Bryce Harper Injury UpdateGirardi said Harper is expected to receive a PRP injection in his elbow this weekend that will likely keep him out of the lineup on Sunday and Tuesday.The injury will not impact his hitting, according to the Pro Baseball Docs – including former Texas Rangers head team physician Dr. John Conway.Harper likely suffered the UCL damage on this throw on April 11.This was a great effort but Bryce Harper, but the Mets still go up 4-0. pic.twitter.com/DSxx0unuWZ— Phillies Nation (@PhilliesNation) April 12, 2022 Harper appeared to be in pain and was grabbing at his elbow after the failed throw home in the seventh inning, but stayed in the outfield for the rest of the game. Girardi said after the contest that his elbow was ok, and he continued to play right field through April 16. His elbow was re-evaluated on May 4 after he was diagnosed with a right flexor strain and had yet to be cleared to throw at the time.Further tests revealed the torn UCL.He has not missed time with the injury but has started at DH in each of the last 22 games, something that was made possible by the institution of the universal DH as part of this spring's collective bargaining agreement. The reigning NL MVP is batting .295 with a .911 OPS, six home runs, nine doubles, 21 runs, 18 RBI, and 26 strikeouts in the 27 games since the errant throw on April 11.Harper's absence will be a blow to an already-abysmal Philadelphia fielding team. The Phillies are tied for the ninth-worst defensive unit in the league and have committed 20 errors this season.Phillies World Series OddsAt 14-17, the Phillies are +800 to win the NL East and +2500 to win the World Series, according to FanDuel Sportsbook.
