Arrieta debut: Due to the rainout on Tuesday in Cincinnati, right-hander Jake Arrieta's season debut got pushed to Saturday as he missed the first month of the season due to shoulder stiffness. A healthy Arrieta has dominating stuff although he tends to walk too many hitters. He could pitch himself into being a core player for the Cubs. That's what this season is about for him.
Who's hot/Who's not: Starlin Castro and Anthony Rizzo finished the first month of the season in fine fashion. They were on base a combined nine times on Wednesday night. Castro was 9-for-20 on the just completed road trip while Rizzo redeemed himself from a rough week by getting on base five times in the finale against the Reds. Meanwhile, Mike Olt continues to struggle as he was 1-for-12 on the road trip, including an 0-for-5 with two strikeouts on Wednesday although he made contact with the bases loaded to drive in a run. His batting average is down to .164.
Sunday's game: The Cubs' first Sunday night game is featured on ESPN with Dan Shulman and John Kruk broadcasting from the right field bleachers. They'll sing the seventh inning stretch as well.
