Worth noting

• When Neil Walker followed up his Opening Day 10th-inning homer with his tie-breaking single in the ninth inning Monday night, he became the first Pirates player in the last 40 seasons to have two walk-off hits in one April.

• The Bucs began Tuesday night's game six games behind National League Central leader Milwaukee. In 2013, they never trailed in the standings by more than four games.

Jason Grilli, aka "Grill Cheese," will observe National Grilled Cheese Month on Wednesday by serving -- what else? -- grilled cheese sandwiches at the Greater Pittsburgh Community Food Bank to Pittsburgh area food bank clients. Land O'Lakes, Inc. is donating 40,000 pounds American Cheese product for the initiative that will provide over 33,000 meals to families in need.
