MLB Heat Check: July 23rd, 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.
