Orioles To Select Zac Lowther, Option Isaac Mattson

By TC Zencka | May 8, 2021 at 9:02am CDT

The Orioles optioned Isaac Mattson to Triple-A after Friday night’s game, creating a roster spot for Zac Lowther, per Roch Kubatko of MASNsports.com (via Twitter). Lowther will start Saturday’s ballgame.

Mattson was drafted and raised in the Angels’ farm system, but he made his Major League debut last night for the Orioles. He surrendered one earned run on a walk and a hit in 2/3 of an inning. Mattson wrapped the 2019 season with five innings in Triple-A with the Salt Lake City Bees. He came to Baltimore as one of four pitchers in the Dylan Bundy trade.

Lowther will make his second appearance of the season on Saturday, having previously tossed a scoreless inning against the A’s on April 25th. Fangraphs has him as Baltimore’s 18th-ranked prospect coming into the season. Elite extension helps buoy a fairly standard three-pitch mix for the former second round pick. Lowther posted a 2.55 ERA across 148 innings in Double-A back in 2019.

    Lowther just needs to pitch. He is going to be better then his prospect rankings. He just knows how to pitch.

    Lowther is already on the 40-Man and was called up earlier this year. This article needs proofreading.
