The Blue Jays optioned Martinez to Triple-A Buffalo on Thursday.
Martinez missed a few days of spring training after he was hit by a fastball on the hip Monday. He was able to return to action Thursday and log an at-bat. The infielder has been slashing .320/.393/.480 with a home run across 28 plate appearances in Grapefruit League play. At Triple-A Buffalo, the 23-year-old will play every day and wait for his next chance to prove himself in the big leagues.
