The Red Sox optioned Criswell to Triple-A Worcester on Tuesday, Jen McCaffrey of The Athletic reports.
Criswell will give up his active roster spot to Chris Martin (personal), who's being activated from the 15-day IL. Criswell posted a 4.15 ERA across 52.0 innings with Boston and should be one of the first options the Red Sox look at if a starter were to get injured.

Rotowire
Criswell allowed two runs on three hits and two walks while striking out six over four innings in a no-decision versus the Yankees on Saturday.
The Red Sox jumped out to a quick lead, but Criswell didn't pitch deep enough to qualify for the win. He needed 88 pitches (55 strikes) to complete his four frames, making this the seventh time in 12 appearances (11 starts) he's failed to complete five innings. The 27-year-old has a 4.15 ERA, 1.21 WHIP and 49:13 K:BB over 52 innings this season. Criswell is tentatively projected to make his next appearance on the road versus the Reds.
Criswell (3-3) yielded four runs (three earned) on five hits and a walk over 4.1 innings Friday, striking out two and taking a loss against the White Sox.
Criswell gave up one run through three frames before the White Sox plated three runs in the fourth inning. It was the third time in his last five outings that he's failed to complete at least five innings. During that stretch, he's posted a 6.45 ERA, driving his season number up to 4.13. Criswell is currently in line for a home matchup against the Yankees next week.
Criswell (3-2) picked up the win Saturday, allowing one run on four hits and a walk over five-plus innings. He struck out five.
He gave up a leadoff double to Matt Vierling and watched him come around to score, then had Vierling rip another two-bagger off him to begin the fifth inning, but Criswell shut down the Detroit offense in between. It was a strong rebound from the right-hander after he got tagged for seven runs in his last outing. Criswell will take a 3.92 ERA, 1.19 WHIP and 41:10 K:BB through 43.2 innings into his next start, which lines up to come on the road next weekend against the White Sox.
