C Tuffy Gosewisch was 2-for-4 with two singles in his first start of the season after being recalled from Triple-A Reno on Friday. C Welington Castillo had homers in his previous two games, but he could benefit from a break, manager Chip Hale said. "It's hard to catch three days in a row in this league, and he's been taking a beating on foul tips," Hale said of Castillo. Gosewisch was hitting .342 with nine homers at Reno. "He deserves a chance to show us what he's got," Hale said.

C Tuffy Gosewisch was recalled from Triple-A Reno when LF Rickie Weeks Jr. was placed on the bereavement list. Gosewisch was hitting .342 with 13 doubles, nine homers and 26 RBIs for the Aces. He recently was named to the Pacific Coast League all-star team, and he leads league catchers with a 41.5 caught stealing percentage.

Gosewisch's season came to a close in late May when he sustained a torn ACL in his left knee. Thus, this move was merely procedural in order to open up a spot on the 40-man roster.

Gosewisch (knee) will undergo surgery to repair his torn ACL in his left knee Friday.

Gosewisch had already been ruled out for the rest of 2015 after tearing his ACL, so this is just a bookkeeping note. Jarrod Saltalamacchia and Welington Castillo figure to see the bulk of the starts at catcher in Arizona going forward.

Gosewisch (knee) has been diagnosed with a complete tear of his ACL and is done for the season.

Gosewisch suffered the injury last week running to first base. It brings to an end his first season as the D-Backs' starting catcher, during which he posted a .211/.261/.281 line. Arizona will turn to Jarrod Saltalamacchia and Jordan Pacheco behind the plate. Gosewisch should be ready for spring traniing next year.

Gosewisch indicated Friday (knee) he has likely suffered a left ACL tear, Steve Gilbert of MLB.com reports.

Gosewisch's stint on the disabled list would be a long one if he's indeed suffered the tear he believes is the issue.

Arizona Diamondbacks catcher Tuffy Gosewisch indicated Friday that the left knee injury he suffered Wednesday is likely a torn ACL, according to MLB.com. Gosewisch injured the knee while running the bases and stayed down for quite some time before being helped up and off the field. The 31-year-old has not yet been officially diagnosed with a torn ligament, but his season would undoubtedly be over if that does turn out to be the case. In 38 games this year, Gosewisch is batting just .211 with one home run and 13 RBI, but has been a steady fielder and an asset to the pitching staff. Gosewisch is currently on the 15-day disabled list as he undergoes more tests, but the team has already called up catcher Jarrod Saltalamacchia from the minors to share the catching duties with Jordan Pacheco while Gosewisch is out.

The report doesn't elaborate on the extent of the injury, and while there hasn't been anything to indicate that it's this serious, an ACL tear would end Gosewisch's season. For now, Gosewisch will be replaced on the roster by Jarrod Saltalamacchia, who figures to split playing time with Jordan Pacheco.
