Shohei Ohtani will make his fourth start on Saturday, Los Angeles Dodgers manager Dave Roberts said Tuesday while the team announced reliever Michael Kopech had become its 12th pitcher on the injured list. Ohtani will again serve as an opener and Justin Wrobleski is expected to follow as a bulk pitcher against Houston. The Japanese two-way star threw 27 pitches over a season-high two scoreless innings last weekend at Kansas City, giving up a hit with one strikeout and one walk.
