Kirk hit a two-run double in the first inning, doubled and scored in the fourth, singled and scored in the sixth and hit a sacrifice fly in the seventh.
“Kirkie is obviously getting hot, hopefully at the right time,” Bassitt said.
Bassitt (13-7) allowed three hits in eight innings. He leads the majors with eight starts of at least six shutout innings this season.
“It starts on the mound with Chris, he was awesome,” manager John Schneider said.
Kirk said location was the key to Bassitt’s big start.
“The way he mixed his pitches, he was unbelievable today,” Kirk said through a translator. “He’s always good at that but today he was special.
Jackson finished Toronto’s 13th shutout as the Blue Jays ensured they would not lose further ground in the AL wild card race. Toronto began the day 3 1/2 games out of a playoff position.
“I would say every game is a must-win from here on out,” Bassitt said. “There’s a lot of pressure on us, there’s a lot of pressure on a lot of teams. Overall, it’s just get the job done.”
The Nationals were blanked for the sixth time.
“Bassitt was good,” Washington manager Dave Martinez said. “He mixed it up today. We couldn’t get in a groove, couldn’t get anything going.”
Washington had just two singles and a walk through the first four innings. Rookie Jacob Young hit a two-out double in the fifth but Bassitt promptly picked him off.
Nationals left-hander Patrick Corbin (9-12) lost for the first time in three starts, allowing six runs and 10 hits in six innings.
“Overall, just a tough day for all of us,” Corbin said.
Corbin has allowed 10 or more hits six times this season, more than any other big league pitcher. Cardinals right-hander Miles Mikolas has done it four times.
Kirk hit a two-out, two-run double off the left-field wall in the first. He doubled starting the fourth, advanced on Clement’s single and scored on Espinal’s hit. Cavan Biggio followed with a sacrifice fly.
Toronto (13) matched Seattle and Cleveland for the most shutouts in the AL.
Toronto was 14-13 in August.
Roger Clemens set a Blue Jays single-season record with nine starts of at least six shutout innings in 1997.
DOUBLES IN THREE
Kirk has doubled in three straight games for the first time in his career.
Blue Jays: LHP Hyun Jin Ryu (3-1, 2.25 ERA) is expected to start Friday as the Blue Jays begin a three-game series at Colorado.
