Frank Louis Bertaina (April 14, 1944 – March 3, 2010) was born in San Francisco, CA, and was a pitcher who played from 1964 through 1970 for the Baltimore Orioles (1964–67, 1969), Washington Senators (1967–69), and St. Louis Cardinals (1970).

During his minor league career, Frank led the Eastern League in winning percentage (.733) in 1964, topped the International League in strikeouts (188) in 1965, and won the International League winning percentage title (.800) in 1970.

Bertaina made his major league debut on August 1, 1964 against the Kansas City Athletics at Municipal Stadium. He started and gave up two earned runs in seven innings pitched, but did not receive a decision in the 5–2 Orioles victory.

Only one game ever has seen a double 1-hitter (each pitcher pitches a one-hitter) wherein both pitchers were major league rookies.

It happened on September 12, 1964. The rookie pitchers, both left-handers, were Bertaina, then with the Baltimore Orioles, and Bob Meyer of the Kansas City Athletics. The game was decided when John Orsino, Oriole catcher, led off the eighth against Meyer and hit a double to left center, pinch-runner Bob Savarine took third on Bertaina's bunt and scored on Jackie Brandt's sacrifice fly to right.

In Jim Bouton's "Ball Four" he notes that pitcher Moe Drabowsky nicknamed Frank “Toys in the Attic.”

Frank died in Santa Rosa, California at the age of 65, following complications from a heart attack.
