Mariners rookie Tony Zych made his big league debut Friday night in Oakland against the A’s. The 25-year-old right-hander from Chicago became the last man, alphabetically speaking, in major league history.

Zych threw two scoreless innings in long relief, then allowed a pair of baserunners in his third frame before exiting. Those runners later scored, giving him a 9.00 career ERA.

It won’t look like an A-plus line on baseball-reference.com, but at least Zych has his name etched in baseball history, even if you have to go to the very end to find it.
