Marte has been shut down from throwing with Triple-A Lehigh Valley due to a shoulder injury, Corey Seidman of NBC Sports Philadelphia reports.
Seidman relays that the injury is serious enough that Marte could be done for the rest of the regular season. Marte's last outing in Triple-A was Sept. 5 against Buffalo, during which he gave up three runs on three hits and one walk over one inning. The 29-year-old right-hander appeared in 23 games for the Phillies this season and posted a 6.92 ERA and 1.88 WHIP over 26 innings.
