PITTSBURGH _ A 2-hour, 5-minute rain delay in the top of the fourth inning Tuesday night merely delayed the Cubs' latest misery.
Mike Montgomery surrendered a three-run home run to Adam Frazier with two out in the bottom of the fourth as the Pirates pulled away for a 5-1 win at PNC Park.
Frazier's homer highlighted a 4-for-4 performance that extended his streak of consecutive hits to seven, tying Freddy Sanchez's team record set May 26-27, 2009. Frazier is 9-for-10 in the first two games of this series.
The Cubs (45-41) lost their third consecutive game and have lost 14 of their last 18 road games as they remain one game behind the Brewers in the National League Central.
Kyle Hendricks, activated from the injured list, allowed two runs on four hits in three innings and 55 pitches. Hendricks hadn't pitched since June 14 because of right shoulder inflammation.
After the rain delay, Hendricks was pulled in favor of Dillon Maples, who allowed a walk and a two-out single to pitcher/pinch hitter Steven Brault before Montgomery replaced him.
The Cubs were blanked until Willson Contreras doubled with two out in the ninth to score Kyle Schwarber.
