Shohei Ohtani went deep for the second straight game for the Los Angeles Angels on Monday while the Boston Red Sox's Masataka Yoshida blasted his first MLB home run.
Two-way star Ohtani, batting third as the designated hitter at T-Mobile Park against the Seattle Mariners, broke a 2-2 tie with a two-run homer in the fifth inning during the Angels' 7-3 win.
The World Baseball Classic MVP in March launched his second homer in two days, sending a 1-1 changeup from George Kirby over the center-field wall.
Boston's new acquisition Yoshida, meanwhile, homered in the first inning in the Boston Red Sox's 7-6 loss to the Pittsburgh Pirates.
Batting cleanup in all four games so far this season, Yoshida belted Johan Oviedo's high 1-0 four-seamer for an opposite-field two-run shot over the Green Monster at Fenway Park, tying the game at 3-3.
"I was able to get a good swing and felt I made a good contact," said Yoshida, who set a WBC record of 13 RBIs to help Japan win the tournament for the third time.
Jason Delay broke a 5-5 tie in the fourth with a solo homer and Bryan Reynolds added a shot of his own later in the inning to score the decisive seventh run for the Pirates.
Yoshida, a two-time Pacific League batting champion with 133 home runs over seven seasons, all with the Orix Buffaloes, signed a five-year, $90 million deal with the Red Sox, the biggest deal for a Japanese position player moving to the majors from Nippon Professional Baseball.
