Gavin Hollowell: Everything you need to know

Hollowell (undisclosed) was activated from the 7-day injured list Saturday. Hollowell missed nearly three weeks after picking up an unspecified injury. He didn't show any signs of rust in his return to the bump Saturday, striking out a pair in a scoreless inning of relief work at Triple-A Iowa.

Triple-A Iowa placed Hollowell on its 7-day injured list April 12 due to an unspecified injury. Hollowell possesses a spot on the Cubs' 40-man roster, but his injury will take him out of the running for a promotion to the big club anytime soon. The righty reliever made three appearances for Iowa prior to landing on the shelf, working 4.2 innings and striking out nine batters while allowing two earned runs on three hits and four walks.

The Cubs optioned Hollowell to Triple-A Iowa on Friday, Patrick Mooney of The Athletic reports. Hollowell will fall short of making the Opening Day roster. The 28-year-old appeared in seven regular-season games last season and posted a 2.57 ERA with a 12:2 K:BB across seven innings this spring.
