TODAY: Sipp has elected free agency, according to MLB.com's transactions page. Presumably, that means he cleared waivers and refused an outright assignment.
NOVEMBER 20th: The Diamondbacks announced that they have designated Tony Sipp for assignment. The move will allow Arizona to select the contracts of outfielder Ender Inciarte and right-handed pitcher Bo Schultz from Triple-A Reno.
Sipp, 30, pitched to a 4.78 ERA with 10.0 K/9 and 5.3 BB/9 in 56 relief outings last season. Across five big league seasons, four of which were spent in Cleveland, Sipp posted a 3.84 ERA with 9.3 K/9 and 4.6 BB/9. This marks the second time that Sipp has been designated for assignment by Arizona this year. He was DFA'd by the D'Backs and subsequently optioned to Triple-A in August.
