McCullers (shoulder) said Tuesday that he feels ready to rejoin the Astros' rotation, the Houston Chronicle reports.
Manager A.J. Hinch described it a "big day" for McCullers, who focused on fastball location for most of Tuesday's bullpen session. He was already confident in his curveball and slider after fanning seven over five scoreless innings in a rehab start for Triple-A Fresno on Saturday. The skipper suggested an official announcement is coming Wednesday, but this Saturday in Boston is the presumptive date for McCullers' 2016 debut.
