Buy or Sell: Time to get bullish on Dozier

Here are two players you should buy with their value steadily on the rise, and two players you should sell before their stocks dip.

Buy

2B Brian Dozier, Minnesota Twins

Dozier was ice-cold to start the season, hitting just .199 from Opening Day to May 24. Though always known as a low-average hitter, at least he could be counted on for production in runs, homers and steals, but those categories fell off as well.

Though the Twins are now well outside of the pennant race, at least Dozier has awoken at the plate. Since homering on May 25, he has hit .318 with a .398 OBP, four homers, 17 runs, 15 RBIs and four steals in just 28 games. That's the sort of production that Dozier's backers have come to expect.

While an OBP approaching .400 shouldn't be counted on, the general success that Dozier has found should carry into the dog days of summer. The day one lineup in Minnesota was stacked with unproven, young talent. With some in-season tinkering, the team has found some consistency as a whole and looks to be more like a below-average than historically awful team from here on out.

SP Drew Pomeranz, San Diego Padres

Pomeranz is one of just seven qualified pitchers with a K/9 above 10.5. The other six are: Jose Fernandez, Max Scherzer, Stephen Strasburg, Clayton Kershaw, Noah Syndergaard and Chris Archer. That is some pretty elite company.

While Pomeranz doesn't have the polish of the league's aces, he does have the per-inning production on a strikeout basis. That will prove highly valuable if he can make the jump to a heavier workload this season. He currently stands just five innings behind last year's innings total, but pitched nearly 150 innings across three levels in 2012. At 27, it's time to turn up the volume.

The Padres aren't going to be league leaders on offense, but like the Twins, their stock as a whole is on the rise. That bodes for the run support that Pomeranz will receive. He should be able to net five to eight more wins for the rest of season.

You can afford to gamble on finer points of his game -- curtailing his walk-rate, keeping his home rate low, avoiding hard contact -- because his strikeout rates can sustain his value for now.

Sell

OF Adam Duvall, Cincinnati Reds

Duvall has had 333 plate appearances with the Reds since the start of the 2015 season. In those trips to the dish, he has hit 26 long balls. While the probable All-Star is currently tied for the major league lead in home runs with the likes of established sluggers Nolan Arenado, Todd Frazier and Mark Trumbo, the good times are unlikely to last.

There are two stats that reek of unsustainability. The first is his 46.9 percent fly ball rate this season, ranked seventh in the majors. While it's possible to survive with that extreme batted-ball likelihood, it's hard to bust out of a bad streak when you can't make consistent line drive contact. It helps keep the defense honest.

The second thing that jumps out is Duvall's preposterous homer-to-FB rate, 25.6 percent. His fly balls are literally leaving the park twice as often as the average major-leaguer who homers on 12.6 percent of their FBs. Those numbers make Duvall look like Giancarlo Stanton.

Once pitchers find out which pitches can expose Duvall's swing, the power numbers will dry right up. He hasn't shown an ability to draw walks during his time in the majors and without that tool in his arsenal, all of those booming fly ball balls are going to become poor-contact grounders and pop-flies. Sell your Duvall stock now; it's never going to be higher.

1B Freddie Freeman, Atlanta Braves

Freeman, along with SP Julio Teheran, have been the lone bright spots in what has been a predictably ugly season in Atlanta. And if you're not playing in a keeper league, it's time to consider trading the former.

With a slash line of .275/.342/.476 on the year, Freeman is having another typically refined year at the plate. The issue here is the roster he's playing on. Freeman has been worth 10.0 offensive runs above average so far this year; the closest Brave is Gordon Beckham, worth just 3.5 offensive runs. There is an absolute dearth of major-league talent.

The Braves aren't looking to contend this year, so no help is on the way. Freeman's counting stats, specifically runs and RBIs, will suffer all year long and could even get worse if his bat cools down. As an offense unto himself, he's the cornerstone of Atlanta's rebuild, but as a fantasy asset, Freeman's value has nowhere to go but down.
