Quick Hits: Chapman, Giants, Stroman

The Reds have announced that they have reinstated closer Aroldis Chapman from the disabled list. He will immediately move back into his usual ninth-inning role, C. Trent Rosecrans of the Cincinnati Enquirer tweets. Chapman had surgery to insert a metal plate into his head after being struck with a line drive in spring training. He made two rehab appearances for Triple-A Louisville this week. Here are more notes from around the big leagues.

• Outfielder Tyler Colvin has been promoted to the Giants, Alex Pavlovic of the Mercury News tweets.  Colvin had been hitting .267/.315/.408 in 130 plate appearances for Fresno. Brandon Belt, meanwhile, is headed to the disabled list with a broken thumb, and CSN Bay Area’s Andrew Baggarly writes that Belt could be out six weeks. Mike Morse will be the Giants’ starting first baseman until Belt returns, ESPN’s Jim Bowden tweets. The Giants also activated Matt Cain and optioned pitcher George Kontos to Triple-A Fresno.
• Marcus Stroman of the Blue Jays is appearing as a reliever in his first stint in the big leagues even though he started in the minors, Ben Nicholson-Smith of SportsNet.ca notes. That’s a little bit unusual for a promising starting pitcher, but it’s not totally without precedent — Earl Weaver favored having rookie pitchers begin their careers in the bullpen, and the Cardinals frequently have top young starters pitch in relief in their first seasons. “We have been a very competitive team for the last ten years and we typically have had strong rotations,” says Cards GM John Mozeliak. “Getting pitchers to begin their careers in the bullpen allows them to experience the major league hitters, ballparks, and experience.” Mozeliak also adds that having young starters pitch in relief prevents them from becoming overworked. On the flip side, Nicholson-Smith points out, having an excellent young pitcher in the bullpen blunts his impact — having Jose Fernandez start his career in relief would have cost the Marlins wins, for example.
