The Guardians have claimed reliever Matt Krook off waivers from the Athletics and optioned him to Triple-A Columbus, per Tim Stebbins of MLB.com. The southpaw had been designated for assignment by the A’s earlier this week. Cleveland transferred righty Ben Lively to the 60-day injured list to open a 40-man roster spot. Lively recently required Tommy John surgery and will miss the remainder of the season.
Krook, 30, joined the A’s on an offseason minor league deal. The former fourth-rounder pitched well for their top affiliate in Las Vegas, turning in a 3.21 ERA with 21 strikeouts in 14 innings. Krook got grounders on more than 65% of the batted balls he allowed. He’s had a tantalizing combination of whiffs and ground-balls throughout his nine years in the minors. That’s been too often negated by well below-average command, as Krook has walked nearly 15% of his professional opponents.
The A’s selected his contract a couple weeks ago. Krook got into three games, allowing two runs over 3 1/3 frames. The A’s dropped him from the 40-man roster earlier in the week when they acquired Sean Newcomb in a deal with Boston. They tried to sneak Krook back through waivers, but the Guardians jumped in to add the lefty relief depth.
Krook is in his final option year, so the Guardians can keep him in Columbus for the rest of the season if he sticks on the 40-man. He doesn’t throw hard, averaging around 90 MPH on his sinker, but that hasn’t stopped him from racking up plenty of minor league strikeouts. Tim Herrin and long man Kolby Allard are the southpaws in Stephen Vogt’s bullpen. Erik Sabrowski should be back at some point this summer, but he’s been out all year with elbow inflammation.
