Royals in Seattle, a typical victory featuring elite pitching, little hitting, but clutch play at the right time. Specifically, they limited the Royals to just six hits. Mariners starter Gilbert pitched 4.2 innings, striking out seven. They then brought in the following pitchers from the bullpen: Gilbert, Speier, Vargas, who earned the W, Brash, and Muñoz, who earned his 19th save. Combined, they managed to pitch 4.1 innings of just one hit per game, striking out seven Royals.

Now, the Mariners rest while awaiting the visit of the Pirates. Although Pittsburgh comes into this game with a 38-50 record, it does so after going undefeated in six straight wins at PNC Park. This came as a surprise to betting sites, as the Pirates have been underdogs in four of those six games.

Our Pittsburgh Pirates vs Seattle Mariners Prediction

Bailey Falter had a short outing of just one inning and two outs in the last game against the Mets due to bad weather, and when the game resumed, his manager didn't want to put him in the game. In 87 innings this season, Falter has a 3.62 ERA. The Mariners will respond with Luis Castillo, seeking his fifth W of the season. He has similar numbers to Falter, albeit with a worse record but a better strikeout rate. Arozarena and Julio Rodríguez hit key home runs for the Mariners on Wednesday. Our prediction for Mariners vs Pirates is: Mariners -1.5.

Prediction:

 

Mariners -1.5.
