Betts continuing torrid stretch at Double-A Portland

Second baseman Mookie Betts, the Red Sox's No.5 prospect and No. 58 overall by MLB.com, continued his torrid start to the season Tuesday, helping Double-A Portland to a 10-2 victory against Reading.

Betts went 3-for-4 with a home run and scored two runs in the win. He extended his hitting streak to 15 games and has now reached base safely in 55 consecutive games, including last season's Carolina League playoffs.

Betts broke out last season, hitting .314 with 15 home runs and 38 stolen bases between Class A Greenville and Class A Advanced Salem. He followed that up with a successful stint in the Arizona Fall League, where he hit .271 and helped Surprise win the championship.

A promotion to Portland this season hasn't slowed Betts down. In 21 games, he has gone hitless just once and is hitting .422 with a .689 slugging percentage. His home run Tuesday was his fourth of the season, and he has stolen 10 bases.

Betts wasn't the only player ranked in MLB.com's Top 20 Red Sox prospects list who helped Portland's offense Tuesday. Catcher Blake Swihart (No. 3) tripled and scored a run, shortstop Deven Marrero (No. 13) added two hits and Travis Shaw (No. 19) hit his fourth home run of the season.
