From MLB.com:
Guthrie ran up a high pitch count in his last start and made a fine art of surviving into the middle innings. The right-hander wound up working into the sixth inning, establishing a new season-high pitch count (114). Guthrie, Baltimore's Opening Day starter in each of the past two seasons, has allowed more home runs (31) and more earned runs (106) than any other American League starter.
Richmond is 0-5 with an 8.92 ERA in eight starts since returning from the disabled list, where he spent a month with a sore right shoulder. The Blue Jays have lost seven of those games. He lasted two innings against the Rays in his last outing, allowing five runs on seven hits. He has given up 22 runs in 17 1/3 innings over his past four starts
