Rojas tossed four scoreless frames in a start against the Athletics in his last appearance over the weekend, but he shifted back to a relief role this week after Connor Prielipp (finger) returned from the injured list to fill the open spot in the rotation. Rojas, a 23-year-old lefty, mopped up after starter Joe Ryan covered the first six innings, and the former trimmed his ERA down to 2.51 for the season. Ryan is expected to be a sought-after commodity ahead of Monday's trade deadline, and if he ends up getting moved, Rojas could be first in line to join the Minnesota rotation.

Rojas made his fourth start of the season as an emergency replacement for Mike Paredes, who was a late scratch due to an oblique injury. Though there was no expectation that Rojas would go very deep after having thrown fewer than 50 pitches in each of his three outings since being recalled from Triple-A on July 9, the left-hander ended up hurling 56 pitches Saturday and lasted four frames, tying his longest big-league start of the campaign. Rojas didn't go long enough to qualify for the victory, but he certainly played a big part in Minnesota's win, limiting the A's to just two baserunners (on a single and a walk) and zero runs. Rojas has plenty of experience as a starter in the minors, and he's a candidate to move into the rotation if Paredes and/or Joe Ryan (arm) needs to miss time.
