Enerio Del Rosario is up next in our player profiles here at Climbing Tal’s Hill. Del Rosario was originally signed as an undrafted free agent by the Cincinnati Reds in 2005. Strictly a bullpen arm, Del Rosario had a pretty good career in the minors. The Reds put Del Rosario on waivers in September 2010 with the intention of sending him to Kansas City to complete the Willie Bloomquist trade, but the Astros claimed him off waivers and quickly added him to their 40 man roster.
In limited time with the Reds, Del Rosario posted a 2.08 ERA. He has a good fastball that tops out in the low 90’s but, he also has a very good power sinker that he uses as his out pitch. In 54 games for the Astros last season, Del Rosario threw 53 innings and had a disappointing 4.58 era. He also had as many walks (31) as he did strikeouts. Del Rosario could be one of those AAAA type players. His minor league stats are very good as he carried a career 2.72 ERA while striking out 270 batters and walking 108. His results at the big league level have been the complete opposite. I still think he will win a spot on the big league club, but unless he turns it around and starts pitching like he did in the minors, he could find himself demoted to AAA Oklahoma City.
