Soriano got hurt while diving for a ball last night against the San Diego Padres.
The Cubs mulled putting the five-time All-Star on the 15-day disabled list, even though an M-R-I today revealed no major structural damage.
Instead, they optioned right-handed pitcher Angel Guzman to Triple-A Iowa just before today's game against the Padres. The Cubs called up top prospect Felix Pie, who started in center and batted leadoff in his major-league debut.
Soriano was a key component in the Cubs' off-season overhaul. He's batting .245 with no homers and one R-B-I after signing for eight years and 136-million dollars.
