It’s not clear at what point an abnormal level of play becomes normal, but the A’s have to be getting close to that point after a 6-5 loss to the Twins Thursday.
Manager Bob Melvin shook up his infield Thursday, putting second baseman Eric Sogard at shortstop and third baseman Brett Lawrie at second base so regular shortstop Marcus Semien could get a day off.
And the A’s paid for it when the first four runs of the Twins win scored after one error by each middle infielder.
“Marcus had played every inning of every game,’’ general manager Billy Bean said.
