Cecchini, the Red Sox's No. 4 prospect, finished the night 4-for-4 with a triple, two runs and two RBIs. It was his first four-hit game since April 8, 2013.
Shortstop Devan Marrero and first baseman Travis Shaw, the Red Sox's Nos. 11 and 19 prospects, respectively, also helped lead the offense Thursday. Marrero went 2-for-4 with a double and an RBI, while Shaw doubled and scored twice.
The run support was more than enough for Barnes, the Red Sox's No. 12 prospect. He struck out six batters, walked none and held Syracuse to three hits. He threw 101 pitches and earned the victory.
Thursday's victory had much less late-inning drama than Pawtucket's win in Game 1. Cecchini, ranked No. 58 on MLBPipeline.com's Top 100 Prospects list, also starred in that game, delivering a bases-loaded, walk-off single in the 10th inning to give Pawtucket a 2-1 victory.
Pawtucket now takes its 2-0 lead in the semifinals on the road, as the best-of-five series moves to Syracuse on Friday for Game 3. The game, which begins at 7 p.m. ET, can be seen on MiLB.TV. Games 4 and 5, if necessary, will also be played in Syracuse.
