As coach Glenallen Hill (born March 22, 1965) is an American former Major League Baseball outfielder.

Hill played with the Toronto Blue Jays (1989–91), Cleveland Indians (1991–93), Chicago Cubs (1993–94, 1998–2000), San Francisco Giants (1995–97), Seattle Mariners (1998), New York Yankees (2000), and Anaheim Angels (2001) during his thirteen-year career.

He committed to attend Arizona State University[4] where he had received scholarship offers to play both baseball and football.

The following year, Hill suffered a dislocation fracture of his left wrist while diving for a sinking liner on May 26th.

Hill was the first National League player to serve as a designated hitter in regular season play, doing so on June 12, 1997, in the first-ever game in interleague play as his San Francisco Giants faced the Texas Rangers at The Ballpark at Arlington.

Hill signed with the Mariners on January 8, 1998, and hit .290 with 12 homers and 33 runs batted in before being placed on waivers and claimed by the Cubs.

Hill also played in one game during the 1998 National League Division Series where he was one for three with a run batted in and a stolen base.

[6] On May 11, 2000, Hill became the first, and thus far only player to hit a home run on the three-story residential building across the street from Wrigley Field at 1032 W. Waveland Ave.

He hit 16 home runs in a rotating designated hitter role and was added to the postseason roster.

In the 2000 American League Championship Series against the Seattle Mariners, Hill played in two games and went 0 for 2, striking out in both of his plate appearances.

In a 13-year major league career, Hill compiled a lifetime batting average of .271, hitting 186 home runs and driving in 586 RBIs in 1,162 games.

[8] In 2007, Hill started wearing a helmet while coaching first base following the death of Tulsa Drillers (a Rockies minor-league affiliate) first base coach and former major leaguer Mike Coolbaugh from injuries sustained when hit in the head by a batted ball.

As an employee of Major League Baseball, Hill was required to submit to an interview by the Mitchell investigators.

During the interview, Hill denied having used the HGH provided by Radomski, citing that he had been suffering from marital stresses at the time.

In a February 2008 joint press release with Matt Herges issued by the Colorado Rockies, Hill admitted to having used steroids.

[16] When he awoke from the incident, he had cuts on his hands and feet due to walking across shards of broken glass from a table he knocked over and also fell down a flight of stairs.

[17][18] In April 2017, as manager of the Albuquerque Isotopes, he allowed a giant pink-toed tarantula to crawl on his arm during a team media day to demonstrate he was not arachnophobic.
