Diamondbacks’ Kole Calhoun (hamstring) out 6-8 weeks

Brett Davis-USA TODAY Sports

PHOENIX — Arizona Diamondbacks outfielder Kole Calhoun, who playfully fist-bumped a teenaged fan after being outreached for a foul ball last weekend, is expected to miss six to eight weeks because of an injured left hamstring.

Calhoun underwent a procedure Friday to remove a tendon in his hamstring, the team said. He suffered the injury while stealing third base in a 5-1 victory over San Diego on Tuesday.

Diamondbacks general manager Mike Hazen said NFL players have had the same operation as Calhoun, but was unsure if a baseball player had undergone the same procedure.

“My understanding of it was that not having it removed could have caused more long-term lingering issues,” Hazen said.

“This procedure allows for a quicker healing process, because you wouldn’t be waiting for that tendon to heal. Six-to-eight week range is probably a starting point,” he said.

The 33-year-old Calhoun is hitting .292 with two home runs and five RBIs.

The previous Friday, Calhoun went chasing a foul ball hit by Austin Riley in Atlanta. As Calhoun reached into the stands, the fan made the catch – because the ball was in the seats, there was no interference.

As the fan celebrated and showed off the ball, Calhoun gave him a fist bump and smiled. Calhoun kidded with the fan later in the game.

Royals fire manager Mike Matheny after 65-97 end to season

KANSAS CITY, Mo. – Manager Mike Matheny and pitching coach Cal Eldred were fired by the Kansas Cty Royals on Wednesday night, shortly after the struggling franchise finished the season 65-97 with a listless 9-2 loss to the Cleveland Guardians.

The Royals had exercised their option on Matheny’s contract for 2023 during spring training, when the club hoped it was turning the corner from also-ran to contender again. But plagued by poor pitching, struggles from young position players and failed experiments with veterans, the Royals were largely out of playoff contention by the middle of summer.

The disappointing product led owner John Sherman last month to fire longtime front office executive Dayton Moore, the architect of back-to-back American League champions and the 2015 World Series title team. Moore was replaced by one of his longtime understudies, J.J. Picollo, who made the decision to fire Matheny hours after the season ended.

Matheny became the fifth big league manager to be fired this year.

Philadelphia’s Joe Girardi was replaced on June 3 by Rob Thomson, who engineered a miraculous turnaround to get the Phillies into the playoffs as a wild-card team. The Angels replaced Joe Maddon with Phil Nevin four days later, Toronto’s Charlie Montoyo was succeeded by John Schneider on July 13 and the Rangers’ Chris Woodward by Tony Beasley on Aug. 15.

In addition, Miami’s Don Mattingly said late last month that he will not return next season.
