Ondrusek, 31, hasn’t appeared in the big leagues — or, indeed, in North America — since 2014. But he has been pitching quite well in Japan for the Yakult Swallows. Over his 99 2/3 frames on the year in Japan’s NPB, Ondrusek has pitched to a 2.17 ERA with 8.2 K/9 against 3.0 BB/9.

Ondrusek previously enjoyed a solid, if uneven, run with the Reds from 2010 through 2014. He ran up a 3.34 ERA over his first two full seasons in the majors, then dropped off to a 4.69 earned run mark over his final two campaigns. Oddly, though, Ondrusek’s peripherals actually improved quite a bit over 2013-14, as he averaged an improved 8.9 K/9 while dropping his walk rate to 3.0 BB/9.

As for Roe, 29, he’ll enter DFA limbo after throwing 9 2/3 frames for the big league club this season. He has allowed four earned runs in his nine appearances, striking out 11 but also walking seven batters. In 75 1/3 innings over parts of four campaigns, Roe owns a 4.18 ERA with 9.2 K/9 against 4.8 BB/9.
