DENVER (AP) — Alex Guerrero hit a grand slam off reliever Rafael Betancourt with two outs in the top of the ninth, helping the Los Angeles Dodgers rally for a 9-8 win over the Colorado Rockies on Tuesday night and salvage a doubleheader split.

The Rockies beat the Dodgers 6-3 in the opener behind the pitching of Jorge De La Rosa. The game was a makeup of a rainout on May 9.

Guerrero sent a 1-2 fastball from Betancourt (2-2) to the deepest part of Coors Field, just eluding the glove of leaping center fielder Charlie Blackmon. The crowd waited to see if Blackmon had the baseball as he fell to the warning track. He didn’t.

It was Guerrero’s first career grand slam and fourth homer of the day for the Dodgers.
