In Park Predictors, we look at favorable matchups for hitters and pitchers based on where they are playing this week and the MLB DW Park Factors, which look at four years' worth of data for MLB ballparks.


There could be a lot of changes with the trade deadline looming Monday. But here’s a look at the Aug. 3-9:

PITCHERS

Seattle Mariners

Lots of pitchers’ parks on the schedule this week. After a weekend at home, the Mariners have a day off, and then six more at home against the Tigers and Rays.

Detroit’s bats have struggled throughout the season. While the Rays will be coming off three games at Coors, so they could see a Rocky Mountain high dip.

Thankfully for Bryan Woo owners, he’ll be pitching at home. His splits this season have been dramatically different depending on location. At home, Woo has allowed 2.20 ERA, 0.78 WHIP, .167 batting average, .255 slugging percentage, while striking out 10 per 9 innings. On the road those numbers drop to 6.71, 1.52, .300, .477 and 8.28.
