Red Sox’ Darwinzon Hernandez set to begin rehab assignment with Triple-A Worcester

Red Sox reliever Darwinzon Hernandez has been sent out on a rehab assignment with Triple-A Worcester, per The Boston Globe’s Alex Speier.

Hernandez, 24, has not appeared in a game for the Sox since July 29 after being placed on the 10-day injured list on account of a right oblique strain two days later.

At the time Hernandez initially hit the IL, it did not appear as though the left-hander would be out for long, but he wound up undergoing an MRI — which came back clean — in early August.

On August 15, Hernandez resumed playing catch and threw a bullpen session at Fenway Park the following weekend. He completed his second live bullpen session on Sunday, which seemed to be one of the final hurdles he needed to clear.

That being the case because Red Sox manager Alex Cora told reporters (including The Athletic’s Jen McCaffrey) on Sunday that the team was trying to determine if Hernandez would need to go on a rehab assignment or if he would just be immediately activated from the injured list.

As it turns out, Hernandez will indeed head out to Worcester to join the WooSox ahead of their six-game series against the Lehigh Valley IronPigs that begins Tuesday night at Polar Park.

Before straining his right oblique in late July, the Venezuelan southpaw had posted a 3.44 ERA and .697 OPS against to go along with 46 strikeouts and 26 walks over 41 relief appearances spanning 34 innings of work out of the bullpen.

In the time that Hernandez has been sidelined, the Red Sox have used four additional left-handed relievers in Josh Taylor, Austin Davis, Martin Perez, and Stephen Gonsalves.

Those four lefties have combined to put up a 4.98 ERA, a 3.72 FIP, a 4.08 xFIP, and strikeout-to-walk ratio of 37:16 over 34 1/3 total innings pitched in Hernandez’s absence dating back to July 30.

As noted by Speier, Hernandez’s time away from the team has been ‘significant’ given his ability to induce punchouts at a relatively high rate (29.9% this season).
