Los Angeles Angels right-handed pitching prospect Ben Joyce was promoted to the major leagues in a corresponding move that sent left-hander Reid Detmers to Triple-A Salt Lake. Joyce held a 4.26 ERA and 1.16 WHIP across 19 innings at Double-A earlier this season. Joyce made his major-league debut last season and logged just 10 innings to the tune of a 5.40 ERA, 1.80 WHIP, and a 9:10 BB:K. However, the 23-year-old operated exclusively out of the bullpen last season. Joyce, the team's No. 4 prospect per MLB Pipeline, owns an explosive triple-digit fastball, but he's had trouble locating it so far in his professional career. He has the makings of a future closer if he can show better command.
