SAN DIEGO — Boston Red Sox catcher Jason Varitek has joined fellow catcher Victor Martinez on the disabled list, the Boston Globe reported Thursday night.

Varitek has a fractured foot.

WBZ-Channel 4 in Boston reported that Varitek sustained a leg injury and showed footage of Varitek’s charity miniature golf event Thursday night, in which he was limping.

Martinez is on the 15-day DL with a fractured left thumb.

In a related move earlier Thursday, the Red Sox acquired catcher Kevin Cash from the Houston Astros for infielder Angel Sanchez.

The 32-year-old Cash played for the Red Sox in 2007 and 2008. Cash hit .204 with two home runs and four RBIs for Houston. The Astros designated him for assignment on June 22 and no team made a move to get him.

Sanchez played in one game for Boston. He hit .274 for Triple-A Pawtucket. The Astros recently lost rookie shortstop Tommy Manzanella for six weeks because of a finger injury.

Diamondbacks fire manager GM

PHOENIX — The Arizona Diamondbacks fired manager A.J. Hinch and general manager Josh Byrnes on Thursday night.

Arizona was 31-48 and in last place in the NL West, 15½ games back of San Diego entering Thursday’s games.

Hinch was hired May 7, 2009. Despite having no managerial experience at any level, he was moved from the front office to manager following the firing of Bob Melvin. Hinch has two years remaining on his contract after this season.

Diamondbacks bench coach and ex-major league slugger Kirk Gibson will be the interim manager.

Hinch is the fourth manager to lose his job this season. Florida’s Fredi Gonzalez, Baltimore’s Dave Trembley and Kansas City’s Trey Hillman have also been fired.

Byrnes has 5½ years left on a deal that runs through 2015.

Former major league pitcher Jerry DiPoto, vice president for player development, will take over the GM duties on an interim basis.

In a statement issued Thursday night, Arizona managing partner Ken Kendrick called the firings “a significant decision, but one that we find necessary in order to achieve a direction of winning consistently on the field again.”

The team scheduled a Friday news conference to discuss the move.

Byrnes was in his fifth season as general manager after being lured from the Boston Red Sox, where he was assistant to GM Theo Epstein. After the young Diamondbacks finished with the NL’s best record and made it to the NLCS in 2007, Arizona gave him an eight-year extension.

Hinch, who has a degree from Stanford, was vice president for player personnel when he was moved to the manager’s role, even though he had never even been a coach before. At the time, Byrnes touted Hinch’s “organizational advocacy.”
