Arizona Diamondbacks right-hander Humberto Mejia will start Monday's game against the Pittsburgh Pirates, according to Zach Buchanan of The Athletic. He will be recalled from Triple-A and make his first appearance of the season. A corresponding move will be made afterward. Mejia has just 10 career MLB innings under his belt, posting a 5.40 ERA, and hasn't had great success in the minors this season. Across 86.2 innings, he's pitched to a 5.30 ERA with 91 strikeouts and 29 walks. Mejia is a big question mark, and fantasy managers can keep Mejia on the waiver wire. He should collect enough strikeouts, but his ability to keep runs off the board is suspicious.
