Betts is not in the lineup Thursday versus the Giants, David Vassegh of AM 570 LA Sports reports.
Betts returned from a right oblique strain Monday, which was the first of a four-game series versus the Giants. Playing in the first three games of the series, the shortstop went 2-for-13 with his third home run of the season. Miguel Rojas is instead picking up a start at shortstop in the series finale.
