The Seattle Mariners completed a four-game sweep of the Houston Astros on Sunday with Edwin Diaz notching a save in each of the games.

Diaz's save on Sunday was his 46th of the season and came in the 10th inning.

"I got a welcomed call from our closer. He said, 'If we got the lead, I'm in the game.' Sometimes you've got to do that. That's kind of how Eddie's wired and how this team is wired," Scott Servais said.

Joe Nathan was the last reliever to have four saves in a single series, accomplishing the feat for the Minnesota Twins in 2004.
