The Pirates recalled RHP Isaac Mattson from Triple-A Indianapolis.

Fantasy Impact

Mattson will return to a middle-relief role in the Pirates bullpen.

Isaac Mattson has been sent to Triple-A Indianapolis.

Fantasy Impact

Mattson has pitched exclusively at the big-league level so far this season, putting up a 4.12 ERA, 1.48 WHIP, and 15-10 K/BB ratio across 19 2/3 innings. He will now head to the minors in exchange for prospect hurler Wilber Dotel, as the Pirates try to shore up their bullpen.

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.

Fantasy Impact

Mattson extended his consecutive scoreless inning streak to 13 straight as he has not allowed a run since giving up two in two-thirds of an inning on Opening Day against the Mets. The righthander is tied for the major league lead with 13 appearances and is tied for fifth in the National League with five holds. Mattson owns a sparkling 1.32 ERA in 13.2 innings, but has allowed 18 baserunners, including a so-so 10:6 K:BB ratio. He'll remain a big part of the bullpen, especially bridging the gap to get to closer, Dennis Santana.
