James Anthony Tobin (December 27, 1912 – May 19, 1969), known as "Abba Dabba", was an American right-handed pitcher in Major League Baseball with the Pittsburgh Pirates, Boston Bees/Braves and Detroit Tigers from 1937 to 1945.

The Yankees sent him back to Oakland in 1935, where he compiled an 11–8 record before tearing the cartilage in his left knee.

Rather than return to the Oaks in 1937, he arranged a deal with the Pittsburgh Pirates, with whom he made his major league debut on April 30, 1937.

He was back in the Pacific Coast League the following year, pitching for the Seattle Rainiers and the San Francisco Seals.

That year he pitched the last out against the Sacramento Solons in a game that clinched the pennant for the Oaks.

Although not leading the league, he pitched 2991⁄3 innings in 1944 [2] In the minors, Tobin won 81 games and lost 51.
