CHICAGO - Munetaka Murakami was replaced after experiencing right hamstring tightness during the Chicago White Sox's 4-3 walk-off win over the Detroit Tigers in 10 innings, while the Toronto Blue Jays' Kazuma Okamoto and the Los Angeles Dodgers' Shohei Ohtani both hit home runs Friday.
Murakami, in a joint American League lead with 20 homers, grounded into a force out while beating the double play in the third inning at Rate Field. He was then seen clutching the back of his right leg and exited the game after speaking to his team's staff member on the field.
White Sox skipper Will Venable said after the game that Murakami would likely miss "a couple of weeks."
The 26-year-old first baseman has played in all 57 games so far this year after the former Triple Crown winner in Nippon Professional Baseball was posted by the Yakult Swallows in the offseason.
His fellow MLB rookie Okamoto sparked a 6-5 comeback win for the Blue Jays against the Baltimore Orioles, crushing a first-pitch four-seamer from Trevor Rogers for a two-run shot to get his team on the board in the seventh.
Charles McAdoo also hit a two-run homer off the left-hander in the frame to make it a one-run game and Vladimir Guerrero Jr.'s two-run double in the eighth off Yennier Cano (1-2) completed the turnaround.
"It was good to get a home run, also for me personally. I was able to belt it," said Okamoto, who hit his first homer since May 5 on Wednesday. "Turning the game around late on is something we can build on. I believe we're managing to play games tenaciously."
Two-way superstar Ohtani registered his 10th homer in a 3-for-4 effort as the Dodgers beat the Philadelphia Phillies 4-2, reaching double figures for the sixth straight season as he went deep in back-to-back games.
Ohtani connected on a 1-0 splitter from Zack Wheeler (4-1) and sent it over the right-field fence at Dodger Stadium in the third, getting one of the Dodgers' four solo shots after Freddie Freeman in the first, Max Muncy in the second and Will Smith in the fifth also homered.
Shota Imanaga (4-6) picked up a loss after the Chicago Cubs lefty gave up five runs on five hits, including three home runs, in their 6-5 defeat to the St. Louis Cardinals. Seiya Suzuki went 3-for-4 for the Cubs.
