Darvish was pitching capably, albeit not at the All-Star level of previous years, before right elbow inflammation put him on the shelf at the end of August. A bone spur was discovered, ending his campaign, and at the time Darvish and his doctor could not rule out a cleanup procedure in the offseason. Darvish, now 37, has a history of elbow trouble including Tommy John surgery in 2015 and a stress reaction in 2018. He owns the record for the most strikeouts by a Japanese-born pitcher in MLB history, though his dominance has been fading in recent years (25.1 K% over the past two seasons). The team context is a mark in his favor, particularly the dimensions of Petco Park, but it's becoming increasingly tougher to justify the dice roll on his health with the skills in decline. The bone spur looms as a major concern -- surgery to shave or remove the spur would not necessarily solve all of Darvish's problems at this stage. Per his doctor, such a procedure could make the elbow too loose and open the right-hander up to other potential issues. Read Past Outlooks
