MLB Heat Check: August 13th, 2013
Whether you’re looking for a guy that’s due or you put your faith in players hitting the ball well, recent performance is a crucial factor in daily fantasy baseball. But it’s not just about finding which players are putting up the biggest numbers, because in DFS it comes down to value. In this article I’ll look at which players are over/under performing their season averages by the greatest margin in recent days.

For the purpose of this article, we’ll define hot and cold streaks by players recent averages (last SEVEN days) vs. their season averages. We’re far enough into the season that, for the most part, we have a decent feel for where players lie. The four key stats looked at in terms of differentials will be:
1) Batting Average
2) Slugging Percentage
3) OPS (On Base + Slugging)
4) Fantasy Points Per Game (based on FD scoring)
Also, to qualify, hitters must have at least 50 plate appearances on the season and 10 plate appearances over the past seven days.
Shown below are the hitters with the largest fantasy point per game differentials between their last 7 days performance and their season averages, along with the percentage increase or decrease for each stat.
HOTTEST HITTERS
| Josh Reddick | HOTTEST HITTER #1 |
| Season | Last 7 Days | Difference | Percent Change |
| AVG | 0.214 | AVG | 0.286 | AVG | 0.072 | AVG | 33.6% |
| SLG | 0.383 | SLG | 1.000 | SLG | 0.617 | SLG | 161.3% |
| OPS | 0.680 | OPS | 1.400 | OPS | 0.720 | OPS | 105.9% |
| FPPG | 2.24 | FPPG | 6.04 | FPPG | 3.80 | FPPG | 169.2% |
- Easiest way to make this list? Have a .214 season average then hit 5 home runs in the span of 2 days. That’s just the Josh Reddick way.
- I think this is a clear “unsustainable” streak. He’s probably better than his numbers indicate this year, but his price went through the roof after this weekend’s dong-fest.
| Brian Dozier | HOTTEST HITTER #2 |
| Season | Last 7 Days | Difference | Percent Change |
| AVG | 0.245 | AVG | 0.379 | AVG | 0.134 | AVG | 54.7% |
| SLG | 0.428 | SLG | 0.897 | SLG | 0.468 | SLG | 109.4% |
| OPS | 0.728 | OPS | 1.308 | OPS | 0.580 | OPS | 79.7% |
| FPPG | 2.37 | FPPG | 5.64 | FPPG | 3.27 | FPPG | 137.8% |
- Dozier is a guy whose price is finally sitting at a point where he should probably be avoided. He’s been really good against lefties though and is definitely worth paying up for in those situations.
- His .310 BA against LHP and .271 average at home make him a guy to target in that specific situation and fade in others.
| Aaron Hill | HOTTEST HITTER #3 |
| Season | Last 7 Days | Difference | Percent Change |
| AVG | 0.304 | AVG | 0.478 | AVG | 0.174 | AVG | 57.2% |
| SLG | 0.530 | SLG | 1.000 | SLG | 0.470 | SLG | 88.5% |
| OPS | 0.879 | OPS | 1.520 | OPS | 0.641 | OPS | 72.9% |
| FPPG | 2.81 | FPPG | 6.00 | FPPG | 3.19 | FPPG | 113.8% |
- He’s not just hot over the last week, he’s hitting .417 in August and his daily fantasy price has risen to boot. He’s now the most expensive 2B on the majority of sites.
- I think we’re seeing the norm rather than an unsustainable trend for Hill. Obviously he won’t continue hitting at this pace but he was injury hampered in the early part of the season but, when healthy, is one of the best hitting second basemen in baseball.
- He has a .950 OPS at home and a 1.100 OPS against lefties. That’s a nice place to spend up on Hill. But he’s also boasting an OPS over .800 on the road and against righties so he’s never a bad option.
| Jayson Werth | HOTTEST HITTER #4 |
| Season | Last 7 Days | Difference | Percent Change |
| AVG | 0.328 | AVG | 0.529 | AVG | 0.201 | AVG | 61.3% |
| SLG | 0.530 | SLG | 0.882 | SLG | 0.353 | SLG | 66.5% |
| OPS | 0.922 | OPS | 1.519 | OPS | 0.597 | OPS | 64.8% |
| FPPG | 3.03 | FPPG | 6.20 | FPPG | 3.17 | FPPG | 104.9% |
- Another Werth streak, yawn.
- All I’ve really learned about this guy is that if he’s hot enough to make it into this article, you’re already too late.
- The .571 BA in August is impressive I suppose. Fire away with Werth against lefties as well. He has 8 HR in 71 AB’s against as opposed to 9 HR’s off righties in over 250 AB’s.
| Leonys Martin | HOTTEST HITTER #5 |
| Season | Last 7 Days | Difference | Percent Change |
| AVG | 0.278 | AVG | 0.333 | AVG | 0.055 | AVG | 19.8% |
| SLG | 0.407 | SLG | 0.417 | SLG | 0.010 | SLG | 2.4% |
| OPS | 0.716 | OPS | 0.761 | OPS | 0.045 | OPS | 6.3% |
| FPPG | 2.09 | FPPG | 5.17 | FPPG | 3.07 | FPPG | 146.9% |
- He was the flavor of the week last week, and his %owned went way up across the board. Unfortunately, his price followed suit.
- As I mentioned last time I wrote this article and he was mid-hot streak, the 25 year old loves playing at home and he can’t hit lefties.
HONORABLE MENTION – HOTTEST
COLDEST HITTERS
| Raul Ibanez | COLDEST HITTER #1 |
| Season | Last 7 Days | Difference | Percent Change |
| AVG | 0.246 | AVG | 0.091 | AVG | -0.155 | AVG | -63.0% |
| SLG | 0.504 | SLG | 0.091 | SLG | -0.413 | SLG | -82.0% |
| OPS | 0.801 | OPS | 0.182 | OPS | -0.619 | OPS | -77.3% |
| FPPG | 2.57 | FPPG | -0.17 | FPPG | -2.74 | FPPG | -106.5% |
- This had to be the most obvious downfall ever right? I don’t know what kind of vitamins he took in the first half but I need some STAT.
- In all seriousness, the dong or bust Ibanez was bound for a cold streak. The whole Mariners offense seems to go as he goes and right now, they’re all pretty cold.
| Troy Tulowitzki | COLDEST HITTER #2 |
| Season | Last 7 Days | Difference | Percent Change |
| AVG | 0.303 | AVG | 0.050 | AVG | -0.253 | AVG | -83.5% |
| SLG | 0.555 | SLG | 0.050 | SLG | -0.505 | SLG | -91.0% |
| OPS | 0.920 | OPS | 0.290 | OPS | -0.630 | OPS | -68.5% |
| FPPG | 3.07 | FPPG | 0.46 | FPPG | -2.60 | FPPG | -84.9% |
- Tulo has been battling some injuries (what else is new) so I’ll cut him a break though.
- I can’t help but notice his struggles are coming off of a lengthy road trip, I think a few Coors will do him well.
| Buster Posey | COLDEST HITTER #3 |
| Season | Last 7 Days | Difference | Percent Change |
| AVG | 0.300 | AVG | 0.067 | AVG | -0.233 | AVG | -77.7% |
| SLG | 0.489 | SLG | 0.067 | SLG | -0.422 | SLG | -86.4% |
| OPS | 0.845 | OPS | 0.267 | OPS | -0.578 | OPS | -68.4% |
| FPPG | 2.44 | FPPG | 0.30 | FPPG | -2.14 | FPPG | -87.7% |
- I give up on the Giants. Guess what? They suck at hitting. Next.
| Mark Trumbo | COLDEST HITTER #4 |
| Season | Last 7 Days | Difference | Percent Change |
| AVG | 0.235 | AVG | 0.040 | AVG | -0.195 | AVG | -83.0% |
| SLG | 0.451 | SLG | 0.040 | SLG | -0.411 | SLG | -91.1% |
| OPS | 0.749 | OPS | 0.117 | OPS | -0.632 | OPS | -84.4% |
| FPPG | 2.57 | FPPG | 0.50 | FPPG | -2.07 | FPPG | -80.6% |
- Almost as nauseating as seeing another Giants player on the coldest list is seeing an Angels guy.
- Trumbo has and always will be a high-risk, high-reward play. He could dong (like he already has done tonight) or K 17 times. Roll the dice at your own risk.
| Jason Kipnis | COLDEST HITTER #5 |
| Season | Last 7 Days | Difference | Percent Change |
| AVG | 0.290 | AVG | 0.222 | AVG | -0.068 | AVG | -23.4% |
| SLG | 0.482 | SLG | 0.296 | SLG | -0.185 | SLG | -38.5% |
| OPS | 0.844 | OPS | 0.596 | OPS | -0.248 | OPS | -29.4% |
| FPPG | 3.25 | FPPG | 1.25 | FPPG | -2.00 | FPPG | -61.5% |
- Kipnis was once a main stay of the “hottest” section of this article but recent struggles have pushed him all the way to the opposite end of the spectrum.
- His .222 batting average isn’t all that disappointing but the OPS under .600 is definitely concerning. He’s just not picking up extra bases which, when he was hot, was something he did almost nightly.
