Angels manager Kurt Suzuki said Saturday that Klassen (back) is unlikely to return this season, Jack Janes of TheSportingTribune.com reports.
While Klassen's bullpen sessions have been going well, the Angels have no reason to rush him back at this stage. Klassen made four starts in August in his return to the big club, posting an encouraging 2.01 ERA and 1.21 WHIP over 22.1 innings. He should compete for a spot in the starting rotation in spring training, health permitting.
