With Major League Baseball’s all-star game set for Tuesday and the unofficial first half of the season finishing up Sunday, it’s a good time for fans to take a look at how their favorite teams and players are doing heading into the second half.

Like every other season, we’ve had surprises and disappointments in the first three months of the year. Here are the winners and losers of the first half:

Winners

Houston Astros

On June 20, 2014, Sports Illustrated called the Astros “Your 2017 World Series Champs.”

Houston tanked from 2011 to 2013, never winning more than 56 games in the process.

Former Cardinals executive Jeff Luhnow rebuilt the farm system and they won an average of 85 games the previous two seasons, including a playoff berth last year.

And, right on cue, the Astros are 56-27 and have the best record in the Major Leagues.

They have one of the games’ best lineups, featuring Jose Altuve, Carlos Correa and George Springer.

They have two aces in starting pitchers Dallas Keuchel and Lance McCullers Jr., and they are the favorites to win the World Series this season.

If your team is going to be bad, the Astros showed us that it’s OK to go all-in on a total rebuild.

Max Scherzer

Max Scherzer, St. Louis native and Parkway Central graduate, has made a good case to be considered the best pitcher in the Majors, ahead of the Los Angeles Dodgers’ Clayton Kershaw.

The 32-year-old leads Major Leagues in innings pitched (120 2/3), earned-run average (1.94) and Wins Above Replacement (4.7), and is second in strikeouts (163).

Sunday night he out-dueled Cardinals’ ace Carlos Martinez on national television, giving up two hits and striking out 12 in seven innings.

Matt Holliday

Matt Holliday looked lost more often than not in left field during his eight years in St. Louis, and getting older didn’t help.

Enter the American League and the designated hitter.

Holliday signed with the New York Yankees last offseason and has 15 home runs and 47 RBIs in the first half.

The aging slugger wasn’t getting a ton of looks from teams last winter, but barring a total collapse in the second half, he should be able to sign another 1- or 2-year deal when his contract is up after this season.

There aren’t many 37-year-old position players who can make $10 million or more per season, but Holliday should do just that next year.

Losers

The National League Central

The Chicago Cubs were supposed to dominate again and the Cardinals were supposed to contend for a Wild Card spot.

Instead, both teams have hovered at — or below — the .500 mark while the Milwaukee Brewers sit two games ahead in first place; the same Brewers team that would be 11 games out of first in the National League West.

Conventional wisdom says Milwaukee will fade into obscurity eventually, but nobody else in the division gives us any reason for optimism.

The Cubs’ starting rotation isn’t nearly as good as 2016 and leadoff hitter and apparent star-to-be Kyle Schwarber has spent the last two weeks attempting to fix his swing at AAA-Iowa.

The Cardinals, meanwhile, took four-out-of-six from the Diamondbacks and Nationals last week and were still three games under .500 heading into Monday.
