Phils Claim LHP Roberts from the Rockies

Last week, the Phillies lost left-handed reliever Cesar Jimenez when he was claimed off waivers by the Milwaukee Brewers. On Sunday, the Phillies claimed another lefty reliever, Ken Roberts, off waivers from the Colorado Rockies.

Ken Roberts hasn't had the best of seasons in 2015, at least in terms of his basic stats. He's pitched 9 1/3 innings in nine games with the Rockies this season, posting an 0-1 mark and a 5.79 ERA. At Triple-A Albuquerque, he was 1-3, 5.12 in 23 relief appearances.

When you look past the initial numbers though, you'll find some good stuff. Even with all of his struggles at Triple-A this season, he's walked just 1.1 batters per nine innings, while striking out eight per nine innings. At the major league level, he's walked just under two batters per nine and struck out just under five per nine innings. When you look at his FIP (Fielding Independent Pitching), which measures how good a pitcher is at limiting walks, hit batters and home runs and picking up strikeouts, the news is much better. His FIP at the major league level is 3.02, which basically means that he's making hitters hit their way on and picking up a good amount of strikeouts, but things like fielding and the parks that he's pitching in are lending a hand toward pushing up his ERA. Albuquerque and Colorado are two of the more unfriendly places to pitch, which could have an impact on Roberts numbers.

Over six minor league seasons, Roberts has a career mark of 22-10 with a 2.61 ERA, posting just 68 walks in 324 1/3 innings and 248 strikeouts. His career WHIP is 1.113 in the minors.

Roberts had to be added to the 40-man roster, but was able to be optioned to Triple-A Lehigh Valley. Since he is on the 40-man, it's possible that the Phillies will recall him in September for an audition with the big league club.
