Texas now has home-field advantage throughout the playoffs, including the World Series, because the AL won the All-Star Game in July.
Even if the Rangers lost their remaining two games and Boston or Cleveland were to catch them in the standings, they hold the head-to-head tiebreaker over both clubs, guaranteeing Texas the top seed.
The Rangers are 53-26 at Globe Life Park this season with two home games remaining.
