The 25-year old was on a whirlwind tour after he got the call to join the Cubs on Friday night when Steve Clevenger suffered a right oblique strain and was placed on the disabled list on Saturday. Castillo not only arrived in Philadelphia from Triple-A Iowa on Saturday, he was promptly inserted into the starting lineup for the game against the Phillies due to Geovanny Soto dealing with back tightness.
"He's more of an everyday catcher, and that's what he was doing in Iowa, so we'll probably use him more," Cubs manager Dale Sveum said. "He'll start tonight, just because we'd prefer not to have [Soto start] and the back flare up, then we're with one catcher the rest of the game."
Castillo hit .286 (65-for-227) with 15 home runs last season in the Pacific Coast League. This year, he's hitting .320 (16-for-50) with four doubles and a pair of home runs with Iowa.
