AL West Notes: Scheppers, Nuno, Guerrero

Rangers reliever Tanner Scheppers will have surgery on his left knee to repair torn articular cartilage, and he will be unavailable for the first half of the season, MLB.com’s T.R. Sullivan writes. Scheppers suffered a bone bruise in his left knee last year, but the Rangers don’t think his current injury is related. “He woke up a few days ago and the knee was a little puffy,” says GM Jon Daniels. “He can’t think of a moment where he tweaked it.” Scheppers, 29, pitched 38 1/3 innings last season, posting a 5.63 ERA with 7.5 K/9 and 5.4 BB/9. Here’s more from the AL West.

• Mariners manager Scott Servais says lefty Vidal Nuno will pitch only in relief this Spring, MLB.com’s Greg Johns tweets. (Servais also notes that the same is true of Danny Hultzen, although that had previously been reported.) Nuno arrived from Arizona in the Mark Trumbo / Welington Castillo deal last June and posted a 4.10 ERA, 7.5 K/9 and 2.0 BB/9 in four months in Seattle. The 28-year-old was far more successful (1.91 ERA) in 37 2/3 innings in relief than he was in 51 1/3 innings as a starter (5.08 ERA), and he had a large platoon split, so he might ultimately prove most useful to the Mariners coming out of the bullpen.
• Longtime Expos and Angels star Vladimir Guerrero will return to the Halos this spring as a guest instructor, Guerrero himself tweets. The 41-year-old Guerrero has been out of affiliated baseball since playing briefly in the Blue Jays’ minor league system in 2012. He signed, but never played, with the independent Long Island Ducks in 2013 before officially retiring with the Angels in 2014. He has, however, remained on the periphery of the game, with his son Vladimir Jr. now a top Jays prospect.
