BOSTON (Interstat) — Dylan Cease tossed a one-hit shutout with 12 strikeouts, and the Toronto Blue Jays erupted for five runs in the third inning Saturday afternoon, rolling past the Boston Red Sox 6-0 at Fenway Park.

The victory evened the three-game series at one apiece after Boston won the opener 6-4 on Friday. Toronto improved to 48-57, while Boston fell to 53-50 before a crowd of 36,902 in a game that lasted 2 hours, 25 minutes.

Cease was dominant from the outset, retiring the first 12 batters he faced and allowing only a sixth-inning double by Andruw Monasterio. He walked two, hit no batters and threw 108 pitches in his first complete game of the season. The right-hander, who improved to 7-5, struck out at least two batters in six of the nine innings and fanned the side in the eighth. His performance came five days after a loss to Tampa Bay in which he allowed three earned runs over six innings.

Boston starter Sonny Gray had no such luck. The right-hander, who entered with a 12-1 record and a major-league-leading 2.01 ERA, was knocked around for five runs on 10 hits over five innings. He struck out three and walked one, suffering his second loss of the season. Gray had allowed two or fewer earned runs in 14 of his previous 17 starts.

The decisive rally came in the third inning. After Gray retired the first two batters of the frame, Nathan Lukes doubled to left field. Vladimir Guerrero Jr. singled to left, scoring Lukes for the game’s first run. Kazuma Okamoto followed with a single to put runners at first and second. George Springer then launched a three-run home run to left field, his 11th of the season, clearing the bases and giving Toronto a 4-0 lead. Daulton Varsho singled, and Ernie Clement doubled to left, plating Varsho to make it 5-0.

Toronto added an insurance run in the ninth inning. Andrés Giménez led off with a single, advanced to third on Lukes’ second double of the game and scored on Guerrero’s ground-ball single through the right side that deflected off Boston reliever Alec Gamboa. Gamboa pitched four innings of relief, allowing one earned run on five hits with six strikeouts.

Springer finished 2 for 5 with a home run and three runs batted in. Clement was 3 for 4 with an RBI and a double. Guerrero went 3 for 4 with two RBIs. Lukes had two hits, including two doubles, and Varsho added two hits. The Blue Jays collected 15 hits in all.

Boston, meanwhile, managed only one hit: Monasterio’s double to left field in the sixth inning. The Red Sox put only two runners in scoring position all night. Caleb Durbin walked in the fifth and Willson Contreras walked in the seventh, but Contreras was caught stealing second to end that inning. Boston struck out 12 times, with Cease fanning nine of the 12 and relievers adding three more.

For Boston, center fielder Ceddanne Rafaela went 0 for 4 with two strikeouts, right fielder Wilyer Abreu was 0 for 4 with two strikeouts and left fielder Jarren Duran went 0 for 3 with a strikeout. Monasterio was the lone Red Sox batter to reach base safely on a hit, finishing 1 for 3.

The game was a stark contrast to the previous afternoon, when Boston’s offense scored six runs on 11 hits. Toronto’s win snapped a three-game losing streak and was its first road victory since July 10 at San Diego. The Blue Jays had dropped four of their previous five games entering the weekend.

Boston had won seven of its previous nine games before Saturday’s loss. The Red Sox had averaged more than six runs per game over that stretch.

The series concludes Sunday afternoon at Fenway Park. Toronto then travels to Washington for a three-game set beginning Monday, while Boston heads to for a four-game series starting Monday.

Interstat’s game simulator had projected a final score of Boston 7, Toronto 3. Interstat’s ELO system gave Boston a 58.30 percent probability to win. Toronto had been installed as a pregame favorite with a spread of minus-1.5. The total score of six runs went over the over-under line of 7.5.
