I did the Baseball-Reference query on this, just to see what showed up.
The actual number I came up with is 43 (44 if you use ER instead of R), which still is amazing.
He went at least 7 IP in 34 of those, at least 6 IP in 40.
Seattle went 20-24 in those games, scoring two runs or fewer in 19 of the losses.
Oddly enough, only 12 of the 44 did he give up 0 runs, the rest were 1 (or 2, in the one game that one of the runs was unearned).
On June 8, 2014 at Tampa Bay he struck out 15 in 7 innings and left in a scoreless tie. The Mariners scored five times in the ninth.
