The 2019 Major League Baseball trade deadline won't be all about brand-name veterans. Some of the league's best prospects might also change hands ahead of July 31.

We've pointed to eight specific young talents who are worth keeping an eye on as potential trade chips in blockbuster deals. In some cases, this is strictly speculative. Others, however, have already appeared in trade rumors either in the past or more recently.

Using MLB.com's rankings, we'll proceed in order from the lowest- to the highest-ranked prospect.

Brice Turang, SS, Milwaukee Brewers

MLB.com Rank: 92

Although they're still neck-and-neck with the Chicago Cubs in the race for first place in the National League Central, the Milwaukee Brewers have gone just 10-10 in June.

The Brewers' slide is happening largely because their insistence on carrying a low-risk starting rotation is finally backfiring. Their starters have an MLB-worst 6.59 ERA for the month.

If the Brewers are going to seek a substantial fix for this problem on the trade market, they might have to ready themselves to part with 19-year-old shortstop Brice Turang.

Milwaukee drafted Turang out of Santiago High School with the No. 21 overall pick just last year. He's since demonstrated an outstanding hit tool with a .291 average and .395 on-base percentage at the low levels of the minors. He's also a plus runner with the goods to stick at shortstop.

There are questions about Turang's power potential, however, and it'll be several more years before he's ready for the majors anyway. He's therefore far more expendable than Milwaukee's top prospect, 22-year-old infielder Keston Hiura.

Dylan Carlson, OF, St. Louis Cardinals

MLB.com Rank: 88

Elsewhere in the NL Central, the St. Louis Cardinals' own much-maligned starting rotation has turned a corner with a 3.42 ERA in June. 

Yet the Cardinals must be careful about concluding that their rotation's struggles (e.g., with a 4.48 ERA) through the first two months of 2019 are a thing of the past. Their rotation might not necessarily need depth, but Miles Mikolas' regression does point to a need for a reliable ace.

As long as the NL Central lead remains reasonably in sight, this is where the Cardinals might be comfortable trading Dylan Carlson.

The 20-year-old outfielder isn't as well regarded as third baseman Nolan Gorman, but his stock is rising by way of an offensive breakout for Double-A Springfield. Through 70 games, he's slashing .280/.363/.493 with 31 extra-base hits. He also boasts an arm that's racked up 32 assists in four seasons.

But since Carlson is at best an average runner, he profiles more as a corner outfielder than a center fielder. He's looking up at a somewhat crowded depth chart at those spots, so the Cardinals may conclude that he works better as a trade chip than as a long-term building block.

Dustin May, RHP, Los Angeles Dodgers

MLB.com Rank: 51

It's looking like the Los Angeles Dodgers will end up winning their seventh straight NL West title. But after losing the World Series in 2017 and 2018, they're aware that they have unfinished business in October.

Hence president of baseball operations Andrew Friedman's approach to the trade deadline. According to Bill Plunkett of the Orange County Register, his goal is to find "impact players."

The last time the Dodgers pursued such a player on the trade market, the Miami Marlins were asking for two of catcher Keibert Ruiz, infielder Gavin Lux and righty Dustin May for J.T. Realmuto, according to MLB Network's Jon Heyman.

The Dodgers may still hesitate to move any of the three, but it's a safe guess that May is the most available of them. He doesn't loom large in the team's crowd of pitchers, and the disconnect between his great stuff (e.g., his fastball, curveball and cutter) and good-not-great results in the minors allows for some doubt.

In short, the 21-year-old may be just the guy to move for a replacement for injured starter Rich Hill, or perhaps for a much-needed late-inning reliever to help out veteran closer Kenley Jansen.
