Double-A Binghamton received big contributions from a pair of Mets' prospects as the Rumble Ponies topped Reading 6-2 on Sunday.
David Thompson, the Mets' No. 23 prospect, hit a pair of homers, while Chris Flexen (Mets' No. 24) gave up one run over seven innings and matched his season high with eight strikeouts.
Thompson, 23, has six homers this season and a pair of two-homer games in his career after his impressive 3-for-3 game on Sunday. The third baseman hit a solo homer in the fourth and a two-run blast in the eighth and is 4-for-6 over the past two games, bumping his season average up to .245 through 61 games.
Meanwhile, Flexen is new to the Double-A level, but the inexperience doesn't seem to be hindering the 22-year-old righty.
After posting a 2.13 ERA through three starts with Class A Advanced St. Lucie this season, Flexen was promoted to the Rumble Ponies, where he has gone 2-1 with a 1.74 ERA through three starts. Flexen has pitched into the seventh inning in each of those three outings and has recorded a quality start in all three.
Other top prospect performances from Sunday's action:
• No. 42 overall prospect Nick Gordon (Twins' No. 1) extended his hitting streak to 12 games with a pair of doubles for Double-A Chattanooga. Gordon finished the afternoon 2-for-5, scored a trio of runs and is hitting .315 through 64 games in his first taste of Double-A ball.
• No. 68 overall Justus Sheffield (Yankees' No. 6) spun his first career shutout (7 innings) as he led Double-A Trenton to a 6-0 win over Erie in Game 1 of a doubleheader. Sheffield, who has won back-to-back decisions and has a 2.99 ERA through 13 starts, gave up just three hits and walked one. Sheffield threw 62 of his 97 pitches for strikes in the game, but notched just three strikeouts, his lowest total this season.
"I hold myself to a high standard every time out there and every time I'm out there, I'm shooting for the limits," Sheffield told MiLB.com. "I knew we had seven [innings] today and I wanted to get seven in. … I feel like if you set yourself at a high standard, you'll be able to be efficient, keep the pitch count low and pitch deep into games. That's one of my goals this year."

Castillo gave up 1 earned run on two hits in 6 1/3 innings.
"He was on top of his game, he pitched in and out," Pensacola pitching coach Danny Darwin told MiLB.com. "He pitched down in the zone, he pitched up in the zone. He had a big league changeup and threw some very good sliders."
