Megill was optioned to Triple-A St. Paul on Sunday, Betsy Helfand of the St. Paul Pioneer Press reports.
Megill made 39 appearances out of the bullpen for Minnesota last season and had a 4.80 ERA, 1.49 WHIP and 49:17 K:BB across 45 innings, but he won't make the Opening Day roster after he allowed eight earned runs in 6.2 frames this spring. The 29-year-old should join the big-league club at some point this season but is likely to be limited to low-leverage work.
