The Giants and the Colorado Rockies had to wait out a long rain delay on Thursday, but the rain just did not stop in time for the game to continue, as the game was halted in the bottom of the sixth due to the wet weather.

The teams were deadlocked at 2-2, and there was no immediate date to finish the game.

Michael Cuddyer started the scoring in the second inning, as his infield single scored Willy Rosario. However, the Giants roared right back in the fourth with two runs to take the lead, as Hunter Pence launched a solo homer over the right-field wall while Pablo Sandoval added a run-scoring double to give the Giants a 2-1 lead.

Colorado tied the game in the fifth inning, as Rosario hit into a double play while Nick Arenado scored.

Meanwhile, the Giants got the diagnoses back for both of the pitchers who suffered hamstring injuries in Wednesday’s game.

Matt Cain suffered a Grade 1 strain – considered a mild strain -and is not expected to miss much time. However, reliever Santiago Casilla was diagnosed with a Grade 2 – or medium – strain and is expected to miss about four weeks due to the injury.

Casilla was injured running out a ground ball in the ninth inning of Wednesday’s 5-1 win over the Rockies. He was the second reliever to be injured on the basepaths this year, as David Huff strained his left quadriceps while getting his first major-league hit April 21 and ended up missing 18 games.

The Giants come back home to start a three-game series at AT&T Park on Friday against the Minnesota Twins. Tim Lincecum (3-3, 4.74 ERA) will take the hill for the Giants, facing Minnesota righty Kyle Gibson (4-3, 4.20 ERA).

The Twins are currently two games over .500, a position that they have not been in since they won the American League Central title four years ago.
