Injury Notes: Pomeranz, Frazier, Ellsbury, Parra, Norris, Koehler

Red Sox left-hander Drew Pomeranz exited today’s Grapefruit League start with tightness in his left forearm, though he told reporters after the game that he’s not concerned about the possibility of a serious injury (link via MassLive.com’s Jen McCaffrey). Obviously, caution is called for all the more at this stage of spring, so it’d be wise not to leap to any conclusions — particularly given Pomeranz’s comments. The 29-year-old, who is coming off of back-to-back seasons in which he posted a 3.32 ERA in over 170 frames, is a key piece of the Boston rotation. He’ll be further evaluated on Saturday.

Here’s the latest on the health front from around the game …

• The division-rival Yankees are also facing some injury issues, as MLB.com’s Bryan Hoch was among those to report (Twitter links). Of particular concern is prospect Clint Frazier, who required an MRI because he is still not recovering as hoped from a concussion. Surely the organization will exercise quite a lot of caution with the talented young player. Meanwhile, fellow outfielder Jacoby Ellsbury has been diagnosed with a mild oblique strain. There’s no indication of just how limiting the injury will be — and for good reason, as oblique problems rarely seem to progress in a predictable manner. Fortunately for the Bronx Bombers, there are still four quality players ahead of this duo on the outfield depth chart.
• Rockies outfielder Gerardo Parra, who is recovering from hamate surgery on his right hand, took batting practice on Friday, tweets Nick Groke of the Denver Post. He’s slated to face live pitching for the first time since the operation on Monday, and manager Bud Black estimated that Parra could be in a game in eight to nine days, which should still give him ample time to ramp up for the regular season. It remains to be seen just how the Rox will distribute playing time in the outfield, though Parra seems to be slated for rather extensive action so long as he remains on an upward trajectory.
• An injury forced newly signed Cardinals right-hander Bud Norris out of today’s spot start, writes Rick Hummel of the St. Louis Post-Dispatch. Norris, filling in for Carlos Martinez (who had a personal matter to attend to, per the report), exited due to hamstring spasms after allowing five runs in 2 1/3 innings of work. At this point, it’s not clear whether this issue is simply an early-spring blip or something that will cause some problems for the hurler, who recently inked a one-year, $3MM deal to join the St. Louis organization.
• If there’s a hurler whose injury sparks some immediate cause for concern, it may be Dodgers righty Tom Koehler. It was announced he’d require an MRI on his shoulder not long after he was pulled in the middle of an inning, as MLB.com’s Ken Gurnick was among those to tweet. Shoulder bursitis caused problems for Koehler last year, when he struggled to a 6.69 ERA in 72 2/3 innings. The Dodgers have planned to move the long-time starter into a full-time relief role after promising him $2MM for the 2018 season.
