Swanson posted his fifth career four-hit game before departing in the sixth with tightness on his left side. He is batting .400 (16 for 40) in his first 10 games with his new team.
Swanson said he cramped up after getting up at 4 a.m. and spending the day with his wife, U.S. soccer star Mallory Swanson, who underwent surgery on Tuesday for a knee injury after she got hurt Saturday in a game against Ireland.
“It’s been a long few days and today was an exceptionally long day as well,” Swanson said. “Realistically, I just felt like my body’s just kind of like done. The night was over for me, pretty simple.”
Eugenio Suárez and Jarred Kelenic homered for Seattle in its third consecutive loss. Suárez drove in three runs, and Ty France finished with three hits and two RBI.
The wind was blowing out at Wrigley Field on a warm night.
“We knew that conditions were going to be very favorable for the offensive side,” Seattle manager Scott Servais said. “I thought early in the game our at-bats were great.
“We jumped all over their starter. We were in a really good spot.”
The Mariners made the most of errors by Swanson and Mancini in the second, scoring five unearned runs on their way to a 7-0 lead. It was each player’s first error with Chicago.
But the Cubs responded in the third, sending 13 men to the plate. Mancini hit a two-run shot and Eric Hosmer added an RBI single. Velázquez then hit a drive to left-center against Chris Flexen, making it 8-7 and sending the crowd of 30,081 into a frenzy.
“It was so pure,” Swanson said. “The energy was just amazing. As soon as Nellie hit that ball, I hadn’t really felt too many things like than in my career.”
Flexen (0-2), making his second start in place of the injured Robbie Ray, departed after Velázquez’s homer. He was tagged for 10 hits and walked two.
Chicago starter Hayden Wesneski recorded just four outs. He was charged with seven runs, two earned, and five hits.
Michael Rucker (1-0) pitched 2 2/3 innings of one-run ball for the win.
Kelenic connected for a solo shot in the fourth, but Swanson and Mancini each hit an RBI single in the fifth and the Cubs tacked on three more in the sixth.
