SAN FRANCISCO -- The top of the first inning really couldn't have gone much worse for the Giants on Thursday night.
After Brandon Crawford's nightly highlight play kicked things off, the wheels came off for the Giants and starter Scott Kazmir was removed with an injury.
After the Giants walked off on the Arizona Diamondbacks, manager Gabe Kapler said Kazmir suffered a right hamstring strain while covering first on a second straight botched defensive play by the Giants, one that gave the Diamondbacks a 2-0 lead.
Kazmir will undergo an MRI on Friday.
The first out of the night came on a nifty play by Crawford up the middle, but Kazmir walked the next two batters and didn't have much command against cleanup hitter Carson Kelly, either. His single to center got the Diamondbacks on the board.
Christian Walker followed with a bloop to center that should have been the second out, but Austin Slater didn't call off Donovan Solano and the ball dropped between them. Pavin Smith hit a grounder to the right side and beat it out as Kazmir got hurt right as he hit the bag.
Kazmir was removed immediately and replaced by Kervin Castro, who walked in a third run but struck out Madison Bumgarner to get out of the jam.
