SAN FRANCISCO (AP) — Brandon Barnes hit a two-run, inside-the-park home run in the ninth inning and the Colorado Rockies rallied for the second straight day to stun the San Francisco Giants 5-4 on Saturday.

Charlie Blackmon singled with two outs off Giants closer Sergio Romo (3-3) before Barnes lined a hit to center field. San Francisco’s Angel Pagan misplayed the ball and it skipped to the fence as Blackmon and Barnes raced around the bases.

Barnes, who had a walkoff triple to beat the Dodgers on June 7, had flown out to center in three consecutive at-bats before helping Colorado extend its winning streak to four games.

It’s the second consecutive blown save and fourth this season for Romo, who gave up five runs in the ninth inning of Friday’s 7-4 loss to Colorado.
