Mejia was promoted to Triple-A Sacramento on Friday.
Mejia, who turns 23 on Monday, has been fabulous at Double-A, posting a 1.94 ERA and 58:16 K:BB in 65 innings. He is not only one of the Giants' top prospects, but he is one of the closest to the big leagues, in terms of potentially impactful talent. It's not clear how many innings the Giants have in mind for Mejia in 2016, as he only threw 82.1 frames last year between Double-A and the Arizona Fall League, but he could be an option at the big league level if he hits the ground running at Triple-A.
