Catcher Chance Sisco, the consensus top prospect in the Orioles minor league system, will be called up tomorrow in the first wave of additions during roster expansion, according to an industry source.
Sisco, 22, will travel north from Triple-A Norfolk with designated hitter Pedro Álvarez, outfielder Joey Rickard, and reliever Jimmy Yacabonis.
A third-round pick in 2013, Sisco is batting .267 with a .736 OPS and 30 extra-base hits for the Tides. The team saw improvements in his defense under the tutelage of bench coach John Russell this year in spring training, though it still lags far behind his advanced bat.
