Rox shuffle Senzatela back into rotation

DENVER -- The Rockies will continue to juggle their rotation as manager Bud Black tries to limit his young starters' innings. The latest shift will see Antonio Senzatela put back in the mix.
Senzatela will return from Triple-A Albuquerque to start Tuesday against the Padres, Black said. The rookie right-hander made one start with the Isotopes, throwing 60 pitches in 3 1/3 innings while giving up one run on four hits. He'd made two relief appearances after being bumped from the rotation June 22 to conserve his arm.
Senzatela threw just 34 2/3 innings in 2016 with Double-A Hartford and made the jump to the Majors this season. He's thrown 96 2/3 total innings this year between Colorado and Albuquerque.
Additionally, Tyler Chatwood's calf strain threw a wrinkle into the plans. The Rockies will jump over his scheduled spot for Friday and go right to rookie Jeff Hoffman, Black said. The team's Thursday off-day will allow Hoffman, who last started Sunday vs. the Mets, to stay on regular rest.
Jon Gray, who started the Rockies' second-half opener, will start Wednesday's finale vs. the Padres.
Worth noting
• The Rockies also shook up their bullpen, optioning lefty Zac Rosscup to Albuquerque and recalling righty Jairo Díaz.
Rosscup made two appearances for the Rockies this season after being called up July 8. Both outings came over the weekend vs. the Mets, and he gave up one run on four hits in three innings. In Friday's opener in New York, Rosscup entered with the bases loaded and all three runners scored.
Diaz missed all of 2016 after undergoing Tommy John surgery in March that year. He threw one inning for the Rockies earlier this season, giving up three runs on four hits vs. the Giants.
