Willson Contreras’s two-run homer lifted Red Sox over Braves...

By the end, Tolle’s ERA had actually risen, from 1.99 to 2.05. With the rookie lefthander at 85 pitches, interim manager Chad Tracy turned to Aroldis Chapman for the ninth. Chapman worked around Andruw Monasterio’s two-out throwing error to save the win — barely. He walked consecutive batters to load the bases before getting Ha-Seong Kim to shoot a comebacker off of his leg. Chapman recovered, fielded the ball near the first-base line, and flipped to first for the final out. Tolle became the first Sox pitcher to finish eight innings in 85 pitches or fewer since Aaron Cook in 2012. The team’s only other hurler to do so this century is Derek Lowe, who did it twice. Braves righthander Bryce Elder was efficient and effective throughout but cracked on Contreras’s long ball. He gave up three runs and seven hits across eight innings. The clubs were knotted at the halfway point, having traded lone runs via very different means. The Braves got theirs the easy way, on Drake Baldwin’s home run to lead off the bottom of the first. It was the second game in a row that he went deep off a rookie lefthander in the opening inning, after doing so against Connelly Early on Friday. The Red Sox got theirs in the fourth in a much harder way, on a pair of singles and a fielding error by third baseman Austin Riley, who flubbed a routine double-play grounder. That gifted the Sox a golden scoring opportunity: bases loaded, no outs. It meant that when Masataka Yoshida flied out to left field, it brought in Mickey Gasper from third base instead of ending the inning. Atlanta challenged the call at the plate and seemed to have a case. Replays showed that Gasper’s foot appeared to bounce off the ground and hover above the plate as catcher Sandy León applied the tag. After an extended review, though, the call stood — meaning umpires didn’t have enough evidence to confirm or overturn it. Baldwin struck again in fifth, following Jose Azocar’s two-out double. On Baldwin’s single to left field, third base coach Tommy Watkins challenged Jarren Duran’s arm — and won. Azocar scored easily, though catcher Gasper threw Baldwin out at second. The Red Sox failed to come through after leadoff doubles in the first and seventh frames. Neither Duran nor Ceddanne Rafaela advanced even one base. Duran’s double snapped an 0-for-18 skid.
