Withrow was optioned back to Triple-A on Friday to make room for Edinson Volquez, and normally wouldn't be eligible to return for 10 days without replacing a player on the disabled list but since Albuquerque's season is over that rule goes by the wayside.
But Withrow is alone among Dodgers call-ups on Tuesday, as pitcher Javy Guerra, infielders Elian Herrera and Justin Sellers, and outfielder Alex Castellanos were all left behind even though they are on the 40-man roster.
Withrow has been a pleasant surprise for the Dodgers this season, putting up a 3.38 ERA and 28 strikeouts in 24 innings, with just eight walks, including 17 strikeouts against just three walks in 15 innings since the All-Star break.
Walks have always been an issue for Withrow, the Dodgers' 2007 first round pick who transitioned from starting to relief midway through 2012 in Double-A Chattanoga. But the stuff as always been there, as his average fastball of 96.4 mph and devastating slider have shown. Withrow's slider, per FanGraphs, has been over four runs better than average per 100 pitchers, the seventh best slider among MLB relievers with at least 20 innings this season.
Withrow, 24, was 4-0 with a 1.71 ERA in 25 games with Albuquerque this season, with 33 strikeouts and 13 walks in 26⅓ innings in his first stint in Triple-A. He has pitched just once in the last eight days, throwing a scoreless inning for the Isotopes on Sunday in New Orleans with one walk and one strikeout.
