In a day that felt like a rollercoaster for the Yankees' shortstop situation, Triple-A Scranton/Wilkes-Barre saw Anthony Volpe struggle mightily, while Jose Caballero took a painful hit in the Bronx.

Volpe, just two games into his rehab assignment after being activated from the injured list and optioned to Triple-A on Sunday, had a night to forget in Worcester, Massachusetts. The former top prospect went 0-for-6, with his only time on base coming via a fielder's choice. But it was a baserunning blunder that had analysts scratching their heads. With two outs, Volpe took off from first base on a steal attempt as Spencer Jones roped a double off the right-center field wall. Instead of scoring easily, Volpe slowed down at second base, apparently thinking the ball might have cleared the fence. The Worcester TV analyst was blunt in his assessment: "I'm not sure how Volpe didn't score here. At two outs, you've got to be moving."

While Volpe's struggles continued in the minors, the man who took his starting shortstop job in the majors, Jose Caballero, found himself in the trainer's room after Wednesday night's 6-1 loss to the Texas Rangers at Yankee Stadium. In the third inning, with the Rangers already up 4-0, Caballero was drilled in the left elbow by a Nathan Eovaldi curveball. Though he stayed in the game, it was clear something was wrong—Caballero played the field and ran out grounders with his left arm hanging limply.

After the game, Caballero was unavailable for comment, but he relayed through Yankees Media Relations VP Jason Zillo that the pitch hit him "in a bad spot." When asked if he'd be available for Thursday's 12:30 p.m. series finale, the response was ominous: "His arm was swelling up."

For Yankees fans, it's a classic case of "be careful what you wish for." Volpe's path back to the majors might just be paved by Caballero's misfortune. But with the swelling in that left elbow, the Yankees could be facing yet another roster shuffle in an already tumultuous season.
