Fresh off a series win over the Boston Red Sox earlier this week, the O’s will continue to finish out their AL East schedule when they travel to Toronto for a weekend series.

The last time these two teams met, the Baltimore Orioles not only beat the Toronto Blue Jays, but they swept them at Camden Yards. Baltimore’s wins delivered the first three wins against Toronto this season after losing 12 straight games.

Manager Buck Showalter has announced his starters for Friday night and Saturday afternoon, but Sunday is still undetermined. With that said, here’s the matchups.

Friday night, Chris Tillman (1-4, 6.42 ERA) will take the hill. Tillman has made nine starts this season, earning only one win. The rookie right-handed pitcher has struggled in the majority of his outings, including the last two, in which he’s allowed six walks in each start. Opposing Tillman will be lefty Brett Cecil (13-7, 4.25). Cecil has one start against the O’s this season. In that start, he went eight innings and allowed two earned runs, but that was all the way back in late May. His ERA has been rising steadily recently even though he has earned wins in his last two decisions.

Saturday afternoon, Jeremy Guthrie (10-14, 3.92) will start. Guthrie has been pretty good in the second half, but had a miserable outing against the New York Yankees in his last start. Guthrie allowed six earned runs in just five innings in that outing. Against the Blue Jays this season, Guthrie has started three times, losing twice. In his starts against Toronto, Guthrie has pitched 19.2 innings and allowed just six runs (five earned). Left-handed pitcher Ricky Romero (13-9, 3.75), who has beaten the O’s three times in three tries this season, will pitch against Guthrie. Romero is a tough lefty that the O’s offense hasn’t cracked yet. In his last outing against Baltimore on July 27, Romero went 7.2 innings and allowed just two earned runs.

Sunday afternoon, the O’s have an open spot at starter. However, the offense will face righty Shaun Marcum. Marcum (3.77, 12-8), has been very good against the O’s this season. He has pitched 17 innings in his three starts against the Birds, winning two of them. In his starts, he has exhibited extremely good control against the Orioles in 2010, walking just three batters while striking out 16.
