Yacabonis will start Wednesday's game against the Blue Jays, Rich Dubroff of BaltimoreBaseball.com reports.
Yacabonis will make his first start at the big-league level since late August when he allowed six earned runs in a dreadful performance versus the Yankees. Since being recalled from Triple-A Norfolk earlier this month, he's logged a 4.82 ERA and 1.07 WHIP across three relief appearances.
