An imposing Shohei Ohtani claimed his first win of the MLB season as the Los Angeles Angels defeated the Houston Astros 6-0 on Wednesday.

Ohtani threw 81 pitches on a night where an 85-pitch limit seemed likely, as well as getting two at-bats in a six-run first inning.

The reigning American League MVP pitched perfect into the sixth inning, with a career-best 12 strikeouts, while also getting two hits and two RBIs in the shutout.

With the Astros traditionally providing him trouble, the 27-year-old did not allow a baserunner until Jason Castro hit a single with one out in the sixth.

The Angels moved to 8-5 with the win, leading the Seattle Mariners by a game atop the AL West.

Tapia leads Blue Jays to win over Red Sox

Raimel Tapia hit his maiden home run since joining from the Colorado Rockies, with a two-run slam in a five-run second inning as the Toronto Blue Jays beat the Boston Red Sox 6-1.

Jose Berrios claimed his first win in three starts this season, giving up just one run and eight hits in six innings, with six strikeouts and a solitary walk.

Meanwhile, Nick Pivetta gave up five runs, seven hits and four walks on the way to being pulled before the fifth inning – a second time in as many starts for the Canadian.

Giants ride Rodon to victory

Carlos Rodon broke a franchise record for the San Francisco Giants in their 5-2 win over the New York Mets.

After signing from the Chicago White Sox, Rodon struck out eight over five scoreless innings and moved to 27 over his first three starts, breaking the previous record of 26 set by Cliff Melton in 1937.

While Joc Pederson, Brandon Crawford and Wilmer Flores helped build an early 3-0 lead, Rodon was the star of the show, limiting the National League East-leading Mets to three hits and two walks on 95 pitches.
