Colorado scored six times in the eighth to tie the game on rookie Josh Rutledge's grand slam.
In the ninth, Everth Cabrera reached on a one-out infield single against Matt Belisle (3-7). With two outs, Belisle balked Cabrera to second and then intentionally walked Chase Headley to bring up Alonso.
The left-hander lined a ball right at left fielder Andrew Brown, whose throw was slightly late to the plate as Cabrera slid in with the winning run.
Joe Thatcher (1-4), came on to strike out final two batters with runners on first and second in the top of the ninth.
