Lopez could join the big-league rotation Friday against the Royals, Colleen Kane of the Chicago Tribune reports.
He will start Sunday for Triple-A Charlotte, and if all goes well, it sounds like he will make his next start as a member of the big-league rotation. Lopez has a 3.65 ERA, 1.22 WHIP and 122 strikeouts in 116 innings this year and has allowed two or fewer runs in seven straight starts, striking out at least 10 in three of those outings. He is worth an add in deep mixed leagues and should have already been rostered in AL-only formats.
