Eickhoff was placed on the 10-day disabled list with an upper back strain, Matt Gelb of The Philadelphia Inquirer reports.

EDGE Analysis

It's unclear when Eickhoff sustained the injury, as he is coming off one of his better starts of the year; a six-inning outing of one-run ball against the Diamondbacks. While the Phillies are hoping it will be a short stay on the DL, he'll be forced to miss at least one turn in the rotation. His replacement is expected to be called up from Triple-A sometime before the contest, with Mark Leiter and Mark Appel both possible options. Eickhoff owns a 4.81 ERA and 65:30 K:BB through 76.2 innings (14 starts) this season.
