DETROIT -- Tigers pitchers weren't the only ones getting restless from all the time away from the field. So was their pitching coach.
Chris Bosio had been away from the team since being hospitalized for a personal medical issue last Monday in Cleveland. But when the Tigers opened their three-game series against the Orioles Tuesday at Comerica Park, Bosio was there, back to work.
"He's back," manager Ron Gardenhire said Tuesday. "He told me he can't take it. He's fired up. He's back doing it, and he's happy to be here."
Bosio was not available for comment.
Bosio was originally expected to miss two weeks after doctors recommended he take a break. He ended up doing scouting reports and other work from home, sending them to the staff at Comerica Park while watching games on television. Bullpen coach Rick Anderson handled the in-game duties, but he will now move back to his main job, with A.J. Sager returning to the road for his duties as Minor League pitching coordinator.
It wasn't clear if doctors' recommendations on Bosio changed or if the stress of being away from the team was tougher on Bosio than the original health issue.

Tigers rotation shuffled
Bosio gets back to work with a Tigers pitching staff that spent the weekend gaining unexpected rest while also trying to get in work to keep arms fresh. Pitchers threw bullpen sessions in the indoor batting cages of Comerica Park on Sunday.
Francisco Liriano was originally scheduled to start Saturday before the weekend rainouts against the Yankees and Monday's off-day pushed him back.
Like Liriano, Matthew Boyd will be pitching on seven days' rest when he takes the mound Wednesday, as will Jordan Zimmermann when he pitches Thursday's series finale and Michael Fulmer when he starts Game 1 of Friday's day-night doubleheader against the Royals.
Daniel Norris, who has been pitching long relief since Mike Fiers' return a week and a half ago, will get a spot start when he pitches Friday's nightcap. Fiers, who pitched last Friday against the Yankees, will start Saturday.

Wilson believes in his pitching
Alex Wilson's struggles in Spring Training were nothing alarming, given his history of struggles. Once the season begins, he usually finds his command and takes his role. His recent difficulties raised the question whether his spring shadow followed him north, but Wilson believes he has been more a victim of tough luck in situations than bad pitching.
"I've been worrying," Wilson said Saturday. "Nobody wants to start the season with what I've done."
Wilson threw three scoreless innings in the Tigers' Opening Day marathon on March 30 before giving up a three-run home run to Gregory Polanco on a 3-0 pitch in his fourth frame. His other loss came last Tuesday in Cleveland, where he gave up a go-ahead home run on a 2-0 fastball to Roberto Perez.
Wilson noted he has been playing the percentages on pitches based on hitters' scouting reports.
"I'm doing everything I'm supposed to be doing," Wilson said. "I'm just not getting the results. I feel like I'm doing everything right."
Quick hits
• The Tigers have re-signed Minor League catcher Kade Scivicque, their fourth-round Draft pick from 2015, whom they traded a year later to Atlanta for Erick Aybar. Scivicque, who split last season between Double-A Mississippi and Triple-A Gwinnett, was released by the Braves earlier this month. He reported to Double-A Erie to work alongside highly regarded catching prospect Jake Rogers.
• Arvicent Perez, who had been backing up Rogers at Erie, was sent to extended spring training, where he'll get some work pitching as he explores a position change.
