PHOENIX (Reuters) - Baseball Hall of Famer Frank Robinson was released from an Arizona hospital on Thursday after being admitted earlier in the day with an irregular heartbeat.

Robinson, 75 and a senior vice president of Major League operations, became dizzy during a meeting of owners and general managers near Phoenix, Major League Baseball said on its official website (www.mlb.com).

But after a battery of tests, Robinson was released and allowed to return to his hotel.

"The doctor said I was a little dry -- not dehydrated -- and my heart rate was 190 (beats per minute)," Robinson told MLB.com. "I began getting concerned sitting there when my heart started to beat faster.

"I thought it was kind of temporary and I tried to wait it out, but it just kept going and going. Finally I just decided to get out of there and have it checked. And I'm glad I did."

Robinson played 22 seasons in the big leagues and became the first African American manager in the Major Leagues when the Cleveland Indians hired him as a player-manager in 1975.

He later managed the San Francisco Giants, Baltimore Orioles and Montreal Expos/Washington Nationals.
