Jung is correct that the NESN team of Remy and O'Brien seem to pass up some fairly obvious situations. But look at who signs their checks. Eckersley speaks truth to power
Watch how he is stretching and grimacing as he tries to loosen the left arm or shoulder between pitches. Sure looks like a physical impingement, not just the resulting hitch that you commented on.
10 K's , 100 pitches and 2 run double to a guy hitting below .180. Now it will be 12 outs from the BP, unless Cora let's Price start the 6th for one or two batters. Meanwhile Sox hitters through 5 resting on Moreland's solo shot.
When Moreland is on target, he is the quintessential first baseman. Great glove and power bat. Maybe Devers could take lessons on how to swing like a LH'er
