Los Angeles Angels first baseman Matt Thaiss will look to shake loose from a 1-for-20 slump heading into this week's fantasy action. Thaiss hit five home runs and posted a .600 slugging percentage in the month of July but is off to a very slow start this month. The rookie has struck out seven times over his last 20 at-bats and will need to make adjustments at the plate. Thaiss has dynasty value but, right now, cannot help fantasy rosters win games.
