While Nick Castellanos progresses to ground balls at third base in his rehab from a fractured left hand, Erick Aybar gets the start at third base against Kevin Gausman, who takes the mound with a 19-inning scoreless streak and a 4-0 record with a 1.40 ERA over his last four starts. Michael Fulmer, whose scoreless streak of 33 1/3 innings in May and June remains the longest in the Majors this year, is 0-3 with a 6.48 ERA in three starts since he shut out the Rangers last month at Texas.
