Nate Miller - FantasyPros

 Isaac Mattson pitched a perfect eighth inning on Sunday, including a strikeout, for his fifth hold of the season as the Pirates defeated the Rays, 6-3.
David Leisering
Sun, Apr 19th
Junis has yet to allow a run across eight innings this season and has converted a save in each of his last three appearances. The Rangers have been using a closer-by-committee approach, with Junis working his way to the front of that group.
Bruno Mulé
Mon, Apr 13th
  Junis has now earned saves in back-to-back days for Texas, entering Tuesday's ninth inning against Seattle with a one-run lead. He allowed two base hits before recording two fly outs and a groundout to close it out.
Bruno Mulé
Wed, Apr 8th
  Junis recorded his second save of the season Monday against Seattle, retiring the heart of the Mariners' order in a four-pitch ninth inning. He got Cal Raleigh to ground out, hit Julio Rodríguez with a pitch, then induced a game-ending double play from Josh Naylor.
Bruno Mulé
Tue, Apr 7th
  Jakob Junis has signed a one-year contract with the Texas Rangers that also includes a mutual option for 2027. The deal will become official once the Rangers make a corresponding move to clear a space on the 40-man roster.
