Second baseman Mookie Betts, Boston's No. 5 prospect, drove in two runs on Saturday as Double-A Portland beat the Trenton Thunder, 4-3. He snared a line drive in the ninth inning and started a game-ending double play.
But for the first time in a while, Betts did not get on base. The infield prospect's on-base streak ended on Saturday afternoon at 66 games.
Betts' average this season fell to .383 as he went 0-for-4 while driving in two runs on a pair of RBI groundouts.
Including last season's Carolina League playoffs, Betts' streak actually reached 71 games, which matched a streak Kevin Youkilis put together in 2003 and one Kevin Millar ran from 1997-99, with some time in the Majors in between.
Betts is ranked No. 53 on MLBPipeline.com's Top 100 Prospects list. He is batting .383/.452/.591 with six home runs, 26 RBIs and 18 stolen bases in 37 games this season. The 21-year-old has recorded more walks (21) than strikeouts (13).
Betts enjoyed a breakout season in 2013, hitting .314/.417/.506 with 15 homers, 65 RBIs and 38 stolen bases in 127 games split between Class A Greenville and Class A Advanced Salem.
