Corey Seager Over 0.5 hits (-220)
Seager is batting .269 at the plate with 15 homers, 38 RBI, and 76 total hits on the season. His over/under for hits on DraftKings is 0.5, and he’s gone over that number in 12 of his last 15 games.

Cal Raleigh Over 1.5 total bases (-105)
Raleigh is currently first in the MLB in home runs (41) and tied for first in RBI (87), while being third in OPS (.972). The 28-year-old has totaled at least two bases in three of his last five games. On July 28 against the A’s, he went 2-of-4 with one run driven in. The SportsLine model projects Raleigh to finish with 1.8 total bases on Thursday.
George Kirby Under 5.5 strikeouts (+100)
Thus far into the season, Kirby is 5-5 with a 4.50 ERA and 68 K’s. DraftKings has his strikeout over/under at 5.5, but he’s posted under that mark in six of his last 10 outings.
