SEATTLE — Blue Jays first baseman Vladimir Guerrero Jr. had a throw bust through the webbing of his glove and the Seattle Mariners took advantage for their eighth straight win, beating Toronto 6-5 Sunday on two home runs by Carlos Santana.
A day after Santana hit a two-run homer in the seventh inning for a 2-1 win, he connected for a go-ahead, two-run drive in the eighth. The Mariners are 16-3 for their best 19-game stretch since 2003.
Blue Jays starter Max Castillo was pulled in the fifth with a 4-1 lead after giving up a pair of one-out singles, and reliever David Phelps walked Justin Upton to load the bases.
Sam Haggerty then grounded back to Phelps, who threw home to start what appeared to be an easy inning-ending double play. But catcher Gabriel Moreno’s throw broke through Guerrero’s first baseman’s mitt, allowing a run to score.
Guerrero kept looking in amazement as his glove while Phelps, who had begun to twirl off the mound in celebration, suddenly stopped. Julio Rodriguez followed with an RBI single that cut Toronto’s lead to 4-3.
Bo Bichette had a homer, two singles and drove in three runs for the Blue Jays, who were swept in the four-game series and have lost nine of their last 10.
George Springer homered on the first pitch of the game for the Blue Jays, his 17th home run of the season and his 51st career leadoff homer. Raimel Tapia also homered for Toronto.
Santana, acquired from Kansas City in late June, hit a leadoff homer in the second.
Moreno dropped a popup by J.P. Crawford to begin the Seattle eighth. Santana connected off Adam Cimber (8-3) for his seventh home run this season, three for the Mariners.
The Mariners tied it at 4 on Cal Raleigh’s sacrifice fly in the sixth. Bitchette homered in the seventh.
Seattle starter Logan Gilbert allowed four runs on nine hits, both matching his season highs, in six innings.
Matt Festa (1-0) pitched a perfect eighth for the win and Paul Sewald picked up his 10th save.
On Saturday, the Mariners optioned rookie starter George Kirby to Triple-A Tacoma to reduce his workload. Seattle manager Scott Servais said he expects Kirby to make one start of two or three innings at Tacoma and return to the Mariners’ rotation after the All-Star break. In his place on Wednesday at Washington, Seattle may have a bullpen day or start long reliever Tommy Milone, Servais said. Marco Gonzales will start Thursday in Texas.
Mariners RHP Chris Flexen (5-8, 4.00 ERA) will open Seattle’s two-game series at Washington on Tuesday. Flexen has won his last three starts.
