Orioles tab Ubaldo as club's fifth starter

SARASOTA, Fla. -- The Orioles have tabbed Ubaldo Jimenez to be their fifth starter, with the right-hander slated to make his season debut on Saturday in Baltimore.

Jimenez gradually got better this spring, and the O's want to keep him in a rhythm to start the season -- forgoing the opportunity to bring Opening Day starter Chris Tillman back on regular rest instead. Jimenez, who is working with a new, simplified delivery, takes the final rotation spot over Kevin Gausman, who will be in the bullpen to start the season.

Signed to a four-year, $50 million contract last spring, Jimenez went 6-9 with a 4.81 ERA and was taken out of the rotation down the stretch last season. After a rough spring debut, he pitched to a 2.88 ERA -- with all but one start on the road -- in the Grapefruit League.

He will face the Blue Jays in his start.
