What is the most runs given up by a pitcher, while pitching a no-hitter?

Andy Hawkins threw an unofficial 8 inning no-hitter on 07/01/1990 and lost 4 to 0.

The most runs allowed in an official no-hitter is 2 by Ben Sanders of Louisville on 08/22/1892.

Steve Barber and Stu Miller also gave up 2 runs in a combined no-hitter on 4/30/1967.

edit: In the old American Association league Al Atkinson

(05/01/1886) and Ed Seward (07/26/1888) also gave up 2 runs in a no-hitter.

2 runs. It has been done 3 times in the MLB:

--1967

Steve Barber (8 2/3 inn.) and Stu Miller (1/3 inn.) combined for a 9-inning home loss:

Baltimore Orioles 1 Detroit Tigers 2 AL

--1914

Ed Lafitte:

Brooklyn Tip-Tops 6 Kansas City Packers 2 FL

--1892

Ben Sanders:

Louisville Colonels 6 Baltimore Orioles 2 NL

On July 21, 1970, Clay Kirby of the San Diego Padres was pitching a no-hitter against the Mets and was trailing 1-0 after the 8th inning, Don Zimmer, the Padres' manager, pinch hit for him and the reliever gave up 2 R on 3H in the 9th, what a stupid move.

Utter Chaos is right.

However, the stupidity of MLB for calling a complete-game no hitter "unofficial" because the visiting pitcher threw it makes no sense at all.

The record is Andy Hawkins. I won't entertain MLB silliness.

4 in 1990!!!
