Dodgers two-way superstar Shohei Ohtani worked two scoreless innings against the Houston Astros in his fourth mound start of the season. He struck out the side in order in the second while pitching on his 31st birthday. Ohtani allowed one hit and threw 31 pitches, 21 for strikes. He fanned Christian Walker, Victor Caratini and Yanier Diaz — all swinging — to conclude his latest outing as an opener as he works his way back from elbow surgery. In his previous start a week earlier, Ohtani threw the fastest pitch of his career at 101.7 mph. On Saturday, he hit triple digits only once — a 100.9 mph fastball that Caratini fouled off.
