This isn't such a big total to go Over for two American League teams. Unless those teams happen to be the Tigers and Royals.

Detroit ranks last in the American League in runs scored. The Tigers also have hit the fewest homers in the league. 

The Royals rank 11th in the AL in runs. They have hit the second-fewest homers in the AL. 

Kansas City has scored three or fewer runs in seven of its last nine games. They are facing underrated Spencer Turnbull, who has given up three or fewer runs in 12 of his 13 starts. Turnbull has held the Royals to three earned runs in 13 innings for a 2.08 ERA in two starts against them this year. 

The Under has cashed in eight of Turnbull's last 11 starts. 

Kansas City is pitching Jakob Junis, who is better than his 5.63 ERA may indicate. Junis is 6-1 with a 3.27 ERA in nine lifetime appearances against the Tigers, including eight starts.
