Colorado Rockies, Tyler Chatwood make a statement against San Francisco on Saturday

Tyler Chatwood made his case on Saturday.

A win on Sunday, and no one will be talking about the Colorado Rockies lackluster offense over the prior two weeks. A win on Sunday, and the conversation will move back to the Rockies being a contender.

On Saturday night, the Rockies rode the wave of momentum to a 10-2 victory over their achilles heel, the San Francisco Giants. The Rockies got a strong performance from Tyler Chatwood on the mound, the same Tyler Chatwood who was impressive against the Dodgers before being sent out for more seasoning.

The small, flame-throwing right-hander did everything he needed to do to keep the pesky Giants at bay, and give his team a chance to score enough runs against Giants starter Tim Lincecum. Chatwood went 5-2/3 innings, giving up one run on seven hits. He walked four and struck out four. The Giants had plenty of base runners, but Chatwood was able to slam the door shut when he needed to.

Maybe the most impressive part of the start for Chatwood was that he wasn't extremely sharp. He didn't have the command that he did in Los Angeles, yet, he still was able to limit the Giants to just one run.

Guest Post: Friday Night Fireworks at Coors Field as Colorado Rockies win a shootout

Jordan Pacheco launched his first career grand slam Friday night.

By Bryan Head (@Bryan5280)

Jordan Pacheco's first career grand slam propelled the Colorado Rockies over the San Francisco Giants at Coors Field on Friday night, ending a 10-game losing streak against their division rivals.

The Rockies fell behind early when former Rockie Marco Scutaro singled off of Jorge De La Rosa, and later scored on a sacrifice fly from Buster Posey.  When the Giants added three more runs in the top of the 2nd inning, it looked like the Rockies were going to once again lose ground in the NL West.

Wilin Rosario gave Rockies fans hope when he led off the Rockies half of the 2nd inning with a single, and later scored on a ground ball from Jordan Pacheco.  The Rockies showed off their speed in the 3rd inning, when Eric Young Jr. led off with an infield single and Dexter Fowler reached on a bunt.  Carlos Gonzalez and Troy Tulowitzki added hard-hit singles to tie the game at 4.

The Rockies blew the game open in the bottom of the 5th when they loaded the bases for Jordan Pacheco.  Pacheco turned on the first pitch that he saw, and launched a no-doubter into the bleachers in left field.  The home run was the first of the season for the 27-year-old, and the first grand slam of his career.

Colorado Rockies blow six run lead, season in a tailspin

Jhoulys Chacin blew a six-run lead for the Rockies.

The old saying in baseball is that every team loses 60 games and every team wins 60 games, it is what the team does in the other 42 games that defines their season.

Of course, which 42 games those defining games are is for anyone to guess.

In a season with 162 games, teams are going to win games that they should have lost, and lose games that they should have won. However, there are often a couple of games throughout a season that a team can point to as season-defining games.

After the Colorado Rockies, losers of 10 straight games to the San Francisco Giants, blew a six run lead that they built on San Francisco Giants starter Matt Cain, it would be hard not to think that the Rockies have officially shifted into non-contender mode.

Colorado Rockies lose lackluster finale in Chicago, need swagger back

The Rockies have a pivotal homestand starting on Thursday.

One step forward, two steps back.

That may be the best way to describe the Colorado Rockies month of May so far. With a chance to win a three-game set in Chicago and salvage a road trip that started off on such a bad note, the Rockies barely showed up on Wednesday night, losing 6-3 to a Cubs team that could lose 100 games for the second consecutive year.

Throughout the past two weeks, the Rockies have had one aspect of their game play well and the other fail. If the pitching is great, the bats don't produce. Rarely has both happened at the same time. However, on Wednesday, neither the offense or the pitching did their part.

Jon Garland, who has proven to be a valuable pickup late in spring training, struggled early. He gave up a leadoff home run to David DeJesus. Despite a few solid middle innings, the dagger was delivered when Garland gave up a two-run blast to opposing pitcher Jeff Samardzija in the 2nd inning, giving the Cubs a 3-1 lead immediately following the Rockies offense tying the game.

Jeff Francis makes his case and Carlos Gonzalez has a career night as Colorado Rockies roll

Carlos Gonzalez had a career night on Tuesday in Chicago.

Listen to the national media and it is clear to them. Carlos Gonzalez is a Coors Field creation.

Ask the Chicago Cubs the same question, and they would quickly disagree. CarGo had a career night on Tuesday night at Wrigley Field, helping the Colorado Rockies route the Cubs 9-4, giving the Rockies a chance to win the series on Wednesday night.

Gonzalez put together his first five-hit night in his brilliant young career. Included in the five hits were two home runs and a double. Both home runs were classic CarGo homers, line drives that had fans in the seats scattering, rather than trying to catch the souvenir.

If Colorado Rockies want to salvage the season, changes need to start now

Juan Nicasio needs some Triple-A seasoning.

It's time.

The Colorado Rockies must start making moves to salvage a season that started with so much promise. It may seem early to declare a team in need of wholesale changes when they were expected to finish in the basement of the National League West. The problem is, they have the talent to compete, and they must not swing and miss at the opportunity.

The Rockies got shelled by a terrible Chicago Cubs team on Monday night. Juan Nicasio started on the mound for the Rockies and continued to cause head-scratching among those following this team. With Drew Pomeranz and Tyler Chatwood pitching well in Triple-A, why is Nicasio still on the big league roster?
