Segura had three of Seattle's five hits.
It was a rags-to-riches story for the Toronto offence that could do very little after the fourth inning when a Teoscar Hernandez home run cut a 2-0 Seattle lead in half.
Paxton, a six-foot-four left-hander from Ladner, B.C., got two quick strikes before reeling back for a 99-mile-per-hour fastball. The right-handed Leake is 3-3 with a 6.28 ERA and 26 strikeouts.
A national stage in a nation away, Paxton pitched his finest performance in his home country. Through eight starts, Paxton has a sub-4 ERA and now leads the Major League Baseball in strikeouts per game. Urshela, who has played all four infield positions, provides defensive versatility for the Blue Jays, who have shortstops Aledmys Diaz (left ankle) and Troy Tulowitzki (right ankle) on the disabled list, and recently demoted struggling second baseman Devon Travis to Triple-A.
Donaldson hit the ball hard to third baseman Kyle Seager, who collected it and fired to first for the final out.
The roof at Rogers Centre was rolled open for the first time this season under slightly overcast skies over downtown Toronto where the game-time temperature was a sweater-inducing 17 Celsius.
Leake will also be making his eighth start of the season. Instead, with his pitch count at 105, he was finished for the night and then watched his bullpen blow a 2-0 lead. Happ took the loss in his last start, which came Friday on the road against Tampa Bay. In his last four starts, he has allowed 20 runs and 32 hits over 20 2/3 innings. He also had two DL stints, however, and made 24 starts, though that was a career high.
Toronto's bats have fallen silent in the last few games, none moreso than the opener of the set.
Paxton became just the second Canadian to throw a no-hitter, joining Dick Fowler, who threw one for the Philadelphia Athletics way back in 1945.
This season, he is once again proving that if he can stay healthy, he can be our next Hernandez. Look for Seattle to maintain their momentum and take this one to earn the series victory.
Paxton said he realized he had a no-hitter going in the sixth inning, but didn't think much about it. Of course, the numbers don't support how they've gotten there as the Mariners entered Wednesday's game actually being outscored by two runs this season.
Mariners hitters have slashed.255/.322/.425 on their way to 4.5 runs scored per game in 2018, including 5.2 runs per game over the team's last 10 games and 3.6 per game over the team's last five outings (2-3 SU). Martin didn't even break stride as he jogged to the Blue Jays dugout. Toronto can't expect to outscore teams every night: the rotation has to step up and contribute. That generated a Game Score of minus-1 under the James method.
Toronto starter Jaime Garcia pitched well, but continued his trend of not going past the six inning.
