Diamondbacks transferred C Oscar Hernandez from the 15-day disabled list to the 60-day disabled list.
The move clears a spot on the 40-man roster for the addition of Jarrod Saltalamacchia. Hernandez is out with a broken left hamate bone and a timetable for his return isn't known.
Diamondbacks placed C Tuffy Gosewisch on the 15-day disabled list, retroactive to May 28, with a left knee injury.
Gosewisch injured the knee while trying to beat out an infield single on Wednesday. It's not clear at this point how long he'll be sidelined. Jarrod Saltalamacchia has taken his spot on the roster and there's a good chance Gosewisch won't have his starting job when he returns.
Diamondbacks purchased the contract of C Jarrod Saltalamacchia from Triple-A Reno.
Saltalamacchia hit two homers in nine games for Reno but batted just .188/.222/.375 overall. However, with Tuffy Gosewisch (knee) going on the disabled list the Snakes needed another body behind the plate. Salty should get the bulk of the starts while Gosewisch is out and his power makes him worth an add in two-catcher leagues.
Blue Jays sent RHP Todd Redmond outright to Triple-A Buffalo.
Redmond has been knocked around for 11 runs over 8 1/3 innings for the Jays this season. He'll provide Triple-A depth.
Jason Hammel's next scheduled start has been pushed back from Saturday to Sunday.
Hammel has been dealing with a fingernail issue on his pitching hand, and although it doesn't seem like a big deal, the Cubs are using the opportunity to give him an extra day of rest. He's flip-flopping spots with Tsuyoshi Wada, who moves up from Sunday to Saturday.
Devon Travis (shoulder) will begin a rehab assignment with Triple-A Buffalo on Friday.
He'll stay with Buffalo through the weekend before being activated on Monday, the first day he's eligible, if all goes well. Travis has been on the shelf since May 17 with inflammation in his left shoulder.
Alex Rios (hand) will be activated from the disabled list on Saturday.
He had been slated for a return on Friday, but the Royals have decided to give him one more day. Rios has been on the shelf since mid-April with a fracture in his left hand. Paulo Orlando is getting another start in right field Friday but is expected to be sent down when Rios is activated.
CBS Sports' Jon Heyman reports that Johnny Cueto "is at least on (the Astros') radar."
It's possible they could ultimately shoot a little lower (Heyman says that they're also considering Aaron Harang), but it sounds like there's a good chance the Astros will add a starter before the deadline. One executive noted that potential trade talks between the Astros and Reds could get interesting given the icy relationship Houston general manager Jeff Luhnow and Cincinnati GM Walt Jocketty had when together in St. Louis. Cueto is currently dealing with an elbow issue, but he was cleared of structural damage and is expected to rejoin the rotation Sunday.
