This is one throbbing secondary pinstriped headache.

The good news for the Yankees, their first homestand in the books, is that Gary Sanchez has shown some signs of life, their biggest risk of the offseason playing like he might be salvageable.

The bad news? Another winter risk — a lesser one, it appeared at the time — has left quite a sting.

Gleyber Torres’ 10th-inning throwing error didn’t directly lead to the Yankees’ 4-3 loss to the Orioles on Wednesday night at Yankee Stadium, as the game ended in the 11th frame. Yet the shortstop’s second official miscue of the year, on top of a couple of other memorable unofficial foul-ups, lowlighted the Yankees’ first loss to the Orioles at home since May 15, 2019, ending a stretch of 12 straight wins over these guys in The Bronx.

And it intensified the scrutiny on the fourth-year player, who arrived in the big leagues as a serviceable second baseman and has struggled to transition to Didi Gregorius’ successor at shortstop even though he played there as a tot in Venezuela. If it’s obviously too early to wonder about a change at the crucial position, it’s late enough to note the problem here.
