Contreras allowed one hit and walked three while striking out one across scoreless 2.1 innings in Saturday's Grapefruit League game against the Tigers.
Contreras managed to work his way out of trouble, but he walked a batter in all three innings he pitched. Per Jason Mackey of the Pittsburgh Post-Gazette, Contreras also averaged 94.3 mph on his fastball, down around two ticks from the top velocity he's shown in the majors. He's now walked four batters across 4.1 innings of work this spring, which won't help his chances of securing a rotation spot to begin the new campaign.
