Effross is likely to be a member of the Cubs' Opening Day bullpen, Jordan Bastian of MLB.com reports.
Effross made his MLB debut last season and pitched in 14 games for Chicago. He performed pretty well, registering a 3.68 ERA, 0.95 WHIP and 18 strikeouts across 14.2 innings. Jonathan Holder, Ethan Roberts and Michael Rucker are a few of the other pitchers vying for bullpen spots in camp, though it seems like Effross has a leg up at this point.
