Jacob’s deGrom’s season is already off to a rocky start, as an MRI Thursday revealed a stress reaction in his right shoulder.The news is concerning for multiple reasons, and potentially signals another injury-riddled season in 2022 for the two-time Cy Young winner, forcing the ProBaseballDocs to drop his SIC Health Score down to 62 heading into his age-34 season.He developed shoulder tightness after playing catch recently then went for the MRI. The injury is obviously not directly connected to his UCL, but is likely stemming from having to adjust his throwing motion to compensate for the repeated and various right arm issues. deGrom will not throw for four weeks, then will be rechecked. At this point, he would be lucky to return to the mound in six weeks. The Docs questioned whether or not the previous elbow issues would affect deGrom this season, as injuries beget injuries, and the ace's shortened 2021 season was a perfect example of that.deGrom’s 2021 campaign was upended by a host of various injuries, the last and most concerning of which was right elbow soreness that turned out to be a UCL strain, or partial tear. He also dealt with right lat, shoulder, and forearm tightness, ailments that began in early May and ended with the Mets shutting down deGrom in July 7, at which point he was maintaining a 1.08 ERA, 0.554 WHIP, and 146 strikeouts in 92 innings across 15 starts.Last we heard from both Mets’ brass and deGrom himself, the issue resolved itself, and the 33-year-old ace said earlier this month that his UCL is fully healed. deGrom underwent Tommy John Surgery – done to repair significant UCL injuries – in 2010 after his first season in the minors. He had another surgery in 2016 to reposition the ligament, and has gone on to win two Cy Youngs while leading the majors in strikeouts twice and ERA once since. If deGrom had elected to undergo another UCL procedure last year or during the offseason, he likely would have missed the entire 2022 season. With deGrom potentially out for an early stretch of the season, the Mets will have to rely on newly-acquired starters Max Scherzer and Chris Bassitt.The ProBaseballDocs hate to be negative in our outlook, but it’s clear that the nearly nine months away from the mound and his offseason regiment did not solve the issue.The worst, therefore, seems to have happened, which is that the injuries leak into yet another season, which is set to begin next Thursday.Hopefully, he can get through the inflammation, tighten up his throwing motion to avoid further injuries, and return to his elite pre-injury form, but these early issues are a harbinger of things to come.
