Alcala has opted out of his minor-league contract and will become a free agent, Ari Alexander of 7 News Boston reports.
Alcala failed to make the Blue Jays' big-league roster and triggered the opt-out clause in his contract. The 29-year-old will now hit the open market. He appeared in 56 MLB games last season between the Twins, Red Sox and Cardinals, posting a 6.22 ERA, 1.75 WHIP and 61:30 K:BB across 55 innings.
