Chris Davis announced his retirement on Thursday after more than a decade with the Orioles, citing his struggles coming back from injuries in a team released statement.

"After an extended time dealing with my injury and after my recent hip surgery, I informed the Orioles about my decision to retire effective today," Davis' statement reads. "I want to thank the Orioles partnership group, led by the Angelos family, the Orioles organization, my teammates and coaches, the University of Maryland Children's Hospital with whom I will continue to be involved following my retirement, and, of course, Birdland. Thank you for the many memories I will cherish forever. Sincerely, CD." 

Davis signed a seven-year, $161 million contract on Jan. 26, 2016 -- the most expensive in Orioles history. Davis will still be paid the $23 million owed to him in 2022. His last game was on Sept. 11, 2020. 

His contributions to the O's since 2016 didn't match the gaudy deal and haven't been close to the form Davis showed in 2013 when he set Baltimore's single-season home run record with 53. From 2015 to 2018, Davis led all MLB batters in strikeouts and set the record in 2019 for most consecutive at-bats without a hit (0-for-54). Since the year after Davis signed that lucrative deal, he has produced a combined .185/.272/.343 batting line, to go with 54 homers and 543 strike outs. 

Davis, 35, finishes his 13-year MLB career with 295 home runs, 780 RBIs, and a .233 batting average in 4,978 at-bats. 

"The Orioles support Chris Davis as he retires from baseball today. We thank Chris for 11 years of service to the club, to the Orioles fans, and to the Baltimore community," the Orioles statement said. 

"Athletes have the power to change lives and better their communities, and Chris and his family have done just that . We admire their dedication to those most in need, with hundreds of hours of community work completed, millions of dollars donated, and countless other charitable efforts performed, often without fanfare. 

"For every inning played and home run hit, hour of service completed and amount donated, the Davis family has made an immeasurable impact on our city and on Orioles baseball. We send our best wishes to Chris, his wife Jill, and their daughters Ella, Evie, and Grace, each of whom will forever be part of our Orioles family."
