Chicago Cubs RP Hector Rondon's slider has improved and made his fastball more effective, according to manager Rick Renteria. Rondon has allowed two earned runs over eight innings in his last nine appearances. Renteria noted Rondon's slider was flatter and as fast as his fastball earlier in the season. "The last couple of days, all of us have noticed him using the slider a little more effectively and it's got more depth. He's been working on it," Renteria said. Renteria believes Rondon has the potential to be a consistent closer.
