Unless there's an injury, there's very little playing time at DH for Kirk. We already have Tellez and Grichik platooning through there.
Kirk should be starting it seems but they won't cut bait with Jansen just yet imo. No one wants to see Kirk split duties at 1 position, especially when you factor in that McGuire has no options left. Jansen should feel the pressure to perform and probably won't get more than a month or two before the Kirk calls getting loud.
