Maybin is slashing .235/.333/.351 with six home runs this season. He has 29 steals, which is his best mark in six seasons. Maybin is now tied for the American League lead in stolen bases with Jose Altuve, which means the Astros now have the top two basestealers in the AL.
The deal comes at an important time, as players must be acquired before midnight ET to become eligible for postseason rosters.
The Astros' acquisition could spell less playing time for rookie left fielder Derek Fisher and defensive ace Jake Marisnick.
