Kevin Maas appeared as the heir apparent to Don Mattingly in the summer of 1990. He was recalled from the Columbus Clippers in June and hit many home runs. He set a record for fewest games to reach ten home runs. He was helped by a three-game series against the Texas Rangers when he homered in each game of the series. Maas became the first major leaguer to hit 20+ homers, all from July 1st onwards; it would be 19 years until Garrett Jones became the second.
Maas was signed as a 22nd round pick in the 1986 amateur draft by the Yankees and scouts Greg Orr and Bill Livesey. He moved his way up the Yankee chain from 1986 to 1989 hitting 45 homers in 365 games but with 321 strikeouts. By the end of the 1990 season, Maas had hit 21 home runs in 79 major league games. In 1991 he was installed as the Yankees designated hitter. He would also spell Mattingly at first base on occasion. He did not hit home runs at the same pace as in 1990, but he did hit a respectable 23 home runs. Unfortunately, he hit just .220 with 128 strikeouts.
By 1992, Maas was back in the minor leagues. He was released by New York in 1994. He bounced around between different organizations. He briefly returned to the majors in 1995 with the Minnesota Twins but it was clear he was a "one-hit wonder." Maas then signed with the Hanshin Tigers in 1996 to replace Glenn Davis but hit only .245/.320/.386 and did not return for another year.
Maas' brother, Jason Maas, was a minor league outfielder for the Yankees.
