Rays manager Kevin Cash said Wednesday that Boxberger (oblique) suffered a setback in his recovery and won't make his Grapefruit League debut for another week or so, Marc Topkin of the Tampa Bay Times reports.
More specifically, Boxberger tweaked his lat muscle in a recent workout, but the Rays don't fear that it's anything that will dramatically delay him during spring training. The team has been taking it easy with Boxberger this spring after abdominal and oblique issues limited him to just 27 appearances with the big club in 2016. The 28-year-old has shown the ability to induce plenty of strikeouts in the past, but until he overcomes the health woes that have plagued him for the last year, he won't attract much interest outside of AL-only leagues.
