The Twins have signed left-hander Ian Krol to a minor league contract, according to Nate Rowan, Triple-A Rochester’s director of communications. Krol has already joined Rochester’s roster.
The 28-year-old Krol was previously with the Reds, who inked him to a minors deal over the winter. He threw 25 1/3 innings with their Triple-A affiliate in Louisville this season and managed a subpar 5.33 ERA/4.08 FIP with 9.95 K/9, 4.26 BB/9 and a 41.4 percent groundball rate. Krol has typically prevented runs at a much better clip in Triple-A ball, having combined for a 3.35 ERA with 10.1 K/9 and 4.0 BB/9 across 137 innings.
Of course, the hope for the Twins is that Krol will thrive in the minors and work his way to their bullpen. Krol was a viable major leaguer as recently as 2016, when he pitched to a 3.18 ERA/2.91 FIP with 9.88 K/9, 2.29 BB/9 and a 56 percent grounder rate in 51 innings as part of the Braves’ relief corps. But Krol otherwise hasn’t experienced a ton of big league success. Also a former National, Tiger and Angel, Krol has registered a 4.50 ERA/4.43 FIP with 8.43 K/9, 3.46 BB/9 and a 45.2 percent GB mark in 190 innings at the sport’s top level.
