Analysis: Lopez's velocity was down throughout spring training, and while it ticked back up in his season debut against the Padres, he managed just one strikeout. It's the third arm-related stint on the IL for Lopez since last year's All-Star break. Bryce Elder has taken Lopez's spot on the roster and will start in his place Wednesday versus the Dodgers. Lopez will be eligible for activation in mid-April, but his absence is likely to extend beyond that.
