2010 Overview (Tri-City + Greeneville)


Career (2006-09)


What happened?

Castillo began the year in Tri-City, and threw in three games (5.2IP, 7H/3R - 2ER - 6K:3BB) before being sent to Greeneville on June 28, where he finished the season. It was his third go-round in Greeneville, and it went fairly well, I suppose. His high-water mark was on July 7, when he allowed 2H/0ER in 4.1IP of relief of Vincent Velasquez' 1IP debut.

His K/9 rate dropped off significantly (5.8 in 2010, after a 9.1 in 2009) for his lowest K/9 rate since 2007. Meanwhile, though, his BB/9 rate dropped for the third straight year.

What went right?

Home games. In eleven appearances at Pioneer Park, Castillo allowed 20H/7ER in 23IP for a 2.74 ERA and a right-side-up GB:FB rate (1.14), holding opponents to a .238 BAA.

July. Castillo made ten appearances - including one start - in July, and in 24IP, allowed 16H/6ER, with 14K:4BB, with opponents hitting .193.

What went wrong?

August. Castillo allowed the same number of hits (20) in 10.1 August IPs as he did in June and July combined (26IP). In 10.1IP, he allowed 20H/10ER, 5K:5BB for an 8.71 ERA and a .408 BAA. Given the 1.17 GB:FB ratio, there was some adverse luck involved, but still. Also, nine of those earned runs came over four consecutive appearances.

Away games. Above we talked about how great he pitched at home. The flip-side of that are the away games, in which his road BAA was 101 points higher (.339) than his home BAa (.238), allowing 20H in 13.1IP.

Given the relative improvement - and how his season numbers came undone over the course of ten days in August, Castillo may still be in the organization come 2011, and probably in Lexington.
