Here are four interesting items from around the big leagues Thursday:
• Francisco Liriano kept the Tigers off the board for seven frames, and the Pirates completed a three-game sweep with an 8-4 victory in Detroit. As a team, Pittsburgh owns a historic 2.91 ERA. The club has entered the All-Star break with a sub-3.00 ERA only once: in 1968. That year, Ron Kline, Bob Veale and Co. compiled a 2.65 ERA.
