Colorado Rockies fans know the drill: it's not truly May baseball in Denver without a surprise snowstorm shaking things up. The Mile High City woke up to a winter wonderland this morning, with one of the heaviest May snowfalls in recent memory blanketing Coors Field. As a result, today's second game of the series against the New York Mets has been pushed back to a much later start time, giving the groundscrew plenty of work to do.

But if there's one thing Rockies fans can count on, it's the groundscrew rising to the challenge. Social media has been buzzing with videos of the crew battling the heavy, wet snow—the kind that buried parts of Denver in the city's biggest May storm since 2003. As one tweet put it, "We couldn't play baseball without these people."

Once the snow clears, all eyes will be on the mound, where Michael Lorenzen (2-3, 6.09 ERA) takes the hill for Colorado. Lorenzen has been a bit of a rollercoaster this season, making it tough to predict what you'll get from start to start. His last outing against Cincinnati started strong, but a two-run homer in the fifth inning flipped a 2-1 lead into a loss. The good news? His best performance of the year came against these very Mets, when he fired seven innings of one-run ball on just seven hits. The key for Lorenzen will be limiting walks and keeping the ball on the ground—especially at Coors Field, where contact can be dangerous. He's managed two solid home starts since a rough outing in the home opener against Philadelphia.

On the other side, Freddy Peralta (1-3, 3.52 ERA) makes his eighth start for the Mets, and he's been a steady presence in an otherwise rocky rotation. In his last outing, he held Washington to three runs over six innings, and before that, he allowed just two runs on seven hits in 5.2 innings against the Rockies in New York. Peralta's strikeout ability is his superpower, but he's prone to handing out walks—he's issued at least three free passes in a game this season. That could be a factor against a Rockies lineup eager to heat up their bats in the cold weather.

With snow still melting and first pitch delayed, today's game promises to be a test of patience and grit. Will Lorenzen find his groove at home, or will Peralta's strikeout stuff keep Colorado's bats cold? Bundle up, Rockies fans—it's going to be a chilly one at Coors Field.
