ARLINGTON, Texas (AP) — The AL West-leading Oakland Athletics are headed into a frenetic stretch coming off a 6-3 loss in Texas. The A’s split the four-game series with the last-place Rangers. Now Oakland goes to Seattle for a doubleheader that will be part of four games in about 60 hours, in three cities and time zones. The three-day travel binge ends with the start of a two-game series at Colorado on Tuesday. The doubleheader was wedged between the trips to Texas and Denver after a three-game series at the Mariners to start September was postponed over COVID-19 issues.
