DETROIT -- The Tigers, who got a boost with J.D. Martinez's return from the disabled list earlier this week, now have another major injury to overcome. Third baseman Nick Castellanos sustained a non-displaced fracture of the fifth metacarpal bone on his left hand in Saturday's 6-5 win over the Mets when he was hit by a pitch, sidelining him for at least the next four weeks.
"We're looking really at some point in early September that we'd get him back," manager Brad Ausmus said.
Castellanos was placed on the 15-day disabled list. The Tigers recalled veteran corner infielder Casey McGehee from Triple-A Toledo to fill his spot. Ausmus said McGehee and utility infielders Mike Aviles and Andrew Romine will play third base in Castellanos' absence.
"It'll probably depend on who's hot or who's pitching, some combination of that," Ausmus said. "Casey McGehee's a guy that's a proven big leaguer. He's played well at the big league level at times, and he's doing well down at Toledo, so I don't really have any hesitation playing him."
McGehee had one at-bat with the Tigers in June, grounding out as a pinch-hitter June 18 at Kansas City. He was designated for assignment after that game and accepted, hoping to get another chance later in the season.
Castellanos was hit by a Logan Verrett pitch in the fourth inning. He ran halfway to third base in pain after the impact, but stayed in the game to run the bases, scoring on an Ian Kinsler single.

"Watching him, he was kind of squeezing his hand, and he looked fine to me on the bases," Ausmus said. "But you just don't know with these non-displaced fractures, unless you get an X-ray or a bone scan. Sometimes you need a bone scan to even see it. You just don't know.
"It was certainly swollen and bruised when he got to the dugout."
Aviles replaced him in the top of the fifth.
Castellanos has enjoyed a breakout this year in his third season as a Tiger, batting .286 with 18 home runs and 58 RBIs while settling into the middle of the lineup. His midseason production especially helped the Tigers weather cold stretches in other parts of their batting order.
McGehee, signed to a Minor League contract in Spring Training to give the Tigers depth at the corners, ranks second in the International League in hitting with a .322 batting average. The 33-year-old leads the IL with 37 doubles. He also has five home runs, 49 RBIs and an .825 OPS.
McGehee was the everyday third baseman in Milwaukee from 2010-11, and again in Miami in '14, batting .287 with four homers and 76 RBIs two years ago. He split last season between the Giants and Marlins, hitting .198 with two homers and 20 RBIs in 237 at-bats.
