Few Waiver Claims Contributing So Far

A number of non-tenders are adding value in the Major Leagues this year, as I showed earlier today. Waiver claims – at least so far – haven’t had close to the same success. Former top prospects such as Brandon Wood and Max Ramirez haven’t produced and neither have most of the 30-plus players who have been claimed since last season. Here’s a look at the few waiver claims who have made an impact in the Majors this year:

• Phil Humber (White Sox, from Royals, via Athletics) – The 28-year-old former top draft pick has a 3.18 ERA with 5.2 K/9 and 2.2 BB/9 through 45 1/3 innings. Now a member of Chicago's six-man rotation, Humber is finally providing value in his sixth MLB season.
• Pat Neshek (Padres, from Twins) – Neshek is back on the Padres' active roster after a quick stint in the minors. He posted a 1.86 ERA with 10 strikeouts in  9 2/3 innings earlier this year. Padres reliever Samuel Deduno (from Rockies) gets an honorable mention, though he's not on San Diego’s active roster.
• Joe Mather (Braves, from Cardinals) – A longtime favorite of the Braves, Mather has a .747 OPS after 24 plate appearances and has appeared at three positions. With respect to Mather, his presence on this list shows how little other waiver claims have impacted MLB rosters so far in 2011.
