Lux was placed back on the taxi squad after serving as the 29th man for Thursday's doubleheader against the Giants, Eric Stephen of SBNation.com reports.
Lux started Game 2 of the twin bill and went 0-for-3 with a pair of strikeouts. The 22-year-old will rejoin the Dodgers' taxi squad and should remain the top option to nab a roster spot if Los Angeles needs another infielder.
