Phelps allowed two runs on five hits over five innings, but did not factor into the decision as the Phoenix Desert Dogs and Peoria Javelinas played to a 2-2 tie.
Coming off picking up the AFL Pitcher of Week award, the 25-year-old Yankees right-hander finished the game with a season-high six strikeouts and did not walk a batter.
Phelps started off with four shutout innings before yielding the first two runs of the game in the fifth. Adam Moore (Mariners) and Oscar Taveras (Cardinals) recorded consecutive one-out singles, and Wilfredo Tovar (Mets) grounded out to move the runners over. Scooter Gennett (Brewers) delivered a ground-ball single up the middle to plate both runs. Fellow Milwaukee prospect Kentrail Davis followed with a groundout to second to end the frame.
The score remained 2-0 until the seventh, when the Desert Dogs got to Cardinals reliever David Kopp. Ronnier Mustelier (Yankees) led off the inning with a double, and Yan Gomes (Blue Jays) drove him in with another double two batters later. With two outs, Kevin Ahrens (Blue Jays) singled up the middle to bring Gomes in and tie the game.
Phelps ended his AFL season with a 2-2 record, totaling 28 strikeouts and nine walks in 32 2/3 innings. After posting a 9.00 ERA through his first two starts, he lowered it with each of his subsequent five outings to end at 4.41.
Selected in the 14th round of the 2008 Draft, the University of Notre Dame product put together a 3.19 ERA in 107 1/3 innings for Triple-A Scranton/Wilkes Barres this season, a mark that would have ranked sixth in the International League if he had enough innings to qualify. That is the highest ERA Phelps has compiled at any of his seven stops during his Minor League career.
With Thursday's game in the books, Peoria officially finished the season at 16-19, while Phoenix went 14-22. Both squads finished well behind the Surprise Saguaros (26-10) for first place in the West Division.
