The Orioles traded their most experienced reliever, Mychal Givens, to the Colorado Rockies on Sunday for two infielders, Tyler Nevin and Terrin Vavra, and a player to be named later.

It was the Orioles second trade on Sunday. Earlier, they traded left-handed starting pitcher Tommy Milone to the Atlanta Braves for a player to be named later.

Givens, who was drafted in the second round as an infielder by the Orioles in 2009, was converted to a relief pitcher in 2012 and made his major league debut in 2015.

In six seasons, he was 20-17 with a 3.32 ERA and 20 saves.

Givens had his best seasons serving as a setup man for Zack Britton, Darren O’Day and Brad Brach from 2015-2017, but once those three were traded in July 2018, Givens struggled as a closer.

This season, he was 0-1 with a 1.38 ERA in 12 games and wasn’t used as a closer.

Nevin, 23, was a first-round pick of the Rockies in 2015, the 38^th pick overall, and last year hit .251 with 13 home runs and 61 RBIs in 130 games for Double-A Hartford. Both Nevin and Vavra were at the Rockies’ alternate site.

He is the son of New York Yankees third base coach Phil Nevin. He’s primarily a first baseman, but the right-handed hitter also plays third.

Vavra, who’s also 23, is the son of longtime major league coach Joe Vavra. A left-handed hitter who plays shortstop and third, Vavra was the third-round pick of the Rockies in 2018.

At Low-A Asheville last year, Vavra hit .318 with 10 homers and 52 RBIs.

The acquisitions of Nevin and Vavra help shore up the Orioles’ stock of infielders in the minor leagues, an area of weakness.

To replace Givens and Milone on the roster, the Orioles promoted left-handed pitcher Keegan Akin from the alternate site at Bowie and reinstated right-hander Hunter Harvey from the 10-day injured list.
