This is the time of year for a top-of-the-rotation starter like Kendall Graveman to mess around with a few things he might not try during the regular season. On Monday, in his first spring outing, Graveman threw a couple of his slurvy sliders in counts he generally wouldn’t. Both of the harder-hit balls off Graveman in his two innings of work against the White Sox came on the slider. “I threw it 3-2 for a strike to see where it was right now, and obviously that’s not something I’m going to do a lot during the season,” Graveman said of the pitch Tyler Saladino smacked for a hit in the first inning. He gave up one other hit in the second on the pitch. Asked what the breaking pitch is exactly, Graveman said, “I don’t really know. Good question. Some days, it looks more like a curveball. Some days, it looks more like a slider. It’s a pitch that day by day I need to get the feel of and locate it better.”
