The Colorado Rockies
Entering play on Thursday, the team with the best record in the National League is the Colorado Rockies.
In 2021, the weakest parts of their team were their offense (third-worst in the NL by OPS+) and their bullpen (26th in ERA). However, in their first five games, they have six players that have played in at least four of those games with an OPS+ of 155 or higher.
For the bullpen, they have the best ERA in the sport at 0.78. The starting rotation is 12th-best in ERA- at 96 as well. Overall, they have a team ERA of 2.54, which is third in baseball.
With their win on Tuesday in Texas, they recorded their second road win in as many opportunities. It took them until May 1 and their 12th road game in 2021 to get to two wins. They also took two of three against the Dodgers at home to open the season, which is the first time they won a series against the Dodgers at home since 2018.
So if the offense and bullpen can be even somewhat close to that pace for the season, they could be a team that sneaks up on some people for playoff contention.
