The Brewers have claimed infielder Irving Falu off waivers from the Padres, the club announced. Milwaukee designated righty Kevin Shackelford for assignment to create roster space.

Falu spent about three weeks in the San Diego organization after he was claimed from the Brewers in late June. Now, he’ll head back to Milwaukee, where he signed over the offseason after 11 seasons with the Royals. On the year, Falu has just three hits in 35 MLB plate appearances but owns a .306/.364/.361 triple-slash (with seven stolen bases against six unsuccessful attempts) over 170 trips to the plate at Triple-A. He’ll be headed back down, as the club announced that he has been optioned.

Shackleford, 25, made it onto the club’s 40-man roster to protect him from the Rule 5 draft. But after dominating High-A hitters earlier this year, he has struggled to a 6.35 ERA through 28 1/3 Double-A frames with just 3.2 K/9 against 2.9 BB/9. (In 29 1/3 innings at the level last year, he managed a 0.92 ERA with 7.7 K/9 and 2.1 BB/9.)
