Underwood was drafted by the Detroit Tigers in the first round of the 1976 Major League Baseball draft, as the second pick overall. His older brother, Tom was also a pitcher.

Underwood spent the next several seasons in the Tigers' farm system. He had a record of 6âÂÂ2 in 1976 with the Advanced A level Lakeland Flying Tigers in the Florida State League and an earned run average of 2.22. Underwood split the 1977 season at different levels in the minors, spending the first half of the year at Montgomery in the AA Southern League, where he had a record of 9âÂÂ2 and an ERA of 3.38 with 64 strikeouts in 104 innings of work.

Tom found the whole thing stupid, but the brothers brought their best. Pat did not give up a hit until the fifth inning. Tom allowed four hits and struck out four in keeping the Tigers scoreless through seven. Then, Tigers center fielder Jerry Morales led off the eighth with a home run. Pat pitched into the ninth before handing the game over to the bullpen with one out. For Tom, it was a complete game loss.
Underwood also started against the Chicago White Sox on the famed Disco Demolition Night at Comiskey Park, going innings and giving up just one run in what was supposed to be game 1 of a doubleheader. With the Tigers, he had a 6âÂÂ4 record and an ERA of 4.59 with 83 strikeouts in 27 appearances.
