Seattle Mariners DFS Spin
Mariners shortstop J.P. Crawford drove in half of his team’s runs in their 8-5 win over the Red Sox on Wednesday. In that game, the 30-year-old left-handed hitter went 2 for 4 with a homer, 4 RBIs, a walk, and a run scored. For the season, Crawford is batting .246 with 1 homer, 10 RBIs, 1 stolen base, and an OPS of .714. J.P. Crawford is hitting .385 over his past 7 games. If the Long Beach, CA, native draws a start on Thursday, he could be worth a look in DFS.
Boston Red Sox DFS Spin
Red Sox first baseman Triston Casas drove in 60% of his team’s runs in their 8-5 loss to the Mariners on Wednesday. Hitting out of the #6 spot in the lineup, the 6’4” left-handed hitter went 1 for 3 with a homer, 3 RBIs, a walk, and a run scored. Casas is hitting .171 with 3 homers, 10 RBIs, and an OPS of .570 on the campaign. The 25-year-old from Miami is hitting .292 with an OPS of .976 in 24 career at-bats against current Mariners pitchers. That fact makes Triston Casas worthy of DFS consideration on Thursday.

Mariners vs. Red Sox Betting Prediction
I like Seattle in this matchup. Mariners right-handed starter Bryan Woo is a big reason why. Through 4 starts this season, Woo is 2-1 with a 3.12 ERA, a 1.04 WHIP, a 3.7 strikeout-to-walk ratio, and a .221 opponent batting average. What’s more, Bryan Woo has thrown a quality start in 3 out of his 4 trips to the hill this year. I like Woo to toss another quality start on Thursday as the Mariners get an outright win at Fenway Park. The pick is Seattle +140 on the money line over Boston at Bovada.lv.
