Douglas Randall Sisk (born September 26, 1957), is an American former Major League Baseball relief pitcher.

From there, he spent two more seasons with the Washington State University Cougars before signing as an amateur free agent with the New York Mets in 1980.

[1] In his first season of professional baseball with the Kingsport Mets, Sisk went 8–5 with a 2.66 earned run average as a starting pitcher.

Over three seasons in the Mets' farm system, Sisk was 25–14 with a 2.88 ERA, sixteen saves and 170 strikeouts to earn a September call up in 1982.

Sisk made his Major League debut on September 6 against the Pittsburgh Pirates, pitching a scoreless inning.

[2] On September 15, he faced one batter, Andre Dawson, in an extra innings contest with the Montreal Expos.

[3] Over the remainder of the season, Sisk pitched six innings, and allowed just one hit, picking up his first career save on September 22 against the Chicago Cubs.

[5] Seaver pitched six scoreless innings, matched by fellow future Hall of Famer Steve Carlton.

[8] He was effective upon his return (9.1 IP, 2 ER), but was by then a target of the Shea Stadium boo birds despite ending the season with a 2.09 ERA.

By then, Roger McDowell had emerged as the right-handed closer for the Mets, and Sisk was pretty much relegated to "mop up duty."

Shortly after his return, he pitched his best game of the season (4 IP, 1 hit) for his second save,[11] This was followed by three consecutive losses, the second of which came against the rival St. Louis Cardinals.

A rough month of July (5.30 ERA) cost him the trust of manager Davey Johnson, and he spent the rest of the season pitching almost exclusively in blowouts.

Sisk had a decent 1987 season (3–1, 3.46 ERA, 3 SV), but was still being used for mop up duty by Davey Johnson, and was still drawing the ire of the fans.

After posting a 7.04 ERA in eight appearances with the triple A Colorado Springs Sky Sox, he was released, and re-signed with the Mets.

[20] He was part of the notorious "Scum Bunch" as a Met, along with Orosco and left fielder Danny Heep.
