McGee, 32, has been diagnosed with a left knee sprain. He has had some difficulties in that joint in the past, including a 2015 procedure to resolve a torn meniscus. The severity and anticipated timeline are not yet known.
This is the latest concerning bit of news for a Rockies relief unit that has not performed up to the level of investment that it took to compile it. McGee is one of several veteran hurlers who has struggled on a long-term deal; in his case, he’s just starting the second season of a three-year, $27MM pact after limping to a 6.49 ERA in 51 1/3 innings last year.
There have been some positive signs for McGee, who had three strikeouts through his first two outings of the regular season after carrying a 9:2 K/BB ratio in seven frames this spring. But he also coughed up nine earned runs on a dozen hits (including two home runs) in Cactus League action.
Now, McGee will need to get back to health before he’s able to resume his quest to get back on track on the hill. He joins fellow southpaw Chris Rusin on the injured list, leaving Mike Dunn and Harrison Musgrave as the left-side options for Colorado skipper Bud Black.
