Arredondo burst onto the scene as a rookie in '08, posting a 1.62 ERA in 52 appearances (61 games) for the Angels. He struck out 55 against 22 walks and was credited with 10 wins in relief. The 2009 season was less kind, as Arredondo had a 6.00 ERA in 45 innings. Still, he managed 47 Ks in those 45 innings. Ineffectiveness early in the season led to Arredondo being optioned to Triple-A, and while he was down, he spent time on the disabled list with elbow problems.
Now he will have surgery to repair the elbow, and the hope is that he can roar back in 2011. Because he has less than two years of Major League experience, he will remain under the Reds' control after this season. So they are in position to reap the rewards in a year if Arredondo can return healthy and effective.
