The MLB trade deadline keeps on going and going and going. Now the Seattle Mariners have traded a pair of relievers– Kendal Graveman and Rafael Montero– to the Houston Astros, according to Brian McTaggart of MLB.com. 

The Astros and Mariners engaging in a deal mark a rather strange occurrence of divisional teams moving pieces at the deadline. What makes this more interesting is that now the Astros add two top-notch relievers, as Graveman has been one of the best in the entire MLB this season.

It is a bit surprising from the Mariners' perspective, due to the fact that they are only six games back of the American League West lead and just helped the Astros out by dealing the relievers. However, Jerry Dipoto has stated that they are in buy and sell mode, and they are still searching to add players as they continue their pursuit of a Wild Card spot.

Mitch Haniger had been one name that floated around as a potential trade candidate, but it looks more and more likely that Seattle holds on to him past the MLB trade deadline. For now, the Astros just bolstered their bullpen, and the Mariners might have just hurt their chances of catching them at all.

Nonetheless, Jerry Dipoto is far from done, and surely more moves are in store for the team from the Pacific Northwest.
