St. Louis Cardinals acquire Paul Goldschmidt from Arizona Diamondbacks in four-player trade

Paul Goldschmidt

The St. Louis Cardinals finished three games out of a wild-card spot and seven games back of the National League Central Division lead in 2018.

How should they make up that difference? Trading for the most complete first baseman in baseball is one way to start.

The Cardinals on Wednesday acquired Paul Goldschmidt from the Arizona Diamondbacks in exchange for pitcher Luke Weaver, catcher Carson Kelly and infielder Andy Young.

I like this move for St. Louis, especially because they did not give up any of their elite prospects, and none of the players they sent to the Diamondbacks figured prominently in their 2019 plans.

Now, Goldschmidt only has one year remaining on his contract, so it's possible this is a one-year rental. But, what a rental it is. Goldschmidt has hit 33 or more home runs in three of the past four seasons, and he has driven in 110 or more runs in three of the past six seasons. His OPS has been .900 or better in five of his six full seasons in MLB, and it was .899 in the one season that it wasn't.

Since his first full season in 2012, Goldschmidt has posted a .400 on-base percentage and .534 slugging percentage, good for a .934 OPS. This is a topnotch middle-of-the-order run producer.

And, oh yeah, he's a three-time Gold Glove winner at first base. The Cardinals now have a much stronger defensive infield with Goldschmidt and second baseman Kolten Wong on the right side. This trade will move Matt Carpenter back to third base, and while I'm not a huge fan of Carpenter at third and Paul DeJong at shortstop -- at least from a defensive perspective --  St. Louis already is better than it was last season.

Can the Cardinals sign Goldschmidt, 32, beyond this year? It won't be easy, although they've traded for and then signed players to long-term deals in the past -- think Scott Rolen, Jim Edmonds and Matt Holliday. St. Louis tried a similar strategy with Jason Heyward, although it didn't work. Heyward entered free agency and eventually signed with the Cubs. Although Heyward now wears a Cubs World Series ring, perhaps the Cardinals don't regret seeing Heyward walk -- he's mostly struggled with the bat in three years in Chicago.

But I digress. I'm a little bit surprised the Diamondbacks didn't get any star power for Goldschmidt. What they did get is, well, guys who are potential pieces to the puzzle.

Weaver, 25, struggled to a 7-11 record and a 4.95 ERA in his first full season with the Cardinals. He likely wouldn't have a spot in the St. Louis rotation for 2019, but he will have an opportunity in Arizona -- especially with Patrick Corbin now in Washington.

Kelly, 24, hasn't had much playing time in St. Louis -- 63 games over three seasons -- and his .154 career average in the major leagues fails to impress in a small sample size. He wasn't going to take Yadier Molina's job with the Cardinals, but should get a longer look in Arizona.

Young, 24, projects as a utility guy, although second base is his best position. He hit .289 at two levels in 2018, finishing the year at Double-A Springfield, where he hit .319 in 35 games.

It's possible that a couple of these guys will help Arizona, but I don't see a future All-Star in the group. St. Louis did well in this trade.

Now, can the Cardinals add the bullpen piece they need to become serious challengers to the Milwaukee Brewers and Cubs? How about Zach Britton or Andrew Miller?
