Roth, 24, has seen Major League time with the Halos in each of the past two seasons, although the former ninth round pick has yet to replicate his minor league success in the Majors. Roth pitched to an 8.76 ERA in 12 1/3 innings this season and has a 7.79 mark in a total of 32 1/3 big league innings. However, his numbers at Double-A this year were a significant improvement, as he posted a 2.62 ERA with 5.1 K/9 and 3.4 BB/9 in 140 2/3 innings as a starter. This marks the second time the Angels have designated Roth, although the pitcher himself seems to be in good spirits about the move based on this tweet.
Williams, 28, was claimed off waivers from the Rockies less than a month ago. Selected 43rd overall by the Giants in 2007, the former Sooner is a .235/.307/.361 hitter in five seasons at the Triple-A level and made his big league debut with the Rox in 2014. Williams twice ranked among the Giants’ top 30 prospects, according to Baseball America, placing 18th and 16th, respectively, following the 2007 and 2008 campaigns. BA listed him as the best defensive catcher in San Francisco’s system on three separate occasions, most recently before the 2011 season.
