Hartline Every week, when we scan the scoring leader boards in fantasy, there are a few guys names that pop up that are unowned.

We take a look at their percentage of ownership and we wonder, why is this guy only owned in 10 percent of leagues.

Lots of times it's because a player had fluke breakout game, sometimes a player steps in for an injured player and does exceptionally well.

Do these performances warrant an add to your fantasy team?

Take a look at these top five performances from players owned in less than 10 percent of leagues and see if you should add them.

Top Five

WR Brian Hartline, Miami: Week 4 @ Arizona: 12 receptions, 235 yards, 1 touchdown: Rank 1st 2.3 percent owned

Hartline had a nice career game, and seems to have a decent rapport with quarterback Ryan Tannehill. He was targeted 18 times throughout the game and did catch an 80-yard touchdown pass.

This is the second 20-plus point game that Hartline has put up so far this season. I think it is safe to assume that Hartline is the go-to-guy in Miami in the passing game. However he has put up two clunkers against tougher defenses. He only had three catches for 50 yards against Houston and once reception against the Jets.

With Sunday's performance, Hartline is 10th in the NFL in receptions and leads the NFL in receiving yards. If he's still on the waiver wire in your league, which he should be, I would go ahead and pick him up. He's not a safe play every week, but he looks like he will put up big numbers against weaker defenses.

WR Andre Roberts, Arizona: vs. Miami: 6 receptions, 118 yards, 1 touchdown: Rank 4th 1.3 percent owned

Roberts may actually be proving to be a No. 2 caliber receiver in the NFL, and may also be making a case to be an addition to your fantasy roster as a flex option. With his two touchdown catches against the Dolphins, Roberts now has four touchdowns on the season.

This was his first 100-yard performance of the year, but he has at least racked up 50 receiving yards In three out of four games this season.

Make no mistake Larry Fitzgerald is still the main man on this team, but if teams are going to blanket him, Roberts looks like he will be an intriguing option from here on out.

RB Jackie Battle, San Diego: Week 4 @ Kansas City: 15 carries, 39 yards, 4 receptions, 42 yards, 2 touchdowns (1 rushing, 1 receiving). Rank 4th 8.2 percent owned.

Even with Ryan Mathews returning, Battle still looks like he will be heavily involved in the offense. Granted he will be on a time-share situation with Ryan Mathews, but he looks to be a fantasy contributor. This is the second double-digit points game Mathews has put up and he now has three rushing touchdowns and a receiving touchdown to boot.

These were the first receptions on the season for Battle, which if continued will boost his fantasy value even more. He will still get his carries, granted they will probably diminish to around 8-10, but he looks like he may be a touchdown vulture. Handcuff him to Mathews if you have not already.

RB Brandon Bolden, New England: Week 4 @ Buffalo: 16 carries,137 yards, 1 touchdown: Rank 6th .2 percent owned

Both Bolden and Steven Ridley were able to rush for over a 100 yards against the Bills' defense, the difference was it took Ridley 22 carries and Bolden only 16.

This is the first week where Bolden was used with any consistency and part of that may have had to do with revamping the gameplan due to losing tight end Aaron Hernandez. Bolden wasn't all that impressive during preseason and the Bills defense just basically gave up,allowing not only two 100-yard rushers, but two 100-yard receivers (Gronkowski and Welker).

I would hold off on picking up Bolden, those in deep leagues that may need running back help may be tempted to add him to the roster, but this game was an absolute massacre in regards to the amount o yards the Bills gave up. See how he gets used next week before making him the new addition to your team.

WR James Jones, Green Bay: Week 4 vs New Orleans: 5 receptions, 56 yards, 2 touchdown: Rank 12th 9.5 percent owned

People are always a little leery about adding a Packer receiver to their roster. Aaron Rodgers tends to spread the ball around to everyone and other than maybe Jordy Nelson, no one appears to be a consistent target. However, James Jones has proven to be that consistent guy.

The last two games he has caught five passes and has gone over the 50-yard receiving mark. He also has three double digit points games, so you can't ignore Jones no longer.

The knock on Jones is that he drops to many passes, but so does most of the Green Bay receiving corp (Jermichael Finley takes the brunt of that argument usually). However, the Packers are a pass-happy offense, and don't seem to go to the ground game unless they absolutely have to.

Plus with Greg Jennings' groin injury lingering, Jones is going to continue to see consistent playing time, which should translate to more points. Go ahead and add him.
