10 Fantasy Baseball Players to Buy and Sell for Week 13

Sell Nomar Mazara

If you look at Nomar Mazara's raw numbers, you see a talented hitter with a .273/.338/.474 slash line, 14 homers and 52 RBI, coming off back-to-back seasons with 20 dingers and, last season, a year in which he crossed the 100 RBI plateau.

But the batted-ball data indicates his homer pace may not be sustainable. Mazara has seen a big-time jump in his ground-ball rate this year to 55.0%, up from his career average of 49.2% and way up over last year's 46.5%. Meanwhile, his fly-ball percentage has dropped to 23.6% this year, down from 34.2% last year and a career mark of 30.3%.

So how is he hitting so many homers? A much larger percentage of his fly balls are leaving the yard, 26.9%, 5th-highest in the AL, and way up from 13.6% last season and his career 16.8% mark. Selling him before that number reverses itself might be the wise choice.
