DIEGO MORENO, YANKEES, RHP
Age: 27 | Drafted: Signed as an amateur free agent in 2006 (by Pirates)

Age: 24 | Drafted: 2nd round in 2009 (by Braves)
Debut: June 28

Despite giving up a home run to his first batter, Matz went 7.2 innings, allowing two earned runs and striking out six. But the most memorable part of his debut was his work at the plate, going 3-for-3 with four RBIs in the Mets' 7-2 victory. Matz pitched another gem in his follow-up start, but was sidelined with a tear of his lat muscle in his left side.
ROB REFSNYDER, YANKEES, 2B
Age: 24 | Drafted: 5th round in 2012
Debut: July 11
With Stephen Drew hitting below the Mendoza line, the Yankees called up the Korean-born infielder to start on the road against the Boston Red Sox. In his debut Refsnyder went 0-for-3, grounding into a double play, hitting a soft lineout and popping out to first.
MICHAEL CONFORTO, METS, OF
Age: 22 | Drafted: 10th round in 2014
Debut: July 24
As Michael Cuddyer's balky left knee didn't get any better and the Mets' offense sputtered along, the team called up Conforto from Double-A Binghamton looking for a jolt. He debuted against the Los Angeles Dodgers at home on July 24 and hit a hard groundout to first base in his first at-bat. In his second appearance, he recorded his first career RBI with a fifth-inning groundout. He grounded out in the seventh inning for a hitless debut in the Mets' 7-2 loss.
CALEB COTHAM, YANKEES, RHP
Age: 27 | Drafted: 5th round in 2009
Debut: July 29
With the Yankees trailing Texas, 4-2, Cotham replaced lefty reliever Chasen Shreve and allowed his baserunner to score. But Cotham bounced back to strike out Elvis Andrus to end the seventh, and then in the eighth allowed a runner to reach second but ended the threat by fanning back-to-back hitters. He ended his debut with four of his five outs coming via strikeout.
NICK GOODY, YANKEES, RHP
Age: 24 | Drafted: 22nd round in 2011
Debut: July 30

LUIS SEVERINO, YANKEES, RHP
Debut: Aug. 5
Luis Severino delivered five solid innings for the Yankees in his long-awaited debut, but the Yankees' offense couldn't get it going in a 2-1 loss to the Red Sox.

GREG BIRD, YANKEES, 1B
