Following his acquisition from the San Francisco Giants on May 3, 1975 Mike Phillips filled in admirably for injured shortstop Bud Harrelson. In 116 games, he hit a career high .256 with 10 doubles and team leading 7 triples while driving in 28 runs.
Phillips returned to the Mets in 1976 and served primarily as a backup infielder playing shortstop second and third base. Phillips struggled to start the season hitting just .207 over the first 2 ½ months of the season including an 0 for 21 streak. But he broke out on June 25 when he became the third player in franchise history to hit for the cycle. Phillips finished out the season with a .256 average and once again led the ream in triples with 6. He also hit 4 home runs on the season, 3 of which came during a three-game series in June, the same series in which he hit for the cycle. For his efforts, he was named National League Player of the Week
Phillips started the 1977 with the Mets but with his average at just .209 he was traded to the St Louis Cardinals on June 15 in exchange for Joel Youngblood. The trade went largely unnoticed by Met fans as it occurred on the same day the Mets traded Tom Seaver and Dave Kingman.
In his 3 seasons with the Mets Phillips appeared in 241 games and hit .250 with 6 home runs and 60 RBIs.
While with the Mets Phillips wore number 5.

San Francisco Giants – 1973-1975
