Original headline: Joshua Báez becomes the FIRST PLAYER EVER to hit THREE HOME RUNS in his MLB debut!
They’ve been playing major league baseball more than 150 years, and nobody had ever done this before. The kid hit a 449-foot homer to center on his first MLB pitch – and he was just getting started. He didn’t merely hit three homers in the game; he did it in his first three plate appearances!
UPDATE: Baez is now 6-for-41 (.146). He has only had three hits since that first game, so he has batted .081 (3-for-37) in that stretch, with one additional homer. Several of you guys suggested that his first game was the ultimate flash-in-a-pan, a case of a guy who just happened to get hot at exactly the right moment. It seems that you guys were correct. Will that game be his entire highlight reel, ala Keith McDonald (see below). I guess we have to stay tuned to find out.
Two previous players had homered in their first two at-bats. One was a solid ballplayer, but the other was a career minor leaguer whose first two major league at-bats were little short of miraculous.
* Bob Nieman stayed in the majors 12 years after he accomplished the feat in 1951. He was a good hitter (.295 lifetime with an OPS+ of 132), but he never made the all-star team, and never reached as many as 75 RBI in a season.
* An obscure catcher, Keith McDonald, did it in 2000. His entire major league career consisted of only 9 at-bats, although he did add one more homer before he headed back down to Memphis. Three homers in nine at-bats gave him a lifetime slugging average well over 1.000! That performance was a total fluke. He kicked around the minor leagues for 13 years and averaged only six homers per year! In fact, he hit more homers in his 9 major league at-bats than he did in an entire season in the Florida State League in 1996, when he had 410 at-bats!
