According to the Baseball-Reference uniform number database, Onelki Garcia was the first player to appear in a major league game wearing #98.
If Garcia were a Yankee, they’d retire the number just to be on the safe side.
The Baseball-Reference Play Index says Garcia is the 21st pitcher in their database whose career started by walking the first batter he faced and then being pulled.
Darren Oliver made his major league debut on September 1, 1993 and issued an intentional walk, and then got pulled. Not all four of Oliver’s pitches were intentional walks. Billy Hatcher was on first, stole second and opened up a base, so Rangers manager Kevin Kennedy (did you know he used to manage in the big leagues) had Oliver walk Mike Greenwell and then brought in Mike Schooler to retire Luis Ortiz to get out of the inning.
Two pitchers, Tom Baker of the 1963 Giants and Art Reinhart of the 1919 Cardinals, started their careers by hitting the first batter they faced. In Reinhart’s case, he hit the first batter he faced with his first pitch and then didn’t appear in the majors again until 1925. (I had looked up this info earlier on some microfilm for someone else. I just didn’t know it.)
Four pitchers started their career by giving up a home run to their first batter in relief and then got pulled. Actually, Andy Messersmith wasn’t pulled. He came into relief in a game for the Angels back in 1968 against Boston in a bases loaded, no out situation in a 1-1 tie and gave up a grand slam to Ken Harrelson. You can put it on the board….
