DETROIT (Kyodo) -- Yusei Kikuchi allowed five runs and exited early with his team trailing on Tuesday, but Kyle Seager led an offensive blast with three home runs and six RBIs that helped lift the Seattle Mariners to an 11-6 win over the Detroit Tigers.
The Japanese starter yielded nine hits in 3-1/3 innings at Comerica Park and blew the Mariners' two-run lead after giving up long balls to John Hicks and Jake Rogers in the fourth.
"The balls were responsive, they just found a sweet spot where it mattered," Kikuchi said. "My change-up had good movement, but not my slider. My slider is my go-to pitch but it was a little difficult today."
A second pair of back-to-back homers from Seager and Tom Murphy off Tigers starter Matthew Boyd resulted in four runs in the sixth and put the Mariners ahead for good.
With two outs in the ninth, Seager recorded his third homer of the game after his blast to the warning track in left-center bounced off the glove of Niko Goodrum in an outfield collision. Seager and Murphy also crushed consecutive solo shots in the fourth.
Mariners rookie Zac Grotz (1-0) took over for Kikuchi and limited the Tigers to a run through the fifth to earn his first major league win in his third appearance. Boyd (6-9) was tagged for seven runs and took the loss.
Kikuchi, who is 4-8 with a 5.56 ERA in 25 starts in his rookie season, has not won a decision since June 23 against the Baltimore Orioles.
At Angel Stadium, Shohei Ohtani drove in two runs and scored twice, but the Los Angeles Angels' bullpen squandered the hosts' lead on the way to 10-7 loss to the Pittsburgh Pirates.
Ohtani put the Angels on board with an RBI double in the first and came around to make it 3-0 before the frame ended. The Japanese designated hitter also belted a run-scoring triple in the second.
The Pirates turned it around with a four-run rally against Los Angeles reliever Taylor Cole (2-4) in the fifth. The Angels bullpen gave up a combined seven runs as the club's offense fizzled out.
"The lineup just couldn't string anything together, that's why we lost," Ohtani said.
In the ninth, Ohtani reached on a force out, stole second for his 10th stolen base of the season and crossed the plate on Justin Upton's two-run single before a game-ending double play squashed the effort.
"It's not a bad thing to aim to be aggressive and go for a base," Ohtani said of reaching double digits in stolen bases for the second straight season. "I want to pile them up one by one."
