Yankees acquire LHP Francis from A'sYanks deal player to be named for veteran pitcher
Francis, 33, was designated for assignment on July 3 by Oakland, who had acquired him in May after he was DFA'd by the Cincinnati Reds.
With the Reds organization earlier this year, Francis was 4-3 with a 3.33 ERA in eight starts at Triple-A Louisville and made one spot start for the major-league club.
He had been pitching in relief for the Athletics - with his last appearance on July 2 - and was 0-1 with a 6.08 ERA and one save in 13 1/3 innings over nine outings.
For his career, Francis is 70-80 with a 4.95 ERA in 238 appearances (217 starts) with Colorado (2004-10, 2012-13), Kansas City (2011), Cincinnati (2014) and Oakland (2014).
The Yankees made two other roster moves ahead of Friday's series opener in Baltimore, designating RHP Jim Miller for assignment and recalling RHP Matt Daley from Triple-A Scranton/Wilkes-Barre.
