Kirk went 2-for-3 with a double and a two-run home run in Sunday's Grapefruit League game against the Pirates.
Getting the start at DH and hitting fourth, Kirk lifted a Dillon Peters offering over the fence in the left-field corner in the first inning. It was the first homer of the spring for the 23-year-old, giving Kirk an early edge over Danny Jansen in the competition for the Blue Jays' starting catcher job.
