Oh, 36, has authored a 2.68 ERA and 3.03 FIP over 47 innings this year. The Blue Jays signed him to a one-year, $2-million deal this winter that pays the veteran $1.8 million this season and includes a $2.5-million team option for 2019 with a $200,000 buyout.

The 22-year-old Wall was stationed at Double-A Hartford, where he posted a .211/.296/.367 slash line with six homers and eight stolen bases over 45 games. The former 35th overall pick was ranked as the No. 13 prospect in Colorado's system and was originally drafted as a second baseman, but has since transitioned to center field.

Spanberger, 22, was the Rockies' No. 22 prospect, according to MLB Pipeline. The lefty-hitting farmhand owned a .316/.364/.580 slash line with 22 home runs and 16 stolen bases with Single-A Asheville.

This past winter, the Rockies spent $106 million on Wade Davis, Jake McGee, and Bryan Shaw to build what was expected to become a super bullpen. The results have been underwhelming. Among National League teams, Colorado's 'pen ranks last in ERA and second-last in FIP.
