In two starts this season against the Blue Jays, he is 1-1 with a 5.06 ERA. In 10 2/3 innings, he has given up 17 hits. In three career starts versus Toronto, Chen is 1-2 with a 6.32 ERA. Left-hander J.A. Happ (10-11, 4.27 ERA) gets the start this afternoon for Toronto. In four games (three starts) this season against the Orioles, he is 1-2 with a 3.18 ERA. The Orioles have won the season series against Toronto for the third year in a row. It is the first time the Orioles have done that since 1994-96. After losing six and tying one season series against Toronto from 2005-11, the Orioles went 11-7 in 2012, 10-9 last year and are 10-7 this season. That is a three-year mark of 31-23. According to STATS, the Orioles have never won more than 11 games against Toronto in a single-season, and they did that in 2012, 2004, 1980 and 1979.

The Orioles by month: March/April - 12-12 May - 15-15 June - 16-12 July - 17-8 August - 19-9 September - 16-9 Update: Chen pitched six solid innings and Adam Jones hit his 29th homer of the year, but fielding hampered the Orioles again. The Blue Jays won 4-2 in part because of three more Orioles errors this afternoon - one each from third baseman Alexi Casilla, first baseman Christian Walker and reliever Brad Brach. The O's have committed seven errors in the last three games and Baltimore third basemen have committed six errors in the last nine contests. Chen allowed three runs (two earned) on five hits while walking one and fanning three in six innings. But he took the loss to end the regular season 16-6 with a 3.54 ERA. The Orioles have now lost three straight and are 95-66 heading into tomorrow's regular season finale.
