Red Sox pitching prospect Matt Barnes made his major-league debut Tuesday, giving up three hits and striking out two in three scoreless innings of relief in his team's 4-1 loss to the Orioles.

Barnes threw a whopping 30 of his 38 pitches for strikes in the debut performance. It was a nice showing after he went 8-9 with a 3.95 ERA and 103:46 K:BB ratio in 127 2/3 innings with Triple-A Pawtucket.
