Nate Pearson will face a formidable mound opponent Wednesday night when he makes his major league debut against the host Washington Nationals.
The 23-year-old right-hander will oppose right-hander Max Scherzer (0-1, 6.75 ERA).
Pearson, whose fastball can hit 100 mph, is ranked as Toronto's top prospect.
"The sky's the limit with this kid," Blue Jays manager Charlie Montoyo said Tuesday. "I'm looking forward to seeing him pitch, just like everybody else."
Scherzer, a three-time Cy Young Award winner, is 170-90 with a 3.20 ERA in his career. He took the loss Thursday in the season opener against the New York Yankees, allowing four runs, six hits and four walks while striking out 11 in 5 1/3 innings.
