After graduating from Hazelwood West High School, Phelps went to Notre Dame, where as a sophomore, he struck out 102 batters while posting a 1.88 ERA. After going 5-5 with a 4.65 ERA and 75 strikeouts as a junior, he was selected by the Yankees in the 14th round of the 2008 amateur draft. He was signed by scout Mike Gibbons and made his pro debut that summer, posting a 8-2 record and 2.72 ERA in 15 starts for the Staten Island Yankees. He began 2009 with the Charleston RiverDogs going 10-3 with a 2.80 ERA in 19 starts. He was promoted to the Tampa Yankees in late July and went 3-1 in 7 starts for the club, allowing just 5 earned runs in that time.
Phelps was with the AA Trenton Thunder to start 2010 and was 6-0 with a 2.04 ERA in 14 starts. He again advanced up the Yankees ladder in early July, joining the Scranton/Wilkes-Barre Yankees, and went 4-2 with a 3.07 ERA in a dozen outings. He spent the majority of 2011 back with Scranton/Wilkes-Barre, where he posted a 6-6 record and 3.19 ERA in 18 starts. After missing two months of the season with a shoulder injury, he also got into a pair of games with the GCL Yankees on a rehabilitation assignment that summer.
Phelps made New York's Opening Day roster in 2012 and got into his first game on April 8th, coming out of the bullpen and retiring both batters he faced to end the game against the Tampa Bay Rays. Phelps retired the first 12 batters of his career, but the streak was ended by a Vernon Wells home run. He continued to pitch quite well over the next few months, assuring his place as the swingman and long reliever out of the Yankees' bullpen.
On December 19, 2014, he was traded to the Miami Marlins along with Martin Prado in return for Nate Eovaldi, Garrett Jones and Domingo German. His 2015 season with the Marlins was a bit of a disappointment, as he was only 4-8, 4.50 in 23 games, including 19 starts. He pitched 112 innings, but had a good K/W ratio at 77/33. His season ended early when he was diagnosed with a stress fracture in his right forearm on August 18th. It wasn't clear how the injury had occurred, but he had had to leave his final start of the season, on August 16th after only 2 1/3 innings because of discomfort. When he came back in 2016, he was mainly a reliver, though, making only 5 starts among his 64 appearances. He went 7-6 with an excellent ERA at 2.28 and 114 Ks in 86 2/3 innings. He also recorded 4 saves.
Phelps continued to pitch well in 2017, even if he was not as dominant as the year before. In 44 games for Miami, all in relief, he was 2-4, 3.45 with 51 strikeouts in 47 games. With the trade deadline approaching, his name was mentioned as one of the more interesting relievers on the market, thanks to his recent success and the fact that he was under contract at a very reasonable salary for another year and a half. This explains why the Seattle Mariners were willing to give up four players to acquire him on July 20th.
