Kendry Rojas will miss time with inflammation in his pitching elbow.
The Twins' pitching puzzle got harder to piece together on Thursday.
Twins starter Bailey Ober was placed on the 15-day IL with right elbow inflammation after allowing 12 hits and 7 earned runs in 4.2 innings Saturday against Pittsburgh. Elbow injuries carry structural risk for pitchers with uncertain recovery timelines; Minnesota calls up Triple-A arm Mike Paredes (3.38 ERA, 33 K in 34.2 IP) for his MLB debut.
The Twins' starting rotation was hit with another injury on Sunday morning.
