Rays place lefty Shane McClanahan, righty Matt Wisler on 10-day injured list

Tightness in Shane McClanahan’s back has forced the Rays to place the rookie southpaw on the 10-day injured list on Friday. The injury is minor, however, and the Rays plan to have McClanahan back in the rotation as of September 19, per Marc Topkin of the Tampa Bay Times.

McClanahan has made 22 starts for the Rays, which puts him first on the team in that category, while he’s second in innings pitched with 110 1/3 frames. Those innings have largely been quality: McClanahan has posted a 3.59 ERA/3.23 FIP with a strikeout rate roughly 4 percent better than average and a walk rate roughly 1 percent better than average.

In the meantime, Louis Head was recalled from Triple-A, and Chris Archer will move back into the rotation to start Saturday’s game against the Tigers. The 31-year-old Head is in his first season with Tampa, a year in which he’s made his major league debut and posted a 2.93 ERA/3.52 FIP in 27 2/3 innings. Archer has yet to find his groove, but he did soak up five innings during his last start on September 4.

In less promising news, Matt Wisler could be sidelined for the rest of the season due to inflammation in his middle finger. The team is hopeful he sees some improvement after a 10-day shutdown, but the outlook doesn’t look promising. Wisler has been stellar since joining Tampa from the Giants, pitching to a 2.30 ERA/2.17 FIP over 27 1/3 innings.

If Wisler is out for the year, the Rays could replace him with a familiar face: Nick Anderson should join the active roster for the first time this season on Sunday, per Topkin. That the Rays have succeeded as they have without Anderson all year speaks to their pitching depth. Anderson was a crucial piece of their pen last season and could be again if he appears on track heading into the postseason. Anderson has been out all year with a partial ligament tear in his elbow.
