Frank W. "Dutch" Ulrich (November 18, 1899 – February 11, 1929) was a Czech-American professional baseball player who played three seasons for the Philadelphia Phillies from 1925 through 1927.

He would emerge as one of Philadelphia's best pitchers in 1927, only posting an 8–11 record but finishing among the NL's ERA leaders despite the fact that his team lost 103 games.

The following year, he pitched one game for the Quebec Bulldogs of the Class B Eastern Canada League, though an exact record of how he fared is unavailable.

Recently acquired catcher Walt Lerian, who became good friends with Ulrich, noticed that the pitcher's velocity, location, and control were the best of all the ballplayers he had caught in semipro ball that year.

[6] Uhlrich appeared in 35 games in 1924 as a starting pitcher for the Waterbury Brasscos of the Class A Eastern League, posting a 17–13 record.

[5] Uhlrich ranked among the Eastern League leaders with 17 wins (tied with Kent Greenfield and Moose Fuller for seventh), a 2.87 ERA (sixth), and 276 innings pitched (ninth).

He made his major league debut with them on April 18, pitching a scoreless inning and striking out a batter in a 14–13 victory over the Boston Braves.

[7] On June 30, he relieved Huck Betts to start the ninth inning of a game in which the Phillies trailed the Brooklyn Robins by a score of 9–7.

[10] After that, he did not complete another start until the second game of an October 3 doubleheader, when he gave up nine hits but no runs in a 3–0 victory over the Giants, his first major league shutout.

[4] He made 45 appearances for the Phillies in 1926, tied with Jakie May for the fourth-highest total among NL pitchers (behind Jack Scott's 50 and Claude Willoughby's and Pete Donohue's 47).

He got future Hall of Famer Kiki Cuyler to hit into a double play which scored a run but ended the inning.

Future Hall of Famer Lloyd Waner hit into a fielder's choice to score a run, and Cuyler came to bat again.

In the first, he held the St. Louis Cardinals to four hits but suffered the loss, as future Hall of Famer Jesse Haines threw a shutout.

Ulrich and Lerian would never play together in the major leagues, however, because the pitcher missed the 1928 season with an illness contracted in February.

The illness kept him confined to Franklin Square Hospital for several weeks, but later in the year, he was able to begin training in hopes of recovering enough to pitch again in 1929.

Though newspaper articles said he had died of pneumonia and pleurisy, tuberculosis and cardiac exhaustion were the actual causes, according to the death certificate.
