PITTSBURGH (AP) -- The Pirates trailed by one run when rain stopped play for more than two hours in the bottom of the seventh inning. After play resumed, Cleveland added to its lead in the top of the eighth and snapped Pittsburgh's three-game win streak.
Pirates manager Clint Hurdle refused to blame the delay for affecting his team's play.
"We don't get caught up in all that external stuff," Hurdle said. "We've got a game to play. If it rains, you come off the field and wait until it's time to go back on."
Michael Bourn drove in three runs, including the key two-run single in the eighth, and Trevor Bauer pitched effectively into the seventh inning as the Indians beat the Pirates 5-2 on a rainy Friday night in a game that stretched past midnight.
Andrew McCutchen's two-run home run in the bottom of the fourth, his 10th, pulled the Pirates to 3-2. They got no closer in a game that was delayed by rain for 2:08 in the seventh inning and ended at 12:26 a.m.
The Pirates were coming off a three-game sweep at Detroit in which they had 49 hits, including 17 for extra bases.
Charlie Morton (6-2) gave up three runs and four hits in six innings, with three walks and three strikeouts. He had pitched a combined 12 scoreless innings in his two previous interleague starts.
"I felt a little out of whack with my mechanics but I pretty much always feel out of whack," Morton said.
Brandon Moss opened the scoring with a two-run homer, his 14th, in the second and Bourn had an RBI double in the fourth inning to put Cleveland ahead 3-0.
"We're going to play meaningful games in September, we're not going to be counting down the days (until the end of the season)," Bourn said. "I don't care how much money you make, how long you've been playing, it's not fun when the games don't count in September."
Bourn and Gomes each had two hits as the Indians ran their winning streak to five games.
Bauer (7-5) allowed two runs and three hits in 6 1/3 innings after going 1-3 with a 7.40 ERA in his previous four starts. He improved to 5-2 in eight road starts this season while striking out three and walking one.
Cody Allen pitched a perfect ninth to complete the three-hitter and get his 16th save.
Pirates: RHP Jameson Taillon, the Pirates' first-round draft pick in 2010, will undergo hernia surgery next week and will miss two months. He was injured last month during an extended spring training start while rehabbing from Tommy John elbow ligament replacement surgery that caused him to miss last season. He finished last season at Triple-A Indianapolis.
VOLSTAD TO INDY
RHP Chris Volstad accepted an outright assignment to Indianapolis by the Pirates as he cleared waivers after being designated for assignment. He made one relief appearance, pitching two scoreless innings.
Pirates: LHP Jeff Locke (4-4, 4.55) is 5-1 with a 2.84 ERA in eight career interleague starts.
Indians: RHP Cody Anderson (1-0, 0.57 ERA) will make his third major league start, and first since getting his first career win Monday against the Rays, when he took a perfect game into the seventh inning.
