Senga (calf/triceps) was officially activated from the 60-day injured list Saturday, per MLB's transaction log.
The Mets made arguably the biggest headline of the postseason so far when they announced Friday that Senga would be the team's Game 1 starter versus Philadelphia in the NLDS. The right-handed hurler pitched all of one game in the majors this season, going 5.1 innings against Atlanta on July 26 and allowing two runs on two hits and one walk while striking out nine batters. Senga left that game due to a calf strain but was able to get back on the mound in time to log one minor-league rehab appearance, tossing a scoreless inning for Triple-A Syracuse on Sept. 21. It remains to be seen how deep Senga will be allowed to pitch into Saturday's game against Philadelphia given his injuries and limited workload this season.
