Nick Kurtz became the first major league rookie to hit four homers in a game, leading the Athletics to a 15-3 victory over the Houston Astros on Friday night.

A four-game sweep at the hands of the last-place A’s at Daikin Park highlighted a depleted lineup and saw another starting pitcher join baseball’s longest injured list.

Kotsay mentioned Royals rookie Jac Caglianone, who was drafted two spots after Kurtz in last year’s Draft and landed on the injured list with a hamstring strain on Sunday, as a cautionary tale.
