Jenkins was sent down to minor league camp on Wednesday, John Lott of the National Post reports. Jenkins had a horrible spring, giving up eight earned runs and 12 hits including two home runs across 6.2 innings. Jenkins split his time between Triple-A Buffalo and the Blue Jays last season, posting very solid numbers in the majors. He held a 2.56 ERA across 31.2 innings last season with 18 strikeouts in Toronto, but after breaking his hand in batting practice last season, couldn't regain the form he found while with the Blue Jays.
